Facial nerve fibers

The facial nerve is the seventh cranial nerve, or simply CN VII. It emerges from the pons of the The facial nerve also supplies preganglionic parasympathetic fibers to several head and neck ganglia. The facial and intermediate nerves can be. The facial nerve carries both motor and sensory fibers. Motor axons innervate the muscles of facial expression and the stapedius muscle. The course of the facial nerve is very complex. There are many branches, which transmit a combination of sensory, motor and parasympathetic fibres. Facial nerve paralysis is a common problem that involves the paralysis of any structures innervated by the facial nerve. The pathway of the facial nerve is long and relatively convoluted, so there are a number of causes that may result in facial nerve girlsgotgamevolleyball.comlty: Neurology. The facial nerve is composed of several different components that allow it to carry out its various functions. The divisions of the facial nerve functions are broken down into branchial (arising from the branchial/pharyngeal arches) motor, parasympathetic, and sensory (general and special) fibers. At this point, the newly arisen postsynaptic afferent taste fibers and the presynaptic parasympathetic fibers travel with the facial nerve through the facial canal. Before the facial nerve exits the cranium via the stylomastoid foramen, it gives off the chorda tympani.
