The course of the facial nerve is very complex.

Anatomy of nerves. The nervous system has two major parts. The central nervous system cns and the peripheral nervous system pns. Nerve structure anatomy nerves are the organs that make up the peripheral nervous system pns.

There are many branches which transmit a combination of sensory motor and parasympathetic fibres. They serve as information pipelines that allow the brain and spinal cord to communicate with other tissues and organs. A nerve provides a structured pathway that supports the electrochemical nerve impulses transmitted along each of the axons.

Motor nerves lead to the muscles and stimulate movement. Each spinal nerve contains a mixture. Spinal nerves innervate distribute tostimulate much of the body.

Inside the nerves groups of neurons nerve cells are organized into bundles called fascicles fasciculi. The sensory or afferent division consists of nerves composed of nerve fibers that convey impulses to the central nervous system from sensory receptors located in various parts of the body. An illustration of the main nerves of the arm.

Before diving into the anatomy of the spinal nerves lets list most common terms used in. These nerves are made up of nerve fibers called sensory fibers mechanoreceptor fibers sense body movement and pressure against the body and nociceptor fibers sense tissue injury. The facial nerve is associated with the derivatives of the second pharyngeal arch.

The central system is the primary command center for the body and is comprised of. Cranial nerves innervate parts of the head and connect directly to the brain. Nerves can be categorized into two groups based on where they connect to the central nervous system.

A reflex is an involuntary response that occurs at a subconscious. Anterior ventral and posterior dorsal roots.
