Describe how joints are classified. (270) | classified by the type of tissue that binds the bones at each junction
fibrous joints, cartilaginous joints, and synovial joints |
Describe the six types of synovial joints, and name an example of each type. (274) | ball and socket: shoulder, hip
condylar: between phalanges
plane: wrists and ankle
hinge: elbow
pivot: radius and ulna
saddle: thumb |
describe the movements permitted by each type of synovial joint (274) | ball and socket: all planes, including rotation
condylar: no rotation
plane: sliding or twisting
hinge: flexion and extension
pivot: rotation
saddle: variety in mainly two planes |
rotation | around an axis (twisting head side to side) |
supination | rotation of the forearm so the palm is upward |
extension | straightening the knee |
eversion | turning foot so plantar surface faces laterally |
protraction | moving the head forward |
flexion | bending the knee |
pronation | rotation of the forearm so the palm is downward |
abduction | moving a part up (moving arm up to make right angle with body) or spreading of fingers and toes |
depression | lowering a part or drooping the shoulders |
adduction | moving a part back towards midline (moving right angle back down) or moving the fingers and toes closer together |
