Neuralgia, or nerve pain, can be caused by number of different factors. Pressure on a nerve, infection, and nerve trauma are just a few of the things that can cause pain to travel along the length of a nerve path. Every organ and muscle in the...
Problems with the nerves that control the face can not only cause pain but numbness and weakness as well. This can make eating and speaking difficult. It is always best to have the cause of nerve pain in the face properly diagnosed, as in some...
Located beneath the large muscles on either side of the neck, or the sternocleidomastoids, the carotid sheath, part of the cervical band of tissue, or fascia, encloses the carotid artery, the internal jugular vein and the vagus nerve. World...
The cranial nerves are 12 pairs of nerves that connect directly to the brain, unlike most other nerves which connect to the spinal cord. The nerves going out to the body may be voluntary, such as those controlling skeletal muscles, or they may be...
There are twelve nerves in the human body that exit from the central nervous system via openings in the skull. These are known as cranial nerves. The 12 cranial nerves are responsible for regulating numerous diverse functions, from allowing the...
Cranial nerves are a set of 12 nerve pairs that connect from the brain to areas of the face, neck, shoulders and some internal organs. The nerves run through holes in the skull. Each set of nerves are paired for service on each side of the body....
The brain stem links the spinal cord to the brain. Messages between the brain and the rest of the body pass through the brain stem in large nerve bundles. However, the brain stem is more than a nerve impulse highway. According to Dr. Richard...
The head is complex, but functional. Like the rest of the body, the head consists of skin, bone, blood vessels and nerves. However, the head also contains most sensory organs, such as the nose, eyes, ears and mouth. These structures, along with...
Of the 12 cranial nerves that exit from the brain through openings in the skull, five serve functions having to do with the mouth. Some of these are sensory nerves, which allow the brain to detect sensation in and around the mouth. Some are motor...
Ear pain, which may be in one ear or both, can feel sharp, dull or burning. Ear pain may be caused by a condition of the ear, such as an infection, or it may be due to deferred pain secondary to a condition affecting another part of the body....
There are two ways that nerves exit the central nervous system and become part of the peripheral nervous system--through openings in the vertebrae of the spine or through openings in the skull, or cranium. Twelve cranial nerves conduct signals to...
There are 12 cranial nerves that pass directly from the brain through openings in the skull. Each of these nerves serves a unique function: some provide sensory information to the brain; some allow messages to pass from the brain to muscles,...
Researchers have observed low brain levels of serotonin and hypersensitivity to dopamine in subjects with primary headaches, headaches that do not result from another medical condition. Drugs that raise the brain’s levels of serotonin and...
The human digestive tract, while living, measures approximately 20 feet long. Your mouth is the entrance, and your anus is the main exit. When you swallow foods or beverages, you also swallow air, which contains oxygen and nitrogen. Carbonated...
There are 12 paired cranial nerves that exit the skull under the brain's surface that extend to various parts of the head, neck, chest and abdomen. The cranial nerves comprises three nerve types: motor nerves that send an impulse signal to a...
