joints and movements Flashcards
(13 cards)
what are the three classifications of joint movement
no movement, slight movement, full movement
what are the three joints in the no movement classification
sutures: non-moving joints that connect bones in the skull
gomphoses: fibrous articulations between the teeth and mandible
synchondroses: immovable cartilaginous joints between the first pair of ribs and the sternum
what are the two joints in the slight movement category
syndesmosomes: ligaments that connect two bones
sympheses: fibrocartilaginous pads that connect to bones
what is the joint in the full movement category?
synovial joints
what are the types of synovial joints (six)
gliding: allow for gliding or linear motion; carpals and tarsals
hinge: movement in a single axis, flexion and extension; elbow and knee
pivot: allow for rotational movement; C1 and C2 joint
condyloid: circumduction, flexion and extension; between the radius and carpals
saddles: between the trapezium and first metacarpal; makes thumb opposable
ball and socket: motion in any axis; hip and shoulder
describe the two main examples of ball and socket joints
the shoulder has a more shallow joint with more mobility and less stability, while the hip has a deeper joint with less mobility but more stability.
flexion/extension
decreasing joint angle/increasing joint angle
protonation/supination
palms down/palms up
internal/external rotation
rotation towards center of body/away from center of the body
plantarflexion/dorsiflexion
movement of feet or toes towards the ground/towards the shin
inversion/eversion
moving sole of the foot towards the midline/moving the foot away from the midline
protraction/retraction
movement anteriorly/movement posteriorly
adduction/abduction
movement toward the body/movement away from the body
