The English name for this muscle is the straight muscle of the head at the side. The word rectus is Latin for “straight.”�The word capitis comes from the Latin caput meaning “head.”�Lateral is from the Latin latus meaning “side.” [1]
Origin
[edit | edit source]
Superior surfaces of the transverse processes of the atlas [2]
Insertion[edit | edit source]
Inferior surface of the jugular process of the occipital bone [3]
Nerve Supply[edit | edit source]
Anterior primary rami of the first cervical spinal nerve (C1)
Blood Supply[edit | edit source]
The muscle receives blood from the ascending cervical artery, which is a small branch of the inferior thyroid artery from the thyrocervical trunk of the subclavian artery. It also receives blood from the muscular branches of the vertebral artery. The muscle also receives small muscular branches from the occipital artery as it passes it lateral aspect. [4]
Action[edit | edit source]
- Stabilizes the head
- Weakly assists with lateral flexion of the head [5]
Clinical Relevance[edit | edit source]
