Stem Made

what parts are made ​​of the brainstem?

The brainstem is the lower part of the brain, adjacent and structurally continuous with the spinal cord. The upper segment of the human brainstem, the pons, contains nerve fibers that connect the two halves of the cerebellum. It is vital in coordinating movements involving right and left sides of the body. Below the bridge and continuous with the spinal cord is the medulla, which transmits ascending and descending nerve fibers between the spinal cord and brain. Marrow directly controls many activities involuntary muscle and glands, including breathing, heart contraction, dilation of the arteries, salivation, vomiting, and probably laughing. The nuclei of some of the nerves that originate in the brain are also located in the brainstem. The nerve fibers of the brainstem not regenerate not easily, resulting in injury can cause permanent loss of function. (See also nervous system) The lower brainstem is the medulla oblongata, roughly comprising the medullary pyramids and olivary bodies or olives. The bridge is a structure above the core. The reticular system enhancer is located between the spinal cord and metencephalon, and is considered the "core". Differentiation of the brain stem of the brain is complex, both anatomically and taxonomically. Some taxonomies describe the brain stem as the medulla and midbrain whereas others include diencephalic regions. The adult human brain stem emerges from parts of three vesicles in the neural tube.
