The brainstem is located in the anterior part of the posterior cranial fossa and consists of the medulla oblongata, the pons, and the midbrain. The internal structure of the brainstem consists of gray matter, white matter, and reticular formation.
The brainstem is located in the anterior part of the posterior cranial fossa and is connected to the mesencephalon from above and the spinal cord from below. The brainstem consists of the medulla oblongata, the pons, and the midbrain from the bottom up.
The medulla oblongata, like an inverted cone, has the function of controlling breathing, heartbeat, digestion, etc. The cerebral bridge is in the center and has the function of coordinating the muscle activities on both sides of the body, etc. The midbrain is located on top of the cerebral bridge, and has the function of controlling the activity of eyeballs and pupils.
The internal structure of the brainstem consists of gray matter, white matter, and reticular formation. The nuclei in the gray matter of the brainstem are divided into three categories: the nucleus accumbens, the nucleus intermedius, and the nucleus reticularis.
The white matter of the brainstem consists mainly of long bundles of upward and downward fibers and fibers that enter and exit the cerebellum. The reticular system is located in the center of the brainstem and is a network of many intricate collections of neurons.
Important physiological functions such as respiration, body temperature and heartbeat are all related to the brainstem, so it is necessary to go to the hospital in time when there are abnormalities and follow the doctor’s instructions for treatment.
