Objectives: Overview of Muscle Tissues. Deltoid muscle Humerus Bicipital groove Tendon of the long head of the biceps brachii (short axis) Greater tuberosity Lesser tuberosity. • Un natural movements seen in the patient when muscles are paralysed or inhibited. The deltoid muscle is the site most typically used for vaccines. Axial skeleton – longitudinal axis of body, Form internal framework: supports body & cradles soft organs, Ex: skull bones fused to enclose the brain, Skeletal muscles attached to bone via tendons, move body and its parts, Results in full body locomotion, fine movements, internal movements, Bones store minerals: calcium & phosphorus, needed for nervous impulses, muscle contraction, blood clotting, Hormones control movement of calcium to and from bones and blood, Classification of bones on the basis of shape, 4 shapes of bone: long, short, flat, irregular, All the bones of the limbs (except patella, ankle & wrist), Bones of the wrist (carpal) & ankle (tarsal).

Amphiarthrotic Examples (slightly movable): Intervertebral joints (fibrocartilage discs between), Epiphyseal plates (hyaline cartilage) of long bones, Costal cartilages between first ribs and sternum (hyaline), Articulating bones are separated by a joint cavity filled with synovial fluid, Articular cartilage (hyaline) covers the ends of bones, A fibrous articular capsule encloses joint surfaces; lined with synovial membrane, Joint cavity is filled with synovial fluid, Structures Associated with the Synovial Joint, Bursae (AKA purses) – flattened fibrous sacs, Act like ball bearings by reducing friction, Common where ligaments, muscles, skin, tendons, or bones rub together, Elongated bursa that wraps around a tendon, – bone forced out of normal position in the joint cavity, – process of returning the bone to its proper position, Cylindrical end of one bone fits into trough-shaped surface of another bone, Rounded end of one bone fits into sleeve or ring of bone, Proximal radioulnar joint and joint between atlas and dens of axis, Egg-shaped surface of one bone fits into oval concavity of another bone, Biaxial = movement around two axes; but, not around long axis, Articular surfaces have convex and concave surfaces, Biaxial – similar movements as condyloid joints, Spherical head of one bone fits into round socket of another, Multiaxial joint – movement in all axes, including rotation, inflammation of a bursa or synovial membrane usually caused by a blow or friction, ligaments or tendons of joint are damaged by excessive stretching or are torn from bone, Tendonitis – inflammation of tendon sheaths, Arthritis: inflammatory or degenerative diseases of joints, Over 100 different types; most widespread crippling disease in the United States, Acute arthritis caused by bacterial infection; treated with antibiotics, Chronic arthritis: osteoarthritis, rheumatoid arthritis, gouty arthritis, Chronic degenerative condition related to normal aging processes, Erosion of articular cartilages, formation of bone spurs, restricts joint movement, crepitus, painful, Chronic inflammatory disorder occurring between the ages of 40-50; affects more women than men, Mostly in hand, wrist, foot, and ankle joints (symmetrical), An autoimmune disease—the immune system attacks the joints, Symptoms begin with inflammation of synovial membranes, accumulation of synovial fluid; inflammatory cells destroy tissues, Inflammation of joints is caused by a deposition of uric acid crystals from the blood, Typically affects a single joint, such as the great toe, More common in men; after age of 30; probably genetic, Developmental Aspects of the Skeletal System, First long bones made of hyaline cartilage, Earliest flat bones are fibrous membranes, During fetal development both are converted to bone, Fontanels remain upon birth to allow for brain growth, but ossify by 2 years of age, Epiphyseal plates become ossified and long bone growth ends, 8 or 9 years old—skull is near adult size and proportion, Between ages 6 and 11, the face grows out from the skull, Primary curvatures are present at birth and are convex posteriorly, Secondary curvatures are convex anteriorly and are associated with a child’s later development, Result from reshaping of the intervertebral disks, Abnormal spinal curvatures (scoliosis and lordosis) are often congenital, but can result from injuries, Birth—head & trunk = 1.5x longer than lower limbs, Lower limbs grow faster than trunk; reach ~= length as head & trunk by age of 10, Puberty—female pelvis broadens; male skeleton becomes more robust, Disease makes bones fragile and bones can easily fracture, Vertebral collapse results in kyphosis (AKA dowager’s hump), Estrogen aids in health and normal density of a female skeleton after menopause, Other contributing factors: diet low in calcium and protein, low vitamin D, smoking, insufficient weight-bearing exercise, Elderly often suffer