- The point of buttocks is the highest point of the buttocks, formed by the sciatic tuber.
Chest and Breasts
- The breast or brisket is the area directly between the forelegs at the front of the abdomen, below the neck, formed by masses of muscles.
- The chest is the muscled area at the front of the horse, below the neck attachment, down to the legs.

Trunk and Tail
- The trunk refers to the area between the elbow and the flank.
- The ribs consist of 18 ribs.
- The abdomen or belly is the broad area underneath the horse between the elbow and the flank.
- The groins refer to the inner aspect of the thigh.
Forelimbs
- The shoulder region is the region of the scapula.
- The point of the shoulder is formed by the upper extremity of the humerus.
- The arm consists of massive muscles lying over the humerus.
- The elbow joint is a compound joint between the humerus, radius, and ulna.
- The point of elbow is the olecranon of the ulna.
- The forearm is the area between the elbow and the knee, formed from the radius and ulna.
- The axilla is the region inside the elbow.
Forelimbs (continued)
- The knee joint (carpus) is a complex joint formed by the radius, carpal, and metacarpal bones.
- The back tendons are in the forelimbs.
- The fore cannon is formed from the shank of the metacarpal bone.
- The fetlock and fetlock joint are the joint between the distal end of the large metacarpal bone and the first phalanxes with proximal sesamoids.
- The pastern region is the area above the coronet band and below the fetlock joint.
- The pastern joint is the joint between the 1st and 2nd phalanxes.
- The coffin joint is the joint between the 2nd and 3rd phalanxes with distal sesamoids.
- The coronet is the area at the bottom of the pastern where hair stops and hoof growth begins.
Hindlimbs
- The hip joint is the joint of the pelvis.
- The point of the hip is lying just forward and below the croup, formed by the external angle of the ileum (tuber coxae).
Head and Neck
- The ears are located on the top of the horse's head.
- The poll is the region between the two ears.
- The forelock is a tuft of hair that hangs between the ears.
- The fore head is the front part of the head.

- The jowl is the space between the branches of the lower jaw, just in front of the throat.
Eyes and Muzzle
- Each eye consists of an eyeball placed in the eye socket.
- The upper eye lid, lower eye lid, and third eye lid (nictitina) are parts of the eye.
- Eye lashes are also present.
- The muzzle is the region of the upper lip and nostrils (true and false).
Neck and Back
- The neck is the muscled area from the poll to the withers, attaching the head to the body.
- The crest is the upper part of the neck, where the mane grows.
- The mane is on the side of the neck.
- The jugular groove has two grooves running down the sides of the neck, above the windpipe.
Back Line
- The withers are the highest part of the trunk, where the height of the animal can be measured.
- The back (saddle region) is the area from behind the withers to the head of the last rib.
- The loins or lumbar region is the region of the lumbar vertebrae, extended from the head of the last rib to the external angle of the ileum.
- The croup is the region of the sacrum, extending from the highest part of the hip to the tail.
