The anterior scalene muscle (Latin: scalenus anterior), lies deeply at the side of the neck, behind the sternocleidomastoid muscle.It arises from the anterior tubercles of the transverse processes of the third, fourth, fifth, and sixth cervical vertebrae, and descending, almost vertically, is inserted by a narrow, flat tendon into the scalene tubercle on the inner border of the first rib, and ...
The sternocleidomastoid muscle originates from two locations: the manubrium of the sternum and the clavicle. [4] It travels obliquely across the side of the neck and inserts at the mastoid process of the temporal bone of the skull by a thin aponeurosis. [4] [5] The sternocleidomastoid is thick and narrow at its center, and broader and thinner ...
They are located laterally to the transverse processes between prevertebral muscles from the medial side and vertebral (m. scalenus, m. levator scapulae, m. splenius cervicis) from lateral side. There is anastomosis with accessory nerve, hypoglossal nerve and sympathetic trunk. It is located in the neck, deep to the sternocleidomastoid muscle. [5]

The triangles of the neck describe the divisions created by the major muscles in the region.. The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck ...
Apex: Union of the sternocleidomastoid and the trapezius muscles at the superior nuchal line of the occipital bone. Anteriorly: Posterior border of the sternocleidomastoideus. Posteriorly: Anterior border of the trapezius. Inferiorly: Middle one third of the clavicle. Roof: Investing layer of the deep cervical fascia. Floor: (From superior to ...
It shortens and tightens muscles in the neck, which can lead to pain and cause tension headaches. Do these exercises to help stretch and strengthen the muscles that support your head and neck.
It surrounds the neck like a collar, it splits around the sternocleidomastoid muscle and the trapezius muscle. It is attached as; Posteriorly - Ligamentum nuchae; Anteriorly - Attached to the hyoid bone; Superiorly - (from backwards to forwards); External occipital protuberance and superior nuchal line of occipital bone; Mastoid process of ...