from pathologic fractures by avoiding doing anything too physical, Osteoarthritis also occurs in weight-bearing joints. - Tendon of extensor hallucis longus muscle. Sesamoid bones – bones which form within tendons; Two thin layers of compact bone surround a layer of cancellous bone, Do not fit into other bone classification categories, Thin layer of compact bone enclosing cancellous bone, Covers the external surface of the epiphyses, Flat plate of hyaline cartilage seen in young, growing bone, Hormones inhibit long bone growth by the end of puberty, Epiphyseal plate is replaced by bone, leaving epiphyseal line behind, Contains yellow marrow (mostly adipose tissue) in adults, In infants, contains red marrow (for blood cell formation), In adults, red marrow is in cavities of cancellous bone (flat bones) and in epiphyses (long bones), Sites of attachments for muscles, tendons, and ligaments, Projections or processes—grow out from the bone surface, Distal femur, posterior mandible, occipital condyles, Mastoid process (temporal), styloid process (distal radius & ulna), Tubercle: greater & lesser tubercle on humerus, conoid tubercle (inferior edge of lateral clavicle), Tuberosity: radial tuberosity, tibial tuberosity, deltoid tuberosity (humerus), Greater & lesser trochanters on proximal femur, Superior orbital fissure, inferior orbital fissure, Olecranon fossa (posterior, distal humerus), Fovea capitus on femoral head (fovea smaller than fossa), Lacunae – tiny cavities housing osteocytes, Lamellae – concentric circles (layers) of lacunae & matrix, Central (Haversian) canals – passageway for blood vessels & nerves, Radiate from the central canal to lacunae, Form a transport system connecting all bone cells to nutrient supply, In embryos, the skeleton is primarily hyaline cartilage, During development, much of this cartilage is replaced by bone, Other bones develop from hyaline cartilage models, Hyaline cartilage model covered with bone matrix, Hyaline cartilage model digested away, forming a medullary cavity, Two locations remain as cartilage after birth: articular cartilages (covering ends of bones) and epiphyseal plates, New cartilage is continuously formed on external surface of articular cartilage and epiphyseal plate, Enclosed cartilage is digested away, opening up a medullary cavity, Bone replaces cartilage through the action of osteoblasts, Osteoblasts (from periosteum) add bone to outside of diaphysis, Osteoclasts (in endosteum) remove bone from inside of diaphysis, Both occur at approximately the same rate, resulting in larger diameter, Long-bone growth controlled by hormones; ends in puberty, Bones are continually remodeled in response to two factors, Pull of gravity and muscles on the skeleton, Break down bone matrix for remodeling and release of calcium in response to parathyroid hormone, Bone remodeling is performed by both osteoblasts & osteoclasts, ↑ Ca resorption from urine in kidney back into blood, = high blood calcium, decreases osteoclast activity, Bone Remodeling = depositing new bone matrix in a mature bone, In order to retain normal proportions & strength during long-bone growth, In order to form projections where muscles attach, Atrophy in bedridden or physically inactive people, abnormally increased size, excessive endochondral growth @ epiphyseal plates, person is abnormally small, improper growth @ epiphyseal plates, (bone + production + imperfect) – genetic disorders causing brittle bones with insufficient collagen; easily fractured, especially in fetus; poor healing/misalignment, Children with lack of calcium or Vitamin D in diet, bone marrow inflammation, can be caused by, (type of bacterium) through wounds or tuberculosis, (bone softness) – due to calcium depletion from bones; pregnancy or “Adult Rickets” from vitamin D deficiency, Closed (simple) fracture — break that does not penetrate the skin, Open (compound) fracture — broken bone penetrates through the skin, Bone fractures are treated by reduction and immobilization: realignment of the broken bone ends, : bones realigned via internal surgery and secured with pins/wires/plates, Note: joint immobilization during mid-late bone healing results in 3x decrease in strength, Bone not subject to the stresses that helps it form, Break is splinted by fibrocartilage to form a callus, Fibrocartilage callus forms; contains cartilage matrix, bony matrix, collagen fibers, Fibrocartilage callus is replaced by a bony callus, Bony callus is remodeled to form a permanent patch, Skull (28 bones including auditory ossicles), Two sets of bones: cranium & facial bones, Only the mandible is attached by a freely movable joint, These bones transmit vibration to eardrum, Joined to temporal by squamous suture (scale-like), Joined to frontal by coronal suture (crown), Joined to occipital by lambdoid suture (λ), Inferior part of cranium & part of cranial floor, Joined to occipital