Movements KIN 2500 (Exam 3)

Terms in this set (24)

gliding
nearly flat bone surfaces move from side-to-side and back-and-forth
angular movements
an increase or decrease in the angle between articulating bones.
flexion
decrease in angle between articulating bones
flexion, extension, lateral flexion, hyperextension, abduction, adduction, and circumduction
What are the major angular movements?
extension
an increase in the angle between articulating bones, often to restore a part of the body back to the anatomical position, after it has been flexed
lateral flexion
occurs along the frontal plane and involves intervertebral joints ; involves the movement of the trunk sideways to the right or left of the waist
hyperextension
continuation of extension beyond the anatomical position
abduction
(radial deviation); the movement of a bone away from the midline
adduction
(ulnar deviation); the movement of a bone toward the midline
circumduction
movement of the distal end of a body part in a circle
rotation
a bone revolves around its own longitudinal axis
special movements
occur only at certain joints
elevation, depression, protraction, retraction, inversion, eversion, dorsiflexion, plantar flexion, supination, pronation, and opposition
what are the special movements?
elevation
a superior movement of a part of the body
depression
an inferior movement of part of the body
protraction
movement of part of the body anteriorly in the transverse plane
retraction
movement of a prorated part of the body back to the anatomical position
inversion
movement of the sole medially at the inter tarsal joints
eversion
movement of the sole laterally at the inter tarsal joints
dorsiflexion
refers to bending of the foot at the ankle or talocrural joint in the direction of the dorm (superior surface)
plantar flexion
bending of the foot at the ankle joint in the direction of the plantar or interior surface
supination
movement of the forearm at the proximal and distal radioulnar joints in which the palm is turned anteriorly
pronation
movement of the forearm at the proximal and distal radioulnar joints in which the distal end of the radius crosses over the distal end of the ulna and the palm is turned posteriorly
opposition
movement of the thumb at the carpometacarpal joint in which the thumb moves across the palm to touch the tips of the fingers on the same hand
