Longus Colli Muscle Anatomy
Table of Contents
What is Longus Colli Muscle?
- Longus Colli is a paired muscle situated on the anterior surface of the vertebral column. As such, it is often known as anterior prevertebral muscle along with the longus capitis, rectus capitis anterior, or the scalenus anterior muscles. The longus colli muscle (‘long muscle of the neck) is also called as longus cervicis since it spans the entire cervical spine or the 1st 3 thoracic vertebrae. By working on the cervical vertebrae, longus Colli is responsible for forwarding or the lateral flexion of the neck, as well as the rotation of the neck.
Relations of the Longus Colli Muscle
- Longus Colli, or all prevertebral muscles, are situated deeper in the prevertebral fascia, which is a layer of the deeper cervical fascia of the neck. The muscle locates in the groove created by the pathway of the transverse process with the vertebral body, posterior to the retropharyngeal space. Therefore, the esophagus, trachea, thyroid gland, or the muscles of the hyoid (supra-, infra-) are all located anterior to it. Longus Colli is bordered medially by the cervical plexus, brachial plexus, or the subclavian artery.
- The medial border of the scalenus anterior muscle is located next to the lateral border of the longus Colli. Here, a pyramidal space is created, with the 1st section of the subclavian artery creating its base. The thoracic duct, cervical sympathetic trunk, or the 1st part of the vertebral artery (V1) are all located within this pyramidal space, crossing between the longus Colli or the scalenus anterior muscles. The cervicothoracic ganglion is also located lateral to the longus Colli muscle at the level of the 7th cervical vertebra.
- Posterior to longus Colli, 1 can find the carotid artery (including the carotid sheath) or the phrenic nerve. These are located anterosuperiorly to the tubercle of the transverse process of the 6th cervical vertebra. In addition, the inferior thyroid artery follows a medial course inferior to this tubercle or then descends nearer to the longus Colli muscle towards the thyroid gland.
- The beginning of the vertical or the inferior parts of the longus Colli represents the deeper structures of the superior mediastinum.
Origin
- Longus Colli travels the entire length of the neck; between the atlas (1st cervical vertebra) or the T3 (3rd thoracic vertebra). It is narrow at its superior or the inferior ends & has a wide central section. The muscle consists of 3 parts which are joined to the vertebral column through tendinous slips:
- Superior oblique part – begins from the anterior tubercles of transverse processes of the 3rd, 4th, and 5th cervical vertebrae (C3 to C5).
- Vertical intermediate part – begins from the anterior surfaces of bodies of the lower 3 cervical or the superior 3 thoracic vertebrae (C5 to T3).
- The inferior oblique part – is the tiniest section of the longus Colli muscle. It originates from the anterior surfaces of bodies of the 1st 3 thoracic vertebrae (T1 to T3).
Insertion
- Superior oblique part – The muscle ascends slowly in a superomedial direction to diverge on the anterior tubercle of the anterior arch of the atlas (C1).
- Vertical intermediate part – This muscle section ends into the anterior surface of the bodies of the 2nd, 3rd, or 4th cervical vertebrae (C2 to C4).
- The inferior oblique part – It ascends superolateral, diverging into the anterior tubercles of transverse processes of 5th or 6th cervical vertebrae (C5 to C6).
Nerve Supply
- Longus Colli muscle is nerve supply by the anterior rami of the 2nd to 6th cervical spinal nerves (C2 to C6).
Blood Supply
The blood supply to longus Colli arrives from the muscular branches of the following 3 arteries:
- From the Vertebral artery
- From the Inferior thyroid artery
- From the Ascending pharyngeal artery
Action
- It works as a Bilateral contraction: Neck flexion
- It also works as Unilateral contraction: Neck contralateral rotation, and neck lateral flexion (ipsilateral) same side.
The function of Longus Colli Muscle
- Bilateral contraction of the muscle responsible for flexion of the neck (i.e. forward movement). Unilateral contraction, especially of the inferior oblique part, also causes weak lateral flexion (ipsilaterally or same side) or the contralateral rotation of the neck. However, some sources doubt the unilateral work of longus colli due to its almost mid-sagittal position. These actions have necessary stabilizing functions for the vertebral column, aligning the head or the neck for upright posture.
Clinical Significance of the Longus Colli Muscle
- Calcific tendinitisÂ
- Calcific tendinitis of the longus Colli muscle occurs because of the deposition of the calcium hydroxyapatite crystals in the tendons of the longus Colli muscle. Acute calcific tendinitis of the longus Colli muscle will occur. The Calcific tendinitis presents with acute onset of neck pain, stiffness, dysphagia, or odynophagia, or must be differentiated from the retropharyngeal abscess or any other sinister conditions. Imaging diagnosis is by CT or MRI, illustrating calcification in the muscle in addition to retropharyngeal edema. Symptoms include Neck pain, Pain in swallowing, Abnormal swallow, Decreased neck motion, or Fever. Treatment consists of non-steroidal anti-inflammatory drugs.
- Whiplash-
- Longus Colli is a large skeletal muscle of the neck which is responsible for flexing the neck or the head. The longus colli is part of a group of muscles known as the deeper flexor muscles, which give neck stabilization. Whiplash is the most general cause of injury to the longus Colli. During whiplash, the jerking back of the head might cause trauma to the cervical spine or it can slightly tear and dangerously rip a few muscles in the neck including the longus Colli. Muscle spasms will result from whiplash or it might alter the curvature of the spine. The portion of pain is on the bedside or backside of the neck. Treatments consist of the use of analgesics, anti-depressants, muscle relaxants, or the cervical collars

Suboccipital Muscle Stretch
Manual Stretching
- Patient position & the procedure: Sitting
How to do:
- Marked the spinous process of the 2nd cervical vertebra or afterward stabilize it with the thumb or with the second metacarpophalangeal joint (or with the thumb or the index finger surrounding the transverse processes).
- Tell the patient smoothly nod the head, doing just a tipping action of the head on the upper spine. Illustrate the motion by putting the different hands across the forehead of the patient.
- You can hold for 25 to 30 secs & then do three reps.
- Patient position and procedure: Supine
- How to do:
- Sitting on a stool at the head of the treatment table while the forearms are resting on the table. 1 hand stabilizes the C2 vertebra by grabbing the transverse processes between the proximal part of the thumb or the index finger; the opposite hand assists the occiput.
- Nod the head of the patient with the hand below the occiput to take up the slack of the suboccipital muscles; then tell the patient to roll the eyes upside.
- This creates a gentle isometric contraction of the muscles of the suboccipital. Afterward maintaining for 6 secs, tell the patient to roll the eyes downward.
- As the suboccipital muscles easy, take up the slack by passively nodding the head through a new range of motion. The only movement should be happening between the occiput or the C2.
- The contraction is slow in order to not cause the overflow into the multi-segmental erector spinal muscles or the upper trapezius muscles.
- You can hold for 30 secs them repeat three reps.
Self-Stretching
- How to do:
- Patient position & the procedure: Supine or sitting. Explain to the patient to nod the head, and place the chin nearer to the larynx till a stretch is felt in the suboccipital region. Just gave a minor pressure beneath the occipital area with the palm of the hand while tipping the patient’s head forward will reinforce the motion.
- You can hold it for 30 secs & then repeat three reps of it.
Longus Colli Muscle Stretch
