SPINAL NERVES

1. DORSAL RAMI

The dorsal rami of the Spinal Nerves contain both sensory and motor fibers, with the exception of the first cervical nerve. They course toward the Skin and Muscles of the back and the occipital region. Notable among them are the dorsal ramus of the first cervical nerve, known as the suboccipital nerve (which innervates the short suboccipital muscles), and the dorsal ramus of the second cervical nerve, knownas the greater occipital nerve (which innervates the Deep Muscles of the back and the skin of the occiput). The sensory fibers of the lumbar and sacral dorsal rami innervate the skin of the upper and middle gluteal regions and are referred to as the superior and middle clunial nerves. Other dorsal rami of the spinal nerves do not have specialized names.
