1. Muzzle - The part of the head which includes the nostrils, lips, and the bones, gums, and teeth covered by latter.
2. Nostril - Large nostrils allow for the intake of large quantities of air, especially while running. Horse also use scent to help identify people, animals and objects. Objects that are too close to a horse’s face to see will probably get a thorough sniffing. Some horses display their emotions with the nostrils. Some horses will wrinkle their nose in disgust. Entrance to the respiratory system.
3. Cheek - The wide flat area on the side of the face is the cheek, with the rim of the bone curved along the bottom. Also Known As: cheek bone, jowl.
4. Face - The front part of the head.
5. Eye - In which a horse can see. Horses have dichromic vision, meaning they have a fundamentally different view of the world to people.
6. Forelock - A lock of hair that grows from or falls on the forehead, the part of a horse's mane that falls forward between the ears.
7. Ears - In which to hear. Is a primary sourse of noticing a horses behavior in also, what it is thinking or listening towards something.
8. Poll - The poll is the area immediately behind the ears and the underlying bones are the top of the skull bone and the atlas bones of the neck. In this area are many nerve endings and acupressure points. The poll area is where the bridle path, if one is clipped, begins. On some horses the poll is quite flat, while on others it may be more prominent.
9. Mane - The long coarse hair that grows from the crest of the neck.
10. Crest - The crest is the topline of the neck. Ideally the crest should be a gentle convex curve from the poll to the withers. On a very fat horse the crest can be very thick, and almost seem to flop over. On a very thin horse the crest will be straight and thin. Some breeds like Morgans, Arabians, some warm bloods and draft horses and ponies have a more distinctively crest than breeds like Quarter Horses and Thoroughbreds.
11. Withers - The withers are at the top of the shoulder where the neck joins the body. The ‘lump’ seen on many horses is the top of the spiny process of the tallest thoracic vertebrae. This part of the vertebrae is quite high on some horses and shallow on others.
12. Back - Part of the horse where the saddle is laid upon.
13. Loin - The region where the back ends is the loin. This can be a very sensitive area on some horses. The horse would buck if you slid back and sat on its loins.
14. Croup - The croup is the area from the highest point of the hindquarters to top of the tail.
15. Dock - The area at the top of the tail is called the dock. Below the skin are muscles and the extension of the vertebrae from the spine. There are about 15 small vertebrae that make up the bone structure of the tail. The muscles through the dock and tail make the tail very mobile for both expressing mood, balancing, and swishing away insects.
16. Buttock - Fleshy part under the tail.
17. Thigh - Upper part of the rear leg.
18. Tail - Extension of the spinal column in which long hair grows from.
19. Stifle - Part of the leg of a horse between the thigh and the kneecap. The stifle joint is both very large and very complex in structure.
20. Gaskin - The part of the hind leg of a horse or related animal between the stifle and the hock.
21. Hock - Point of the part of the gaskin behind the knee.
22. Chestnuts - Also known as a night eye, is a callousity on the body of a horse or other equine, found on the inner side of the leg above the knee on the foreleg and, if present, below the hock on the hind leg.
23. Cannon Bone - The greatly developed middle metacarpal or metatarsal bone of hoofed quadruped mammals, extending from the hock to the fetlock.
24. Fetlock - The fetlock is formed by the joint between the canon bone and the longer pastern bone. At the back of the fetlock lies a small bone called the sesamoid. Occasionally, you may hear the fetlock joint referred to as the pastern joint or ankle.
25. Pastern - Part of the horse that corresponds to the first phalange. The pastern is made up of two bones that extend downwards from the fetlock. The upper bone is longer and the shorter lower bone extends into the hoof where it joins to the pedal bone inside.
26. Coronet Band - Upper part of a horse's hoof. The ring of soft tissue just above the horny hoof that blends into the skin of the leg
27. Hoof - Developed nail that enclosed the end of the toes of a horse.
28. Point Of Hip - Joint connecting the rear leg to the pelvis.
29. Sheath - The pocket of skin that protects the penis of the horse.
30. Flank - The slightly indented area behind the area of the barrel is the flank. This is the area you watch to count your horse’s respiration. If the flank appears unusually sunken this can mean your horse is dehydrated.
31. Ribs - Integral to the back structure is the rib cage, which also provides support to the horse and rider. Here you can tell if a horse is underweight by thier ribs showing.
32. Heart Girth - The measurement taken around the horse's barrel just behind the front legs.
33. Elbow - The joint of the front leg at the point where the belly of the horse meets the leg.
34. Shoulder - Made up of the scapula and associated muscles, runs from the withers to the point of shoulder (the joint at the front of the chest, i.e. the glenoid); the angle of the shoulder has a great effect on the horse's movement and jumping ability, and is an important aspect of equine conformation.
35. Point Of Shoulder - The shoulder should be long, sloping, and muscular. It should extend well into the back.
36. Arm - Front leg coming from the shoulder.
37. Forearm - The area of the front leg between the knee and elbow, consisting of the fused radius and ulna, and all the tissue around these bones; anatomically, the antebrachium.
38. Knee - The carpus of the horse (equivalent to the human wrist), the large joint in the front legs, above the cannon bone.
39. Chest - When viewed from the front the chest of the horse should be well defined and not blend into the bottom of the neck. The width of the chest is defined by the structure of the bone beneath it.
40. Throat Latch - The point at which the windpipe meets the head at the underside of the jaw, corresponding to where the eponymous part of a bridle goes.
41. Chin Groove - The part of the horse's head behind the lower lip and chin, the area that dips down slightly on the lower jaw; area where the curb chain of certain bits is fastened.
42. Neck - Part of the horse between the head, the withers and the chest.
