Q

Example of a gliding joint

A

Clavicular joint, mid tarsal, mid carpal joints

17
Q

Example of ellipsoid joint

A

Phalanges joint ( knuckles)

18
Q

Function of a ball and socket joint

A

Movement in any direction

19
Q

Function of a hinge joint

A

Allows flexion and extension of an appendage eg elbow joint

20
Q

Function of a pivot joint

A

Rotation around an axis ( neck and forearms)

21
Q

Function of a saddle joint

A

Allows movement back and forth up and down, does not allow rotation ( thumb joint )

22
Q

Function of a gliding joint

A

Allow 2 bones to slide past each other ( mid tarsal, mid carpal )

23
Q

Function of an ellipsoid joint

A

Similar to ball and socket - lesser magnitude ( knuckle joint) metacarpophalangeal
