NUR 362 - MUSCULOSKELETAL Flashcards
Components of the Musculoskeletal System
bones muscles joints tendons ligaments cartilage bursa
Normal Physiologic Function of Musculoskeletal System
alignment and posture balance coordinated movements protection production storage
Bone
specialized connective tissue
hard, rigid, dense
Joint
union of two or more bones
non-synovial (immovable and slightly movable)
synovial (freely movable due to separation from fluid-filled cavity)
Cartilage
cushions the bones and gives smooth surface to facilitate movement
Ligaments
connect bone to bone
give bone structure to form the joint
Bursa
fluid filled sac
any place where there’s a joint
Tendon
connect muscle to bone
helps with function of ROM
Muscular Strength - 0
no muscular contraction detected
Muscular Strength - 1
barely detectable flicker or trace contraction
Muscular Strength - 2
active movement of body part with gravity eliminated
Muscular Strength - 3
active movement of body part against gravity
Muscular Strength - 4
active movement of body part against some resistance
Muscular Strength - 5
active movement of body part against full resistance without fatigue
ADLs
bathing dressing eating grooming mobility (transfers, ambulation, toiling)
Palpation of musculoskeletal system
heat tenderness swelling crepitus nodules AROM/PROM muscle strength
TMJ Palpation
tips of first two fingers and ask person to open/close mouth
palpate contracted temporals and masseter muscles as person clenches
compare size, firmness, strength
TMJ ROM
open/close - against resistance tests trigeminal nerve (V)
protraction/retraction
lateral movement
Cervical Spine Inspection
alignment of head and neck
spine should be straight and head erect
Cervical Spine Palpation
spinous processes for tenderness
sternomastoid, trapezius and paravertebral muscles
