In the front of the leg, the only thing covering the bones is skin, the extensor tendons (which are very flat) and the suspensory ligaments and fascia. The splint bones are also known as the 2nd and 4th metacarpal and fused 25 - 35 million years ago during the time of the Miohippus. Bog spavins are unsightly, but many horses perform well despite them. Approximately 35 million years ago, a global drop in temperature created a major habitat change, leading to the transition of many forests to grasslands. Structural defects, as well as other problems such as injuries and infections, can cause lameness, or movement at an abnormal gait. Some breeds like the Appaloosa have very sparse manes, while others like Morgans and some draft breeds have very thick manes.

Beneath the surface of the skin are the upright ‘fins’ of the vertebrae. Although it does not usually cause lameness or other problems, prolonged periods of stocking up can lead to other skin issues. Horse Anatomy. It is the next joint down from the knee on the front legs and the hocks on the back legs. The triceps muscle straightens the elbow and foreleg, running from the elbow to the bottom of the shoulder blade. The original ancestors of horses had shorter legs, terminating in five-toed feet. Leg parts. The hock joint is the largest joint on the horse's hind legs. Quiz: Horse Body Parts … Some breeds like Morgans, Arabians, some warmbloods, draft horses, and ponies have a more distinctively crest than breeds like Quarter Horses and Thoroughbreds. While the horse uses muscles throughout its body to move, the legs perform the functions of absorbing impact, bearing weight, and providing thrust. Manes provide some protection from the weather. Foals raised by humans have a better chance for survival, as there are therapeutic treatments that can improve even major conformation problems. A horse's nostrils are very flexible. Stocking up is an issue that occurs in horses that are held in stalls for multiple days after periods of activity. It is frequently caused by pain to the shoulders, hips, legs or feet. The same portion in the hind limbs consists of the major muscles, ligaments and tendons, as well as the reciprocal joints of the hock and stifle.[14]. A horse's eyes are set slightly on the side of its head. The hoof is arguably one of the most important horse body parts. The hollow above the eyes is the sub-orbital depression. While horses with poor conformation and congenital conditions are more likely to develop lameness, trauma, infection and acquired abnormalities are also causes. A. Tibia.

After the pelvis come the femur (thigh), patella, stifle joint, tibia, fibula, tarsal (hock) bone and joint, large metatarsal (cannon) and small metatarsal (splint) bones. Horse Body Parts Trivia Questions! [6] Although having a small range of movement, the proximal interphalangeal joint (pastern joint) is also influential to the movement of the horse, and can change the way that various shoeing techniques affect tendons and ligaments in the legs.

The ulna shrank in size and its top portion became the point of the elbow, while the bottom fused with the radius above the radiocarpal (knee) joint, which corresponds to the wrist in humans. The shoulder is the large bone that runs from the withers down to the chest. This joint although it may appear so, is not actually analogous to the human ankle. Movement adds concussive force to weight, increasing the likelihood that a poorly built leg will buckle under the strain. Some causes for this condition may be minor and some may be more serious. Any bones below the forearm on a horse are essentially equivalent to the bones of the hands and feet on humans. Pricked forward ears means it is interested in what it sees or hears. [17], The forelegs carry the majority of the weight, usually around 60 percent, with exact percentages depending on speed and gait. The legs of a horse used for cutting, in which quick starts, stops and turns are required, will be shorter and more thickly built than those of a Thoroughbred racehorse, where forward speed is most important. The synovial joint consists of two bone ends covered by articular cartilage. Some warmbloods have convex or almost “Roman noses”. Horses also have a unique anatomical feature called the stay apparatus, which allow… [19], Lameness in horses is movement at an abnormal gait due to pain in any part of the body. Arabians often have a concave or dished face. No legs, no horse. [13] The suspensory apparatus consists of the suspensory ligament, the check ligament, the deep digital flexor tendon, the superficial flexor tendon, the common digital extensor tendon and the sesamoid bones. The angles of certain bones, especially in the hind leg, shoulders, and pasterns, also affect movement. Beneath the skin is cartilage. [15], A sequence of movements in which a horse takes a step with all four legs is called a stride. These changes were first seen in the genus Merychippus, approximately 17 million years ago. The question is - how much do you remember from your 4-H days? The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons, and ligaments that support the weight of the equine body. The underlying bones are the tibia and the smaller fibula which are equivalent to our calf and shin bones. The withers are at the top of the shoulder where the neck joins the body. Occasionally, you may hear the fetlock joint referred to as the pastern joint or ankle. When you talk about horses, evaluate their conformation, or work with them, it's essential that you know how to identify and say or write the correct words for each part. Injuries to and problems with horse legs can be relatively minor, such as stocking up, which causes swelling without lameness, or quite serious. Parts of the Horse. Lower leg parts. [27] A shoe boil is an injury that occurs when there is trauma to the bursal sac of the elbow, causing inflammation and swelling. The articular cartilage is smooth and resilient and enables frictionless movement of the joint. [23], "Form to function" is a term used in the equestrian world to mean that the "correct" form or structure of a horse is determined by the function for which it will be used. This angle allows the hind legs to flex as weight is applied during the stride, then release as a spring to create forward or upward movement. [22] The range of motion and propulsion power in horses varies significantly, based on the placement of muscle attachment to bone. Large differences in bone structure and size can be found in horses used for different activities, but correct conformation remains relatively similar across the spectrum. This bone extends from beneath the structures of the knee to the fetlock joint below. Along either side are many muscles. In this area are many nerve endings and acupressure points. The upper bone is longer and the shorter lower bone extends into the hoof where it joins to the pedal bone inside.
