The triceps run along the humerus (the main bone of the upper arm) between the shoulder and the elbow. Along with the biceps, it enables extension and retraction of the forearm. drawing the lip downward. mandible bone. lower lip. epicranius. raising eyebrows, wrinkling forehead, pulling scalp posteriorly. frontal belly, occipital belly, temporal bone. skin of brow, epicranial aponeurosis. lateral pterygoid. protruding the mandible, opening the jaw, moving the mandible outward and right and left. Muscles being discussed: Triceps Location: The Triceps are located in the horses shoulder. These muscles originate and insert at different places along the scapula, humerous, and olecranon (elbow). Function: Extends elbow, flexes shoulder. Symptoms of tension/Injury: · Lameness · Toe dragging · Reluctance to extend foreleg · Soreness in muscle · Shortened stride · Reluctance going The biceps brachii (BB), commonly know as the biceps, is a large, thick muscle on the ventral portion of the upper arm.. The muscle is composed of a short head and a long head. The long head is located on the lateral side of the biceps brachii while the short head is located on the medial side.. The biceps brachii works across three joints, and is able to generate movements in glenohumeral Biomechanics of the Elbow. Kai-Nan An, Bernard F. Morrey, in Morrey's the Elbow and its Disorders (Fifth Edition), 2018. Extensors. The medial heads of the triceps and anconeus muscles were found to be active during extension; the lateral and long heads of the triceps acted as auxiliaries. 73 The anconeus was also active during resisted pronation and supination. Motor neurons integrate signals from the brain to the muscles, glands, and organs that intend to carry out the required motor function. Motor neurons allow us to move, talk, eat, swallow, and breathe; therefore, without these cells, we would be unable to complete many basic life functions. There are two types of motor neurons: Lower motor .
