Kinesiology Ch. 5

vector

arrow drawn to represent the line of pull of a muscle direction arrow head pointed shows us line of muscle being pulled length is magnitude of muscle's pull

muscles

nerve hits to create a movement MUSCLES ALONE DO NOT CREATE MOVEMENT

joint action

action is a specific cardinal plane movement of the body directional term describing direction of action state which body part moved during action state at which joint the action occured

planes of motion frontal

adduction abduction elevation depression inversion eversion

joints

allow movement also called articulation weight bearing, shock absorption, and stability

non-axial motion

body part that doesn't occur around an axis also known as gliding every aspect of body part moves at the same amount linear path translation

axial motion

body part that occurs about or around an axis also known as circular motion angular and rotary point closer to axis moves less and would transcribe in smaller circle

angular motion

direction of motion for every point on the body is through the same angle

planes of motion sagittal

flexion extension dorsiflexion plantarflexion

ipsilateral rotation

if a muscle rotates an axial body part toward the same side of the body as where it is located

contralateral rotation

if muscle rotates an axial body part toward the opposite side of the body from where it is located

joint capsules

limit movements

right lateral deviation

movement at a joint that brings a body part to the right movement occur in frontal or transverse plane axial or non-axial

curvilinear non axial motion

person body is at a curve and not straight

roll, spin, and glide

roll (axial) spin (axial) glide (non-axial)

rolling and spin axial movement

rolling movement is when the body part changes its position in space and one end of the bone moves more than the other end rolling can also be called rocking spinning is when the body part doesn't change its position in space; staying in same location

planes of motion transverse

rotation supination pronation horizontal flexion horizontal extension

rectilinear non axial motion

straight type of motion
