Function. Due to the muscle's close proximity to the shoulder joint, most movements of the upper arms involve the triceps to some degree. The proximity of this muscle to the shoulder also makes it a supporting muscle for the rotator cuff, so if you're worried about shoulder injuries, working out this muscle won't hurt. There are 6 MSR that are commonly tested and will be the focus of this article: biceps, triceps, brachioradialis, knee, ankle, and jaw jerk. Anatomy and Physiology The first 5 MSR listed above; however not the jaw jerk, occur when stretch receptors within the muscle are activated; the clinician taps a part of the body to create a small amount Identify the movement and function of the pectoral girdle and upper limbs; The forearm flexors include the biceps brachii, brachialis, and brachioradialis. The extensors are the triceps brachii and anconeus. The pronators are the pronator teres and the pronator quadratus, and the supinator is the only one that turns the forearm anteriorly The primary function of the triceps is the extension of the elbow joint. It is composed of three heads (tri = three, cep = head): a long head, a lateral head, and a medial head. The tendons all have different origins, but the three heads combine to form a single tendon distally. The latissimus dorsi muscle is a broad, flat muscle that occupies the majority of the lower posterior thorax.The muscle's primary function is of the upper extremity but is also considered to be a respiratory accessory muscle.. Along with the levator scapulae, trapezius and rhomboid muscles, the latissimus dorsi belongs to the superficial layer of the extrinsic back muscles. Many functions of the spinal cord are also executed independently from the brain, such as a spinal reflex. The definition of a spinal reflex as well as their components, functions, pathways, and physiology will be described in this article and is a must-know for every student that is passionate about neurosciences.
