What is the Brain Stem?

The brainstem (brainstem) is located below the brain, between the spinal cord and the mesencephalon, is a smaller part of the central nervous system, and is irregularly columnar. The brain stem is composed of the medulla oblongata, pontine, and midbrain from bottom to top. The medulla oblongata is connected to the spinal cord.

The brainstem includes four important structures:

1.

Brain stem

1. Rostral medulla: motor cross or cone cross plane, sensory cross or mound cross plane, olive mid plane.

2, pontine: auditory nodule plane, facial nerve mound plane, trigeminal root plane.

3. Midbrain: inferior colliculus plane, superior colliculus plane.

Brain stem function.

The functions of the brainstem are mainly to maintain individual life, including important physiological functions such as heartbeat, breathing, digestion, body temperature, and sleep, all related to the functions of the brainstem.
