What is brainstem function?

Brainstem is the most important life center of human body, which can regulate cardiovascular movement, blood pressure reflex, respiration and vomiting reflex, etc., and plays an important role in maintaining normal physiological activities of the body. Brainstem structure, upper and diencephalon connection, lower and spinal cord connection, including midbrain, pons and medulla oblongata, is a long strip-shaped structure, the interior mainly has nerve nucleus, upper and lower nerve conduction bundle and reticular structure. Due to the small area of the brainstem, various structures are closely arranged among them, once the brainstem shows damage, the consequences may be very serious, and the symptoms may be very obvious. In addition, the brainstem contains the nucleus tractus gracilis and nucleus cuneiformis, which conduct deep sensations, and the red nucleus and substantia nigra, which are related to the extrapyramidal system. These are mainly responsible for the balance of the human body and the regulation of muscle tension and posture.
