orgin

muscle attached to immovable bone

insertion

the moveable end of a muscle

nonaxial movement

slipping movements only, no axis around which movement can occur

uniaxial movement

synovial joint motion; movement in one plane (ex. elbow)

biaxial movement

synovial joint motion; movement in two planes (ex. knuckle)

multiaxial movement

synovial joint motion; movement in three planes (ex. shoulder)

gliding,angular movements,and rotation

what are three types of movement

gliding

Partially movable joint where bones slide over one another.

angular movements

flexion and extension; abduction & adduction, increase or a decrease in the angle between articulating bones. Include flexion, extension, hyperextension, abduction, lateral flexion, adduction and circumduction.

rotation

circular movement around an axis,the only movements allowed are between the first vertabre and is common at the hip and shoulder joints

flexion

Bending parts at a joint so that the angle between them decreases and the parts come closer together

extension

the opposite of flexion: the angle between the articulating bones increases and the body part straightens e.g. straightening the leg at the knee.

hyperextension

The extreme backward movement of the head, causing injury to the posterior vertebral structures and anterior ligaments.

dorsiflexion

flexing the foot at the ankle toward the shin

plantar flexion

Extension of the toes or foot so that they point downward

abduction

moving away from the midline

lateral flexion

Movement of the trunk sideways to the right or left at the waist

adduction

Movement towards the midline

circumduction

moving a limb so that it describes a cone in space

supination

rotation of the hands and forearms so that the palms face upward

pronation

rotation of the hands and forearms so that the palms face downward

inversion

turning the sole of the foot inward

eversion

turning the sole of the foot outward

protraction

Moving the mandible into a position anterior to normal.

retraction

moving your jaw back into itsoriginal position

elevation

movement upward, as in shrugging the shoulders

depression

Lowering a body part

opposition

Movement of the thumb to touch the fingertips saddle joints
