The neck muscles, including the sternocleidomastoid and the trapezius, are responsible for the gross motor movement in the muscular system of the head and neck. they move the head in every direction, pulling the skull and jaw towards the shoulders, spine, and scapula. working in pairs on the left and right sides of the body, these muscles.
Superficial Muscles Of The Head And Neck Anterolateral View Diagram A large group of muscles in the cervical area, responsible for the movement of the head in all directions. anterior muscles of the neck. superficial muscles: platysma, sternocleidomastoid. suprahyoid muscles: digastric, mylohyoid, geniohyoid, stylohyoid. infrahyoid muscles: sternohyoid, sternothyroid, thyrohyoid, omohyoid. These muscles give the sides of the neck their shape. although anchored in the neck, their primary functions are to move the shoulder blades and support the arms. in the front of the neck, the. Superficial muscles of the neck include: sternocleidomastoid (scm): a long, slender muscle that travels from the breastbone (sternum) to the collarbone (clavicle) and then on a diagonal up to the base of the skull. this muscle side bends, rotates, and bends the neck forward. scalenes (anterior, middle, and posterior): a group of three muscles. Sternocleidomastoid: this large neck muscle helps rotate the head upward and side to side. the muscles of the face overlap and crisscross over each other, creating a mask of muscle over the skull.

Conclusion. our neck muscles are involved in the important actions of both moving and supporting our head in space. some neck muscles also support the critical action of breathing when we need extra breath. in this article, we’ve covered the attachments and actions of the superficial and mid layer neck muscles. 2. correlate the gross anatomy with palpable soft tissues of the neck. 3. identify the superficial and deep muscles of the anterior triangle of the neck. volume 4 head & neck 4.4.7 muscles acting on the hyoid bone 4.5.7 infrahyoid muscles, thyroid gland 4.8.12 glossopharyngeal and vagus nerves 4.8.13 accessory and hypoglossal nerves.
