Bones of the Dog Leg

The bones of the dog anatomy leg can be divided into three sections:

  1. The shoulder joint: This joint connects the leg to the body. The bones that make up the shoulder joint are the scapula (shoulder blade), the humerus (upper arm bone), and the radius and ulna (forearm bones).

  2. The elbow joint: This joint connects the upper arm to the lower arm. The bones that make up the elbow joint are the humerus, the radius, and the ulna.

  3. The carpus (wrist) joint: This joint connects the forearm to the paw. The bones that make up the carpus joint are the radius, the ulna, and the carpal bones.

  4. The metacarpus (pasture) joint: This joint connects the wrist to the toes. The bones that make up the metacarpus joint are the metacarpal bones.

  5. The phalanges (toes) joint: This joint connects the pasterns to the toes. The bones that make up the phalanges joints are the phalanges bones.

Muscles of the Dog Leg

The muscles of the dog anatomy leg are responsible for moving the leg.

  • The muscles that move the shoulder joint are the deltoids, the triceps, and the biceps.
  • The muscles that move the elbow joint are the brachioradialis, the triceps, and the anconeus.
  • The muscles that move the carpus joint are the flexor carpi radialis, the flexor carpi ulnaris, and the extensor carpi radialis.
  • The muscles that move the metacarpus joint are the extensor digitorum communis, the flexor digitorum profundus, and the flexor digitorum superficialis.

Ligaments of the Dog Leg

The ligaments of the dog anatomy leg help to hold the bones in place.
