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 term navicular bone or hand navicular bone was formerly used for the scaphoid bone, [1] one of the carpal bones of the wrist. The navicular bone in humans is located on the medial side of the foot, and articulates proximally with the talus, distally with the three cuneiform bones, and laterally with the cuboid.
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.
Strictly these should be termed the proximal sesamoid bones whereas the navicular bone should be referred to as the distal sesamoid bone. The patella is also a form of sesamoid bone in the horse. Although many carnivores have radial sesamoid bones, [16] the giant panda and red panda independently evolved to have an enlarged radial sesamoid bone.
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).
Navicular syndrome, often called navicular disease, is a syndrome of lameness problems in horses. It most commonly describes an inflammation or degeneration of the navicular bone and its surrounding tissues, usually on the front feet.
Points of a horse. Equine anatomy encompasses the gross and microscopic anatomy of horses, ponies and other equids, including donkeys, mules and zebras.While all anatomical features of equids are described in the same terms as for other animals by the International Committee on Veterinary Gross Anatomical Nomenclature in the book Nomina Anatomica Veterinaria, there are many horse-specific ...
The central tarsal bone in equids is commonly called the "navicular" bone only by anatomists (denoted as the "true" navicular or scaphoid bone by vets) as it is analogous to the similarly named bone in humans but veterinarians and the majority of horse owners call the distal sesamoid bone the navicular bone (mentioned in this source). My guess ...
