The function of the medial deltoid is abduction of the shoulder joint. That means it lifts your upper arm up and out to your side. The posterior deltoids are located on the back of your shoulders. They have the opposite functions of the anterior deltoid: extension, horizontal extension, and external rotation of the shoulder joint. The triceps brachii muscle is the muscle caudal to humerus and shoulder joint, that fills the triangle between the caudal border of the scapula, the humerus and the olecranon.Its caudal border (margo tricipitalis) extends from the olecranon into the direction of the withers and is clearly visible under the skin in the live animal.The triceps brachii possesse three heads of origin, and in the In addition to these two large muscles, a small muscle called the plantaris runs between your gastrocnemius and soleus down the length of your lower leg. Providers call these three muscles the triceps surae. But not everyone has a plantaris muscle. About 10% of people only have the two larger muscles. What does the calf muscle look like?
Cervical nerves are spinal nerves that arise from the cervical region of the spinal cord. These nerves conduct motor and sensory information via efferent and afferent fibers, respectively, to and from the central nervous system. While classified as peripheral nerves, the motor cell body resides in the anterior horn of the spinal cord. There are eight pairs of cervical nerves, denoted C1 to C8

Function. The axillary nerve has both a motor and a sensory distribution of innervation. It has motor fibres that innervate the deltoid muscle, acting as an abductor, flexor and extensor at the shoulder joint, as well as the teres minor muscle, allowing lateral rotation of the glenohumeral joint.; As mentioned above, it has sensory innervation to the skin of the arm superficial to lower part YIz50CB. 215 13 414 265 481 37 17 126 16
