What is a hypoglossal nerve?

hypoglossal nerve is one of the two cranial nerves that innervate the tongue and provide tongue muscles signals from the brain that allow it to move. Hypoglossal nerves play a decisive role in eating, swallowing and speaking. Disorders that include one or both hypogloss nerves can cause problems with all these tasks and, in some cases, may expose the patient the risk of complications such as random fluid inhalation due to impaired reflex swallowing. These nerves, also known as the 12th cranial nerves, arise in Medulle and travel through the hypoglossal channel in the skull to reach the language. Along the way, contact with the vagus nerve and are also involved with carotid artery and jugular vein. When the tongue is achieved, the hypoglossal nerves branch into the four main sections that strip around the tongue to innervate the entire surface.

Some hypoglossual nerve activities occur without very conscious thinking, such as swallowing to clean the mouth of saliva. Others have to beto teach. Many languages ​​require specific and sometimes unusual use of language to create the desired sounds and children must learn to manipulate their languages ​​to create these sounds. Similarly, adults who are accustomed to talking one language may have difficulty adapting to the sounds of another because they are used to moving their languages ​​in a very different way.

trauma to the brain stem, such as infection or stroke, may disrupt the function of the hypogloss nerve. Patients may also have problems with these nerves due to the neck trauma, including surgery that nicknames or guarantees the nerve. People with hypoglossal nerve problems classically have tongues that attract to the one hand when they are broadcast, along with the general tongue and difficulty swallowing. Wasting tongue can also occur.

surgery around the head and neck must be performed with special care to avoid againThe only skull nerves that innervate the face. Nerve damage can lead to problems that differ from partial paralysis that can cause social problems with serious damage, resulting in complications for the patient. Surgeons who normally work in this area can regularly decide to work with corpses so that they can safely disassemble their heads and neck to overcome the nerves in the area and to take into account variations and abnormalities that could occur in surgery.
