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
