how many bones in the adult human body?
206
axial skeleton
head, neck and trunk
appendicular skeleton
legs and arms
periosteum
tissue surrounding bone
isotonic contraction
moving
concentric contraction
type of isotonic contraction, muscle’s action
eccentric contraction
type of isotonic contraction, outside force pulling outward while muscle pulls
isometric contraction
muscle pulling but no motion
isokinetic contraction
velocity of muscle contraction remains constant while muscle lengthens
passive movement
you move the patient while they remain passive
resisted movement
partner performs an action against gentle resistance
3 principles of palpation
move slowly, avoid using excessive pressure, focus awareness on what you’re feeling
largest organ of the body
skin
epimysium
layer of fascia that encases the muscle
perimysium
layer of fascia surrounding muscle fibers into bundles
endomysium
fascia that wraps around each muscle fiber
agonist
muscle that carries out an action
synergist
muscle that supports the agonist
anatgonist
muscle that works against the agonist
parallel muscles
long muscle fibers that run parallel to the length
pennate muscles
shorter fibers that run obliquely to their tendons
tendon
attaches muscle to bone
ligament
connects bone at the joint
fascia
continuous sheet of fibrous membrane
superficial fascia
located immediately deep to skin, covers entire body
deep fascia
surrounds muscle bellies, holds them together while separating each muscle
retinaculum
structure that holds an organ or tissue in place
Can you feel a pulse on an artery or vein?
artery
bursa
small fluid filled sack which reduces friction between 2 structures
bursitis
inflammation of a bursa, causes tenderness & crepitation of the joint
nerve
tube-shaped, mobile & tender when compressed
lymph node
collect lymphatic fluid from lymphatic vessels
planes of movement
frontal, transverse, sagittal
cranial
closer to head
caudal
closer to buttocks
protraction
(abduction) pushes dumbbells away from body
retraction
(adduction) pulling dumbbells towards body
fossa
shallow depression
osteoporosis
bones start to become brittle and weak due to inability to replace bone tissue
degree of freedom
number of planes a joint can move
