2023年11月3日 · The scalenus anterior muscle is the anteriormost of the three scalene muscles. It originates from the anterior tubercles of transverse processes of the vertebrae C3-C6. The muscle takes an inferior, almost vertical, course towards the thoracic cage.

2024年11月25日 · The scalene muscles are three paired muscles (anterior, middle and posterior) located in the lateral aspect of the neck. They form part of the floor of the posterior triangle of the neck. The scalenes act as accessory muscles of respiration and perform flexion at the neck.

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. It is located between the subclavian vein and the subclavian artery.

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).

Discover the anatomy, function, and importance of the scalenus anterior muscle, from its origin and insertion to its role in neck and rib movement.

Origin: The scalenus anterior muscle originates from the transverse processes of the third to sixth cervical vertebrae, specifically the anterior tubercles. Insertion: The muscle inserts onto the scalene tubercle of the first rib. Muscle Path: The scalenus anterior muscle courses obliquely downwards and medially from its origin on the cervical ...

The Scalenus anterior (Scalenus anticus) lies deeply at the side of the neck, behind the Sternocleidomastoideus.
