The Peculiarities Of The Front Limb Muscles At Muskrat (Ondatra Zibethica)

摘要

The study conducted by the dissection on the front limb muscles at muskrat has showed to develop muscle mass and its insertions in conjunction with the development of the prominences and bone depressions that appear followed the muscle action. Thus, ones can signal the development of the brahiocefalic muscle consists of m. cleidobrahial, m. clido-mastoidian and m. cleidooccipital, muscles with effective involved in the chest member abduction. On the other hand, there is development deltoid muscle with its three parts: scapularis, acromialis and clavicularis, inserted on the deltoidal ridge extremely deployment, the muscles that act as powerful abductor of the arm.Forearm muscles are remarkable by muscle belly that is developed with the short and strong tendons. The pronation and supination are favored to form ligament structures of elbow joints are produced by muscles pronator teres, m. pronator quatratus and m. supinator. They are developing, demonstrating the high efficiency of switching from pronation to supination and vice versa..
