Acute calcific tendinitis of the longus colli muscle can occur. This presents with acute onset of neck pain, stiffness, dysphagia and odynophagia, and must be distinguished from retropharyngeal abscess and other sinister conditions. Imaging diagnosis is by CT or MRI, demonstrating calcification in the muscle in addition to retropharyngeal oedema.

To change this template's initial visibility, the |state= parameter may be used: {{Muscles of neck | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Muscles of neck | state = expanded}} will show the template expanded, i.e. fully visible.
The cervical fascia is fascia found in the region of the neck. It usually refers to the deep cervical fascia . However, there is also a superficial cervical fascia .
It also flexes the neck. [4] When both sides of the muscle act together, it flexes the neck and extends the head. When one side acts alone, it causes the head to rotate to the opposite side and flexes laterally to the same side (ipsilaterally). It also acts as an accessory muscle of respiration, along with the scalene muscles of the neck.
The spinal accessory nerve crosses laterally in the middle part of the muscle and the dorsal scapular nerve may lie deep to or pass through it. [4] The levator scapulae may lie deep to the sternocleidomastoid at its origin, deep or adjacent to the splenius capitis at its origin and mid-portion, and deep to the trapezius in its lower portion.
