Like Seeleys essentials of anatomy physiology ( etc.)? Role of muscles . A coexisting unilateral absence of SCM with the ipsilateral absent trapezius is an extremely rare variation and till date, only about three such reports are present in literature .Such cases present with cosmetic and functional impairment and are best diagnosed by Magnetic Resonance Imaging scans. The sternocleidomastoid (right muscle shown) can be clearly observed when rotating the head. The movement of troponin and tropomyosin is key in facilitating the myosin head to move along the thin filament, resulting in a contraction of the sternocleidomastoid muscle. The sternocleidomastoid muscle (SCM) is an important landmark in the neck which divides it into an anterior and a posterior triangle. The SCM is a unique muscle, in terms of variations at its origin.4,5,6 Also, it has a variable innervations arrangement, the classical anastomotic pattern being observed in 50% of the cases.These anatomical details have a pivotal role in the planning of pedicle muscle flaps in reconstructive surgeries.

The muscle primarily responsible for a movement is called the prime mover, and muscles that assist in this action are called synergists. On either side, the SCM diagonally divides the neck musculature into anterior (front) and posterior (back) triangles. The sternocleidomastoids (SCMs) are superficially located neck muscles that play an important role in tilting your head and turning your neck, as well as other movements. ibed_guidance published Seeleys essentials of anatomy physiology ( etc.) What is the antagonist muscle in elbow flexion?

English Edition. Antagonist: tensor fascia latae To explain skeletal muscle movements as activities of agonists (prime movers), antagonists, and synergists. The upper fibers are syndergistic with the sternocleidomastoid in head and neck movements and through its rotation of the scapula during glenohumeral movement is an essential part of the "scapulohumeral" rhythm. It travels superiorly, laterally, and posteriorly. Antagonist: Gluteus maximus The accessory nerve nucleus is in the anterior horn of the spinal cord around C1-C3, where lower motor neuron fibers mark its origin. Innervation is when an organ or body part is supplied with nerves. During elbow flexion where the bicep is the agonist, the tricep muscle is the antagonist.
