Term
Joint
Definition
2 or more bones or articulate and movement occurs
Term
Ligament
Definition
Fibrous tissue connect bone to bone; reinforce joints from dislocation,non elastic limited ROM(range of motion)
Term
Tendon
Definition
Band of dense fibrous tissue forming the termination of the muscle and attaching muscle to bone
Term
Cartilage
Definition
white semi opague fibrous connective tissue , cushions and prevents wear on articular surfaces
Term
anterior/posterior
Definition
front/back of organ or body
Term
medial/lateral
Definition
toward midline/ away from midline(side)
Term
supine/prone
Definition
laying face up/face down
Term
superior/inferior
Definition
above/below
Term
unilateral/bilateral
Definition
affects one side/ both sides
Term
anatomical planes- horizontal(transverse)
Definition
top half(trunk)/ bottom half (hips/legs)
Term
anatomical planes-sagittal
Definition
left side/right side
Term
anatomical planes -frontal
Definition
anterior/posterior
Term
flexion
Definition
bending motion, decreases the angle b/t 2 bones of joint
Term
extension
Definition
The opposite of flexion; a straightening movement that increases the angle between body parts
Term
abduction
Definition
mvmt away from midline of body
Term
adduction
Definition
mvmt towards midline of body
Term
rotation
Definition
mvmt around an axis
Term
circumduction
Definition
circular mvmt of ball and socket joint-example "windmilling" rotating in circular motion  
Term
agonist
Definition
muscle that is the prime mover, responsible for action
Term
antagonist
Definition
acts in opposition to the action produced by prime mover
Term
prime movers
Definition
agonists
Term
assistors
Definition
antagonist
Term
stabilizers
Definition
prevents undesired or unnecessary motion
Term
isometric
Definition
contraction where muscle tension and muscle length remain constant
Term
concentric
Definition
muscle shorten (bicep curl-"tricep")
Term
eccentric
Definition

the muscle elongates while under tension due to an opposing force being greater than the force generated by the muscle.

(toe touch stretch "hamstring)

Term
isotonic
Definition
 muscle tension remains constant and muscle length varies
Term
isokinetic
Definition
muscle contraction varies in tension and length
