The seventh cranial nerve (CN VII), the facial nerve, is responsible for providing motor innervation to these facial muscles, enabling you to smile or frown. In addition to motor fibers, this multitasking nerve also contains sensory and parasympathetic components.
The facial nerve is the seventh (CN VII) cranial nerve and comprises two roots, a motor root and a smaller mixed sensory, taste and parasympathetic root, known as nervus intermedius, which join together within the temporal bone (TA: nervus facialis or nervus cranialis VII).
The facial nerve, CN VII, is the seventh paired cranial nerve. In this article, we shall look at the anatomical course of the nerve, and the motor, sensory and parasympathetic functions of its terminal branches.
What is the anatomy of the facial nerve? Each of your facial nerves extends from your brain throughout your face like tree roots. The structure (anatomy) of your facial nerves: Starts in your brainstem. Travels through the base of your skull near the vestibulocochlear nerve (eighth cranial nerve).
The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue.
The facial nerve has a complex anatomy. It is one of the longest cranial nerves, extending from the brainstem to the terminal (end) branches, which are located throughout the face. Several structures of the facial nerve—described as nuclei, segments, and branches—produce the four components of facial nerve function.
The facial nerve, also known as cranial nerve VII, is a mixed nerve responsible for both motor and sensory functions. It innervates the muscles of facial expression, the lacrimal and salivary glands, and provides taste sensation to the anterior two-thirds of the tongue.
The facial nerve is also known as the seventh cranial nerve (CN7). This nerve performs two major functions. It conveys some sensory information from the tongue and the interior of the mouth....
Viviana Popa, MD. Contributors. Alexandru Duhaniuc, MD, Sam Gillespie, BSc, Elizabeth Nixon-Shapiro, MSMI, CMI. Humans can make thousands of expressions with their faces, and this is possible thanks to the 7th cranial nerve, also known as the facial nerve.
An overview of the anatomy of the facial nerve (CN VII) including its course, the facial nucleus, branches of the facial nerve and facial nerve palsy.
