Nerves of the Superficial Tissues of the Back 3D

  • Accessory Nerve
    • * Also known as the eleventh cranial nerve, the accessory nerve arises from the spinal cord and travels through the foramen magnum.
    • * Passes through the jugular foramen, and joins the vagus nerve to innervate the sternocleidomastoid and trapezius muscles.
    • * Is responsible for movement of the head, neck, and shoulders.                                                                                                                                                                                                                                                                                                                                                                                                                                             
  • Dorsal Scapular Nerve​​​​​​​
    • * Arises from the C5 nerve root and innervates the rhomboid major, rhomboid minor, and levator scapulae muscles.
    • * Runs along the medial border of the scapula and is vulnerable to injury during surgical procedures or trauma to the upper back.
    • * Damage to the dorsal scapular nerve can result in weakness or atrophy of the muscles it innervates.

 

  • Greater Occipital Nerve​​​​​​​
    • * Arises from the C2 nerve root and runs through the muscles at the back of the neck to supply the skin on the back and top of the head.
    • * Passes through the semispinalis capitis muscle and emerges at the base of the skull before branching out to the scalp.
    • * Is often implicated in headaches, particularly migraines, and can be targeted with nerve blocks to provide relief.

 

  • Lesser Occipital Nerve​​​​​​​
    • * Arises from the C2 and C3 nerve roots and runs along the posterior border of the sternocleidomastoid muscle.
    • * Supplies the skin overlying the lateral part of the occipital bone and the mastoid process.
    • * Can be involved in headaches and neuralgia, and can be targeted with nerve blocks for pain relief.

         

  • Least Occipital Nerve​​​​​​​
    • * Arises from the C2 and C3 nerve roots and supplies the skin overlying the occipital bone.
    • * Is a small nerve that branches off the greater occipital nerve and runs laterally to innervate the skin over the occipital bone.
    • * Is involved in sensations such as touch, temperature, and pain in the area of the back of the head.
