Ch. 22 :musculoskeletal system Flashcards
joints
+nonsynovial (immovable) and synovial joints (freely movable)
+cartilage: cushions bones and gives smooth surface to facilitate movement
+ligament: run from one bone to another. strengthen the joint and prevent undesirable direaction of movement
+bursa: enclosed sac filled with synovial fluid. helps muscles and tendons glide smoothly over bone
muscles
+account for 40-50% of body’s weight
+skeletal muscles
-Fasciculi- bundles of muscle fibers
-tendon- strong fibrous cord which attaches to bone
-skeletal muscle movements (flexion/extension, abduction/adduction, inversion/eversion, protraction/retraction, rotation, elevation/depression, pronation/supnation, circumfrence)
Tempoormandiubular joint (structure)
articulation of mandible and temporal bones
spine (structure)
\+vertebra- 33 connecting bones -7 cervical -12 toracic -5 lumbar -5 sacral -3-4 coccygeal vertebrae \+intervetebral disks \+landmarks: T1, C7, T7,T8,T12,L1,L4,S2 and scapula
shoulder (structure)
- glenohumeral joint
- rotator cuff
- subacromial bursa
- acromion process
- greater tubercle of the humerus
- coracoid process
Elbow (structure)
- 3 bony articulations of the humerus, radius, and ulna
- medial and lateral epicondyles
- olecranon process of ulna
wrist and carpals (structure)
- radiocarpal join
- midcarpal joint
- metacarpophalangeal joints
- interphalangeal joints
Hip
- acetabulum and head of femur
- anterior superioir iliac spine
- ischial tuberosity
- greater trochanter of femur
Knee
- femur, tibia, and patella
- suprapatella pouch
- medial and lateral menisci
- cruciate ligaments
- prepatella bursa
- quadriceps muscle
ankle and foot
- tibiotala joint
- medial and lateral malleolus
- metatarsals
dev. care
+growth plates closure @ age 20
+lordons: lower back arches
+good for bones bone: dark green leafy. beans. almonds
obj. data
-preperation:
+screening musculoskeletal exam: for most people, normal screening. inspection and palpation of joints integrated and ROM
+complete musculoskeletal exam: appropriate for a persons with articular disease, a history of musculoskelteal symptoms, or any problems with ADLs
Oder of exam
+inspect: size, contour of joint, skin, tissue over joint for color, swelling, massses, or deformity
+palpate: skin temp., muscles, bony articulations, area of joint capsules
Range of motion
active/passive
muscles testing
- apply opposing force
- grading muscle strength
