Muscular system of the horse

Muscle fibers have bundles of myofibrils, which are all parallel to one another, and are able to contract due to actin and myosin.

In this case, they are classified according to whether they flex or extend the joints of the digit.

When they pass over a joint, they are protected in a tendon sheath, which contains synovial fluid as a lubricant.

The Coccygeus, Intertransversal caude[check spelling], Sacralcoccygeus ventralis, Sacral coccygeus dorsalis, Sacral coccygeus lateralis, Sacro-coccygeus ventralis raise and move the tail.
