What Innervates the longus colli?

The longus colli muscle is a prevertebral muscle of the neck that is innervated by the anterior rami of C2-C6 from the cervical plexus. Longus colli is a weak flexor the cervical spine and when contracting unilaterally it tilts and rotates the cervical spine to the ipsilateral side.

What nerve Innervates the longus capitis?

The longus capitis muscle is innervated by anterior rami of the spinal nerves C1-C3 and occasionally C4, that are the branches of the cervical plexus.

What causes calcific longus colli tendinitis?

Acute calcific tendinitis of the longus colli muscle—also known as retropharyngeal calcific tendinitis—is a rare and benign condition caused by basic calcium phosphate deposition in the tendons of the longus colli muscle that is accompanied by an aseptic inflammatory process.

Which nerves innervate the deep cervical flexor muscles?

All of these muscles are innervated by the suboccipital nerve C1 (Cleland., 2005).

What is the longus colli tendon?

Abstract. The longus colli muscle has three major parts that originate and insert in the upper cervical and thoracic spine. It is a weak flexor of the neck, and when contracted also serves to rotate the neck to the ipsilateral side.

What Innervates rectus capitis anterior?

Innervation. This muscle is innervated by the anterior rami of spinal nerves C1 and C2. The anterior rami of these nerves are connected by a communicating branch, from which the nerves to rectus capitis anterior muscle stem.

What causes neck tendonitis?

Cervical tendonitis is typically caused by repetitive strain/pull on a tendon. This can be due to a specific repetitive motion throughout the day. Another contributing factor may be poor posture, which places undue strain on the muscle and tendon.

What muscles are innervated by C5?

The muscles innervated by C5 are: Serratus Anterior, Deltoid, Ifraspinatus, Teres minor, Teres major, Pectoralis major, Supraspinatus, Biceps, Brachialis, Brachioradialis, Supinator.

What does C7 nerve affect?

The C7 myotome is a group of muscles controlled by the C7 nerve. These muscles include those involved in straightening the elbow, lifting the wrist, elongating the fingers to an outstretched hand, and the triceps muscle in the upper arm.

Which muscles are innervated by C3?

Motor. On the other hand, the motor branches of the cervical plexus form the ansa cervicalis (C1-C3), which is a nerve loop innervating the infrahyoid muscles in the anterior cervical triangle. They also form the phrenic nerve (C3-C5) which supplies the diaphragm and the pericardium of the heart.

Is Longus colli tendinitis a different diagnosis for neck pain?

Longus colli tendinitis (LCT) is not listed among the differential diagnoses for neck pain in many textbooks, which generally only include more common possibilities such as inflammatory, infectious, and rheumatic conditions [ 4 ].

What causes calcific tendinitis of the longus colli muscle?

Calcific tendinitis of the longus colli muscle is caused by deposition of calcium hydroxyapatite crystals in the tendons of the longus colli muscle. Symptoms include:

What is the treatment for longus colli tendinitis?

The neuroradiologist suggested the diagnosis of longus colli tendinitis that was confirmed with contrast-MRI. A soft cervical collar and analgesics were prescribed. Symptoms rapidly improved after three days that the patient could be discharged. The patient reported complete remission of symptoms after seven days.

What nerve innervates the longus colli?

Longus colli muscle is innervated by the anterior rami of the second to sixth cervical spinal nerves (C2-C6). Both bilateral and unilateral contraction of the muscle causes forward flexion of the neck.
