muscoskeletal Flashcards
What are some examples of skeletal muscles?
the gluteus maximuus/medius
vastus medialis,lateris
what is striated muscle and it’s funtion ?
striated muscles are highly organized tissues that convert chemical energy to physical work.
the primary funtion is to generate force in order to support posture(skeletal) and pump blood through the body(cardiac muscle).
what are voluntary muscles in the skeleton?
voluntary muscles contract and relax under concious control
what are visceral muscles in the skeleton?
these are smooth muscles and they are found in the viceral organs of the body such as the digestive tract and urinary tract. these will work automatically

Lordosis is an inward curvature of the spine / sway back
Flat back means the pelvis tucks in and the lower back is straight instead of naturaly curved causing you to stoop forward
what are some of the special properties of muscle cells that help enable them to carry out their funtion?
irratibility or responsiveness is the ability to respond to stimulus
contractibility is ability shorten when stimulated
extensability is the ability of all muscle cells to be stretched
elasticity is thirt ability to resume their resting length after being stretched
what are the six types of muscle movements ?
flexion
extention
rotation
abduction
adduction
circumduction
abduction
what are the four special movements of muscles ?
dorsiflexion is up and down movements of the foot
Inversion/eversion is to invery the sole of the foot
supination/pronation refers to the movement of the radius around the ulner
opposion is thumb to tip of any fingrer
