Sesamoid bones: Bones embedded within a tendon. The horse's proximal digital sesamoids are simply called the "sesamoid bones" by horsemen, his distal digital sesamoid is referred to as the navicular bone. Ligaments and tendons hold the skeletal system together. Ligaments hold bones to bones and tendons hold bones to muscles.
The following tendons are the main tendons found in the lower leg. When they pass over a joint, they are protected in a tendon sheath, which contains synovial fluid as a lubricant. Common digital extensor: the common digital extensor muscle becomes tendon in the bottom third of the radius and continues down the front of the leg. The tendon ...
The coffin bone. The hoof of the horse contains over a dozen different structures, including bones, cartilage, tendons and tissues. The coffin or pedal bone is the major hoof bone, supporting the majority of the weight. Behind the coffin bone is the navicular bone, itself cushioned by the navicular bursa, a fluid-filled sac.
Bones are connected to muscles via tendons and other bones via ligaments. Bones are also used to store minerals, and are the site of red blood cell formation. The Appendicular system includes the limbs of the horse; The Axial system is composed of the spine, ribs and skull;
Sagittal section of a wild horse hoof. Pink: soft tissues; light gray: bones (P2, P3 and navicular bone); cyan: tendons; red: corium; yellow: digital cushion; dark gray: frog; orange: sole; brown: walls) The third phalanx (coffin bone; pedal bone; P3;) is completely (or almost completely) covered by the hoof capsule. It has a crescent shape and ...
There are between one and four sesamoid bones associated with the stifle joint in different species. These sesamoids assist with the smooth movement of tendon/muscle over the joint. The most well-known sesamoid bone is the patella, more commonly known as the "knee cap". It is located cranially to the joint and sits in the trochlear groove of ...
The skeletal system of a modern horse. The horse skeleton averages 205 bones. [60] A significant difference between the horse skeleton and that of a human is the lack of a collarbone—the horse's forelimbs are attached to the spinal column by a powerful set of muscles, tendons, and ligaments that attach the shoulder blade to the torso. The ...
A skeleton is the structural frame that supports the body of most animals.There are several types of skeletons, including the exoskeleton, which is a rigid outer shell that holds up an organism's shape; the endoskeleton, a rigid internal frame to which the organs and soft tissues attach; and the hydroskeleton, a flexible internal structure supported by the hydrostatic pressure of body fluids.
