What is a trigeminal core?
trigeminal core is the basis of a trigeminal nerve in the brain stem. It is a place where all the feelings of the face, such as pain and touch, are first processed in the brain. The spinal trigeminal core receives information about pain and temperature in the face, while the main core is the aim of touch and location information. Other skull nerves that mediate the feeling in any part of the face also send fibers to these cores.
The trigeminal nerve is also called the cranial nerve V. It carries the feeling of nerve fibers in the face to the brain for processing. The trigeminal core is a place where all these different fibers leading from the face converge because it is the origin of the fifth skull nerve. Pain and temperature and touch or pressure are transmitted to the nucleus, but with different ways of the brain. Anatomically, the core is divided into three sections starting at the base of the spinal cord and proceeds to the midbdéště.
one section is the backbone trIgeminal core. Starting at the top of the spinal cord, the neuron groups are arranged according to a part of the face in which they process the feeling. Information about the pain and temperature that comes here is then sent to Thalam and the bark, where the conscious experience of feeling is modulated. Before awareness of changes in pain or face position, the information first achieves the backbone trigeminal core. Feedback also sensory fibers from other skull nerves such as face and glossopharyngeal.
The main trigeminal core carries information from various receptors that mediate the feeling of touch on the face. There is no single feeling of touch, but a nerve ending responding to light pressure, deep pressure and stretching in the skin. The neurons of the main core are found in the ponchy tribes are arranged on the face map. Feelings from the chin, nose, faces and other parts of the face are processed separately than integrated into a more unified feeling higher in the brain.
trigeminal coreIt is very close to the brain trunk that regulates breathing, heart rate and pupillary response. Therefore, face pain gets a quick reflective reaction before one fully realizes pain. Furthermore, because all skull nerves arise from the brain stem, tumors or injuries in this area often interfere with the functions of more than one core. For example, a show of origin of pain in a trigeminal nerve is not always easy.
