name the 6 types of joints
condylar gliding hinge pivot spheroidal suture
suture joint
immovable joint, bones interlock
1. skull - cranial bones
spheroidal joint
rounded end of bone articulates with cup-shaped socket
- shoulder
- hip
pivot joint
permits rotation of one bones around the other
- wrist (radius/ulna)
- neck (atlas/axis)
hinge joint
concave surface articulates with convex surface
- elbow
- finger
- toe
gliding joint
flat/slightly curved surfaces, gliding movement
- wrist (carpals)
- ankles (tarsals)
condylar
two knuckle shaped surfaces articulate with a concave surface
1. knee (femur, tibia)
flexion
bending at a joint, decrease in of angle of joint
extension
straightening of a joint resulting in an increase of angle of joint
abduction
move appendage away from midline of the body
adduction
move appendage toward the midline of the body
supination
to turn the palm upward
pronation
turn the palm downward
dorsiflexion
flexing foot upward
plantar flexion
