Muscular MISC
rigidity of muscles which takes place after death
Rigor Mortis
muscle end attached to stationary bone
origin
the muscle which opposes or reverses the action to control and stabilize the action
antagonist
expands the angle between two body parts
extension
stronger contractions causing body movement
isotonic contractions
the end of a muscle attached to the bone being moved
insertion
movement away from the midline of the body
abduction
mild contractions which increase muscle tension, but do not stimulate enough force to move a body part
isometric contractions
Muscles which support the movement by contributing force and/or stabilizing bones and joints involved
Synergists
movement towards the midline of the body
adduction
the main portion of a muscle
body
reduces the angle between two body parts
flexion
rotation that shoulder and hips rotates the structure toward the midline of the body
internal rotation
principle muscle responsible for the action movement
agonists
rotation of the shoulder and hips which the structure away from the midline of the body
external rotation