and parietal by squamous suture, External acoustic (auditory) meatus – sound waves travel through to eardrum, Styloid process– muscle attachment for tongue, hyoid, & pharynx movement, Zygomatic process– articulates with zygomatic, Mastoid process– neck muscle attachment for head rotation, Mandibular Fossa – articulates with mandible, Lambdoid suture - joined to parietals by lambdoid suture, Foramen magnum– passage of spinal cord (connects to brain), Occipital condyles– articulate with vertebral column, Posterior part & prominent portion of the base of the cranium, Superior nasal concha & middle nasal concha, Light, spongy bone that increases surface area of nasal cavity, Anterior floor of the cranium between the orbits, Composes much of nasal cavity & part of nasal septum, Perpendicular Plate – part of nasal septum (with vomer), Facial bones: holds eyes & support facial muscles, Hollow portions of bones surrounding the nasal cavity, Give resonance and amplification to voice, The only bone that does not articulate with another bone, Attachment point for neck muscles that raise/lower the larynx during swallowing and speech, Infant’s face is very small compared to cranium size, Fetal skull is large compared to the infant’s total body length, Fontanels — fibrous membranes connecting the cranial bones; AKA, Allow skull to be compressed during child birth, Allow the brain to grow during latter pregnancy and early infancy, Convert to bone within 22-24 months after birth, Extends from skull (support) to pelvis (transmits body weight to lower limbs), Composed of 26 irregular bones, connected by ligaments, creating a flexible and curved structure, Intervertebral discs: pads of fibrocartilage in between vertebrae, Homeostatic Imbalance: Herniated (slipped) discs, Weakening of ligaments of vertebral column, If disc presses on spinal cord or spinal nerves, can cause numbness and pain, Can occur during childbirth and from falls, Primary curvatures are the spinal curvatures of the, Secondary curvatures are the spinal curvatures of the, Lumbar curvature provides ability to center body weight on lower limbs; develops as a baby begins to walk, Cervical curvature develops as a baby begins to raise its head, : congenital, due to disease, poor posture, unequal muscle pull on spine, Body/centrum – bears weight; faces anteriorly, Vertebral arch – created by posterior extensions; forms vertebral foramen, Lamina – extend from transverse process to spinous process, Pedicle – extend from body to transverse process (feet), Transverse process – extend laterally from the vertebral arch between pedicle & lamina, - project dorsally from laminae; can feel externally, - notches formed by adjacent vertebrae; spinal nerves exit here, – formed by all vertebral foramina; spinal cord passage/protection, Large articular facets that articulate with occipital condyles (holds head up), Short spinous processes; some have branched spinous processes, Transverse processes contain foramina for vertebral arteries going to brain; only present in cervical vertebrae, Only vertebrae that articulate with the ribs, 2 lateral articular facets for rib articulation, Transverse processes articulate with rib tubercles, Long, thick spinous processes hooks sharply down: giraffe head, Heavy, rectangular spinous process; moose head, Medially facing superior articular facets (“locks” vertebrae together for stability), Alae articulate with ilia (hip bones) laterally at the sacroiliac (SI) joint, Median sacral crest – fused spinous processes of the sacral vertebrae, Sacral canal – continuation of vertebral canal, Site of anesthetic injection prior to childbirth, Sacral promontory – bulge in anterior edge of body of 1, Palpated before childbirth to determine pelvic opening size, Formed from the fusion of three to five vertebrae, “Tailbone,” or remnant of a tail that other vertebrates have, Forms a cage to protect heart, lungs, and major vessels, Jugular notch – concave superior border of manubrium; @ T, Sternal angle – junction of manubrium & body; @ 2, intercostal space (heart valve auscaultation, Xiphisternal joint – junction of body & xiphoid process; @, Articulate posteriorly with vertebrae, then curve downward anteriorly, True ribs: pairs 1-7; attach to sternum via costal cartilages, False ribs: pairs 8–12; attach indirectly to sternum or not at all, Floating ribs: pairs 11–12; no sternal attachment, Intercostal spaces – spaces between ribs are filled with muscles that air in breathing, Articulates with the manubrium medially an with the scapula laterally, Points over top of shoulder; anchors some arm muscles, Scapula not attached directly to skeleton, Superior, medial (vertebral), and lateral (axillary), : receives head of humerus (forms lateral angle). It can only receive small volumes of medication, usually 1 milliliter or less. Polymyositis is degenerative and inflammatory in nature.
