What are the cores of the brain stem?

In the cells, the core is traditionally considered to be the center of the cell: the meeting center where the information is stored, processed and distributed. The cores of the brain stem serve a similar purpose because they are central networks through which nerve cells and nerves come and perform their functions. Thus, the cores of the brain are responsible for many feelings and functions that people experience every day, but do not need to think about them consciously. Each core can be classified as a sensory or motor.

Brainst is the most primitive part of the brain. It is located between the main brain and spinal cord and consists of midbrain, PON and Medully. Inside these structures, a wide net of nerves lies and each of these nerves begins on one or more cores of the brain stem.

In general, the nerves can serve either sensory or motor function. As such, they either contribute to the five senses of a person or help in movement. Therefore, the brain -cores are referred to as sensory or motor nuclei depending on the nature of the nerves that turn them outthey are lying. If the nerve has sensory and motor skills, it will be connected to the sensory core and motor cores.

While sensory nuclei usually occur on the sides of the brain stem, motor cores are attached in the middle - or medial - part of the brain stem. Most of these cores are associated with only one nerve, but occasionally can develop more nerves from the lonely nucleus.

There are 12 cranial nerves that come from the cores of the brain stem. These nerves perform different individual functions, including eye movement, facial movement and aroma or tasting. For example, the eyepiece nerve is a motor nerve responsible for maintaining some mobile eye muscles. The nucleus for this nerve is known as the oculomotor nucleus. Other That cores contain the corresponding nerves, include the following: Abducense nuclei, trochlear cores, vestibular nuclei and hypoglossal cores.

While most brain cores are named after the nerves they create, there are several exceptions. For example, the Edinger Westphal core is located around the eyepiece core and boasts the nerves responsible for narrowing the pupils. Furthermore, a nerve that carries both sensory and motor capacity related to the face and mouth - trigeminal nerve - has two core origin: the intermediate core and motor core. Furthermore, the versatile vagus nerve has three cores of the brain stem: Ambiguus core, secretory parasympathetic nucleus and lonely nucleus. In addition, they have some nerves, such as a lone core, a connection with more than one skull, and therefore does not share a name with any particular nerve.
