a). Forelimb / arm / front legs / humerus – upper arm / ulna and radius lower arm / scapula – shoulder / pectoral girdle
b). K – scapula
M – Humerus.
N – Ulna
P- Radius
c).
- has a ridge or coracoids process for increasing surface area for muscle attachment
- broad, wide or flattened for increasing surface are for muscle attachment
- has a socket, cavity or glenoid cavity or depression for articulation with next bone humerus or head of humerus
- has cartilage to make it smooth
- a smooth surface of the socket for reducing or minimizing friction.
d). Proximal end – ball and socket
Reason
- head shaped like a ball / ball like rounded head / round head , allow movement in more that one plane
Distal end – hinge joint
Reason:
Allow movement in only one plane / presence of a grove / olecranon process / presence of condl / trochlea which articulates with sigmoid notch
e). attachment of musles / tendons formation of hinge jpint, prevent overstretching of forearms backwards allow movement in only one plane
