This ligament allows dogs to carry their heads while running long distances, such as while following scent trails with their nose to the ground, without expending much energy. [8] In horses, the parasite Culicoides can spread onchocerca cervicalis by living in the nuchal ligament, causing dermatitis. [9]
Ligaments of the upper body include: Nuchal and supraspinous ligaments: the nuchal ligament is composed of strong elastic tissue originating from the occipital protuberance of the skull (the poll) and extending to the withers. The main (funicular) portion has attachments on the second cervical vertebra, and the flattened fanlike (lamellar ...
A draft horse sleeping while standing up. The stay apparatus is an arrangement of muscles, tendons, and ligaments that work together so that an animal can remain standing with virtually no muscular effort. [1] It is best known as the mechanism by which horses can enter a light sleep while still standing up. [2]
Splenius: originates from the 3rd-5th thoracic vertebrae, the dorsal scapular ligament, and the nuchal ligament. Inserts on the nuchal crest, the atlas, and the 3rd-5th cervical vertebrae. Sternocephalicus: originates from the cariniform cartilage of the sternum, inserts into the caudal side of the mandible. Lowers the head.
The Supraspinous ligament is a continuation of the nuchal ligament, which begins at the poll and inserts on the withers. The supraspinous ligament attaches to the tops of the remaining thoracic and lumbar vertebrae. These two ligaments in combination provide a link throughout the topline of the horse, aiding in the elastic movement of the body.
However, microscopic examination in necropsy has shown DSLD horses can not only be affected in the tendons and ligaments of all legs and the patella, but can have affected tissues in the nuchal ligament, eyes, aorta, skin and fascia, lungs and other organs, as well as ligaments and tendons throughout the body. Because of its systemic nature ...
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. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus , which locks major joints in ...
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 ...
