The sternocleidomastoid muscle gets its blood from different arteries in the neck, which bring oxygen and nutrients to keep the muscle healthy. Torticollis can happen when there are issues with the sternocleidomastoid muscle, like if it's too short, causing the head and neck to be in an odd position. [ 25 ]
There are several options of treatment when iatrogenic (i.e., caused by the surgeon) spinal accessory nerve damage is noted during surgery. For example, during a functional neck dissection that injures the spinal accessory nerve, injury prompts the surgeon to cautiously preserve branches of C2, C3, and C4 spinal nerves that provide supplemental innervation to the trapezius muscle.

The triangle formed by the clavicle and the sternal and clavicular heads of the sternocleidomastoid muscle is used as a landmark in identifying the correct location for central venous catheterization. [10] Contraction of the muscle gives rise to a condition called torticollis or wry neck, and this can have a number of causes. Torticollis gives ...
The sternocleidomastoid muscle is tested by asking the patient to turn their head to the left or right against resistance. [ 8 ] One-sided weakness of the trapezius may indicate injury to the nerve on the same side of an injury to the spinal accessory nerve on the same side (Latin: ipsilateral ) of the body being assessed. [ 8 ]
This movement utilizes the bilateral sternocleidomastoid, bilateral scalene complex, bilateral submental complex. Retrocollis is the extension of the neck (head tilts back) and uses the following muscles for movement: bilateral splenius, bilateral upper trapezius, bilateral deep posterior paravertebrals. This is the "chin-in-the-air" version.
The anterior scalene muscle (Latin: scalenus anterior), lies deeply at the side of the neck, behind the sternocleidomastoid muscle.It arises from the anterior tubercles of the transverse processes of the third, fourth, fifth, and sixth cervical vertebrae, and descending, almost vertically, is inserted by a narrow, flat tendon into the scalene tubercle on the inner border of the first rib, and ...
They are located laterally to the transverse processes between prevertebral muscles from the medial side and vertebral (m. scalenus, m. levator scapulae, m. splenius cervicis) from lateral side. There is anastomosis with accessory nerve, hypoglossal nerve and sympathetic trunk. It is located in the neck, deep to the sternocleidomastoid muscle. [5]
Anterior to sternocleidomastoid muscle, posterior to submandibular gland, lateral to carotid sheath. They are medial to the facial nerve at the anterior neck and above the hyoid bone. Skin pit can be found in this location. However, if skin pits are found on both sides of the neck, then, branchio-oto-renal syndrome should be ruled
