The longus colli muscle (Latin: musculus longus colli) is a muscle of the human body located in the neck. It is part of the prevertebral muscles group and plays a crucial role in the movement and stabilization of the cervical spine.

Anatomy[edit | edit source]

The longus colli muscle is divided into three parts: the superior oblique part, the vertical part, and the inferior oblique part.

Origin and Insertion[edit | edit source]

Innervation[edit | edit source]

The longus colli muscle is innervated by branches from the cervical plexus, specifically from the C2 to C6 spinal nerves.

Blood Supply[edit | edit source]

The muscle receives its blood supply from the vertebral artery.

Function[edit | edit source]

The primary function of the longus colli muscle is to flex the neck and assist in its rotation. It helps in stabilizing the cervical spine and maintaining posture.

Clinical Significance[edit | edit source]

Injury or strain to the longus colli muscle can result in neck pain and reduced mobility. Conditions such as whiplash can affect this muscle, leading to discomfort and the need for medical intervention.
