The brain structure mainly consists of the telencephalon, mesencephalon, cerebellum, midbrain, pons and medulla oblongata. The human brain develops from the differentiation of the anterior portion of the neural tube during embryonic life and is the most advanced part of the central nervous system. It usually consists of six parts, including the telencephalon, mesencephalon, cerebellum, midbrain, pons and medulla oblongata. 1. The medulla oblongata, the pons and the midbrain make up the brainstem, whose internal structure is similar to that of the spinal cord, consisting of gray matter, white matter and reticular formation, and is more complex than that of the spinal cord. It contains a variety of motor and sensory nuclei, such as general somatic motor nuclei and special visceral motor nuclei, which govern the muscle and visceral movements of the human body. 2. The cerebellum is one of the important somatomotor regulatory centers of the body, and its functions are mainly to maintain body balance, regulate muscle tone and coordinate random movements. 3. The mesencephalon is located between the midbrain and the telencephalon, connecting the cerebral hemispheres and the midbrain. 4. The telencephalon consists of the left and right cerebral hemispheres and the inter-hemispheric junction and its inner cavity, including the occipital lobe, parietal lobe, temporal lobe, frontal lobe and other areas, controlling the active functions of the human body, such as hearing, reading and writing. It is recommended that patients with brain damage should consult a doctor in time and under the guidance of a professional doctor to avoid adverse consequences.
