The cat lacks nuchal and supraspinous ligaments, perhaps this contributes to its greater flexibility compared to the dog. There are eight bilateral pairs of cervical spinal nerves. This page was last edited on 10 December , at The dorsal branch gives rise to a dorsal cutaneous nerve and it innervates epaxial mm. Hypaxial muscles include some vertebral muscles, the diaphragm , the abdominal muscles, and all limb muscles. Click an image to see it enlarged, view its caption, and toggle its labels. Trunk muscles can be broadly divided into hypaxial muscles, which lie ventral to the horizontal septum of the vertebrae and epaxial muscles, which lie dorsal to the septum.

The first cervical nerve is small and it does not contribute to cutaneous innervation. In the neck, the mass of epaxial musculature is greatly increased and we will identify individual muscles there.
