The brainstem consists of the medulla oblongata, the pons, and the midbrain from bottom to top. It is located in the anterior part of the posterior cranial fossa, connected to the mesencephalon and the spinal cord, with the medulla oblongata and the ventral side of the pons adjacent to the slope of the occipital bone in the anterior part of the posterior cranial fossa, and the dorsal side connected to the cerebellum. The brainstem is an important part of the central nervous system, and its main function is to maintain the physiological functions of the body’s life, such as heartbeat, respiration, digestion, body temperature, sleep and so on. The brainstem is an important life center of the human body. Damage to the brainstem may cause symptoms such as impaired consciousness, ankylosis, or even paralysis and death. It is recommended that patients with brainstem damage should consult a doctor in time and be treated under the guidance of a professional doctor, and should not be treated blindly to avoid adverse consequences.
