The system responsible for governing the organized function of our devices is the nervous system (SN), which captures external stimuli through receptors, processes them and translates them into electrical impulses that leads to the central nervous system (CNS), through a system of conductors (nerves), and thus, the CNS elaborates a response sent by the nerves and carried out by other systems or tissues in response to the stimulus.
The nervous system of vertebrate animals, including mammals and humans, can be divided into two distinct parts, the central nervous system, consisting of the brain and spinal cord and the peripheral nervous system, which is formed by the sensory nerves and engines that link the central nervous system with the rest of the organism.
The central nervous system is one of the portions in which the nervous system is divided.
The trigeminal nerve is a cranial nerve of the central nervous system that has three main branches: the ophthalmic nerve, the maxillary nerve and the mandibular nerve. One, two or all three branches of the nerve can be affected. It is responsible for sensory data such as touch (pressure), thermoception (temperature) and nociception (pain) in the area of the face. It is also responsible for the motor function of the muscles of chewing.
The trigeminal nerve is an essential part of the migraine process. A traditional and solid theory about the cause of migraine is a disorder of the central nervous system (CNS) caused by a sensitization of the trigeminal nerve. In migraine, several stimuli can cause a series of neurological and biochemical events that affect the vascular system of the brain.
