It supplies nerve fibers to the pharynx, larynx, trachea, lungs, heart, esophagus and most of the intestinal tract and brings sensory information back from the ear, tongue, pharynx and larynx.
The 12 cranial nerves control some of the most important functions of the body. In addition, these nerves allow us to feel pain, indicating when there is a serious problem that requires medical intervention. The cranial nerves appear in pairs at the bottom surface of the brain. Their functions vary, but main functions include muscle control, helping the brain interpret the five senses, and controlling glands in the human body. Each cranial nerve pair controls specific functions of Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), in contrast to spinal nerves (which emerge from segments of the spinal cord). Cranial nerves exchange information between the brain and parts of the body, primarily to and from regions of the head and neck. Spinal nerves emerge sequentially from the spinal cord with the spinal nerve closest to the head (C1) emerging in the space above the first cervical vertebra. The cranial nerves emerge from the central nervous system above this level. Each cranial nerve is paired and is present on both sides. Depending on definition in humans there are twelve or thirteen cranial nerves pairs, which are assigned Roman numerals I–XII, sometimes also including cranial nerve zero Functions. Each of the 12 cranial nerves has a specific function that helps the brain control the actions of the body. 1  The olfactory nerve is involved in the sense of smell. 2  This nerve has access to the cerebral cortex, but does not pass through the thalamus like other cranial nerves. The cranial nerves appear in pairs at the bottom surface of the brain. Their functions vary, but main functions include muscle control, helping the brain interpret the five senses, and controlling glands in the human body. Each cranial nerve pair controls specific functions of There are s omatic and visceral components to the sensory function of the vagus nerve. Somatic refers to sensation from the skin and muscles. This is provided by the auricular nerve, which innervates the skin of the posterior part of the external auditory canal and external ear. The vagus nerve is the 10 th cranial nerve (CN X). It is a functionally diverse nerve, offering many different modalities of innervation. The vagus nerve is one of 12 cranial nerves. It is the longest of the cranial nerves, extending from the brainstem to the abdomen by way of multiple organs including the heart, esophagus, and lungs. The vagus nerve is involved in one of the most common causes of fainting, called vasovagal syncope. This is an overreaction of the body to certain stimuli, like the sight of blood, which involves the stimulation of the vagus nerve. This stimulation causes a drop in blood pressure and heart rate. Cranial nerve X: The tenth cranial nerve, and one of the most important, is the vagus nerve. All twelve of the cranial nerves, the vagus nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column. And the vagus nerve brings sensory information back from the ear, tongue, pharynx and larynx. The term vagus (Latin for wandering) is apt because the vagus nerve wanders all the way down from the brainstem to the colon, a long wandering trek. Complete interruption of the vagus nerve causes a characteristic syndrome. The back part of the palate (the soft palate) droops on that side The vagus nerve is a remarkable nerve that relates to the function of numerous structures in the body. The vagus nerve supplies nerve fibers to the pharynx (throat), larynx (voice box), trachea (windpipe), lungs, heart, esophagus and most of the intestinal tract (as far as the transverse portion of the colon). And the vagus nerve brings sensory information back from the ear, tongue, pharynx and larynx. The term vagus (Latin for wandering) is apt because the vagus nerve wanders all the way down from the brainstem to the colon, a long wandering trek. Complete interruption of the vagus nerve causes a characteristic syndrome. The back part of the palate (the soft palate) droops on that side 4. Trochlear. This motor nerve also supplies to the midbrain and performs the function of handling the eye muscles and turning the eye. 5. Trigeminal. This is a type of largest cranial nerve in all and performs many sensory functions related to nose, eyes, tongue and teeth. There are total 12 pairs of cranial nerves that originate from our brain and brain stem. Each of them carries different functions related to different senses of body. Apart from sensory functions there are also some that work as motor nerves or mixed nerves. Here is a brief description of 12 cranial nerves.
