Torticollis can also be caused by problems with bones, muscles, or the spine in the neck, leading to difficulty moving the head and neck normally. [25] Knowing about the sternocleidomastoid muscle and how it works is crucial for doctors to diagnose and treat torticollis correctly, so they can find and fix the problem causing it.

In this same cantilevered head position, the longus colli muscles and other deep neck flexors around the front of the neck are hardly being used, so they become weak, allowing the chin to poke out. The combined effect of all the above in the cantilevered head position, with the chin poked out, is to compress every facet joint in the cervical spine.
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
The deep cervical fascia (or fascia colli in older texts) lies under cover of the platysma, and invests the muscles of the neck; it also forms sheaths for the carotid vessels, and for the structures situated in front of the vertebral column. Its attachment to the hyoid bone prevents the formation of a dewlap. [1]
Put away the wigs, the hair plugs, and the overpriced growth creams. Science may have a more natural solution to this cranial conundrum—without bidding a not-so-fond farewell to your follicles.
It promotes stabilization of head position by innervating the neck muscles, which helps with head coordination and eye movement. Its function is similar to that of the tectospinal tract. The lateral vestibulospinal tract provides excitatory signals to interneurons, which relay the signal to the motor neurons in antigravity muscles. [6]
The sternohyoid muscle is a bilaterally paired, [1] long, [1] thin, [1] [2] narrow strap muscle [2] of the anterior neck. [1] It is one of the infrahyoid muscles. It is innervated by the ansa cervicalis. It acts to depress the hyoid bone. The sternohyoid muscle is a flat muscle located on both sides of the neck, part of the infrahyoid muscle group.
