Reconstruct the orthogonal views of the facial nerve (cranial nerve VII) at the level of the CPA, meatus of the IAC, and fundus of the IAC as described under step 4.2.3. It is derived from the fact that each nerve, one on each side of the pons, has three major branches:.

Sensory neurons deal with a variety of sensations such as proprioception, and stretching. Once patency is established, ask the patient to close their eyes. The fibers from each ventral ramus travels along different routes so that each limb muscle receives innervation from more than 1 spinal nerve to have a backup plan in case of injury.

The twelve cranial nerves are a group of nerves that start in the brain and provide motor and sensory functions to the head and neck.

It is also known as cranial nerve 1 because it is the shortest of the cranial nerves and one of only two nerves (the other is the optic nerve) that bypass the brain stem and connect directly to. They enervates different organs in head and neck region (with the exception of vagus nerve). However, the vagus nerve has branches to most of the internal organs and is the part of the autonomic nervous system.

The cranial nerves appear in pairs at the bottom surface of the brain. Hoarseness is the most common finding;. The rest of the cranial nerves contain both afferent and efferent fibres and are therefore referred to as the mixed cranial nerves.
