Feb 10, 2025 · The anterior scalene muscle is located deep to the sternocleidomastoid on the lateral aspect of the neck.

Function: Elevation of the first rib.

The scalene muscles are a group of three muscles on each side of the neck, identified as the anterior, the middle, and the posterior. They are innervated by the third to the eighth cervical spinal nerves (C3-C8).

The anterior scalene, AKA scalenus anterior (scalenus anticus; Latin: musculus scalenus anterior) muscle is one of the lateral muscles of the neck, belonging to the scalene group. It is deeply placed, lying behind the Sternocleidomastoid .

Scalene are a group of three pairs of muscles in the lateral neck: scalenus anterior, scalenus medius and scalenus posterior. Sometimes a fourth muscle, the scalenus minimus is present behind the lower portion of the scalenus anterior.

Insertion: Scalene tubercle and cranial crest of first rib Action: Flexion of the cervical spine, Lateral flexion of the cervical spine, rotation of the cervical spine, Elevation of the first rib Innervation: Anterior branches of the cervical nerves C5 to C7.

Jul 22, 2022 · The scalenus anterior (also known as anterior scalene) muscle is a neck muscle, one of the three scalene muscles and known as the "key" structure for the thoracic inlet as it is an important anatomical landmark.
