In equine anatomy, the term sesamoid bone usually refers to the two sesamoid bones found at the back of the fetlock or metacarpophalangeal and metatarsophalangeal joints in both hindlimbs and forelimbs. Strictly these should be termed the proximal sesamoid bones whereas the navicular bone should be referred to as the distal sesamoid bone. The ...
The vertebral column consists of irregular bones. 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 ...
Skeleton of the lower forelimb. Each forelimb of the horse runs from the scapula or shoulder blade to the third phalanx (coffin or pedal) bones. In between are the humerus (arm), radius (forearm), elbow joint, ulna (elbow), carpus (knee) bones and joint, large metacarpal (cannon), small metacarpal (splint), sesamoid, fetlock joint, first phalanx (long pastern), pastern joint, second phalanx ...
A fetlock (a MCPJ or a MTPJ) is formed by the junction of the third metacarpal (in the forelimb) or metatarsal (in the hindlimb) bones, either of which are commonly called the cannon bones, proximally and the proximal phalanx distally, commonly called the pastern bone. Paired proximal sesamoid bones form the joint with the palmar or plantar ...
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 suspensory apparatus, including the superficial and deep digital flexor tendons along with the proximal and distal check ligaments. [1] The distal sesamoidean ligaments run from the sesamoid bones to the two pastern bones. Biceps brachii: originates from the caudal side of the scapula and inserts into the radial tuberosity.
The pastern is a part of the leg of a horse between the fetlock and the top of the hoof.It incorporates the long pastern bone (proximal phalanx) and the short pastern bone (middle phalanx), which are held together by two sets of paired ligaments to form the pastern joint (proximal interphalangeal joint).
Fetlock is the common name for the metacarpophalangeal and metatarsophalangeal joints of horses, is a rotatory joint that can exhibit the greatest range of motion of any equine joint. [3] The fetlock joint is formed between the large metacarpal or metatarsal bone ( in the hindlimb and forelimb) and the proximal sesamoid bones. [4] Relation with ...
