Transverse Cervical Nerve - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The transverse cervical nerve is a sensory nerve of the head and neck region. It is a branch of the cervical plexus. It supplies sensation to the skin of the anterolateral neck.

Learn More Course The transverse cervical nerve originates from the cervical plexus of the neck, containing fibres from spinal nerves C2 and C3. It emerges at the posterior border of the sternocleidomastoid muscle (known as Erb’s point – the nerve point of the neck). From there, it travels anteriorly, winding around the sternocleidomastoid. As it approaches the anterior border of the muscle, it moves superficially and pierces the deep cervical fascia to enter the subcutaneous tissue of the neck. It terminates by dividing into superior and inferior branches which innervate the skin of the anterior neck.

Learn More Sensory Function The transverse cervical nerve gives rise to superior and inferior branches which supply the skin of the anterior neck: Superior branches – supply the skin of the upper anterolateral neck. Inferior branches – supply the skin of the lower anterolateral neck Frequent questions What is the function of the transverse cervical nerve? The transverse cervical nerve is a sensory nerve that provides sensation to the skin of the anterolateral neck. It plays a crucial role in transmitting sensory information from this region to the central nervous system. Where does the transverse cervical nerve originate? The transverse cervical nerve arises from the cervical plexus, specifically from the fibres of spinal nerves C2 and C3. It emerges at Erb's point, located at the posterior border of the sternocleidomastoid muscle. How does the transverse cervical nerve travel through the neck? After originating at Erb's point, the transverse cervical nerve travels anteriorly while winding around the sternocleidomastoid muscle. It then pierces the deep cervical fascia to reach the subcutaneous tissue of the neck. What are the branches of the transverse cervical nerve? The transverse cervical nerve divides into superior and inferior branches. The superior branches innervate the skin of the upper anterolateral neck, while the inferior branches supply the skin of the lower anterolateral neck. What is the clinical significance of the transverse cervical nerve? The transverse cervical nerve is important for sensory innervation of the neck, and damage to it can result in loss of sensation in the anterolateral neck region. Understanding its course and branches is essential for surgical procedures in the neck area. Rate This Article
