What do we know about the brain?
The brain is located in the cranial cavity, with uneven surface, and consists of four parts: telencephalon, diencephalon, cerebellum, and brainstem (including midbrain, pons, and medulla oblongata). The morphological structure of the brain is relatively complex, different anatomical parts have different functions, and the occurrence of lesions in different parts will also cause different symptoms and signs. Understanding and mastering these anatomical relationships and the blood circulation of the brain can help determine the lesion location, degree of disease, etiology and pathology. As well as guiding clinical and rehabilitation therapy is of great help. Ronten's life-size human brain anatomy model allows you to better understand the structure of the brain, and at the same time better understand the cause and timely treatment.
The brainstem is the smaller part between the spinal cord and the diencephalon, consisting of the medulla oblongata, pons, and midbrain from bottom to top. The brain is located in the anterior part of the posterior cranial fossa, where the medulla oblongata and pons adjoin the clivus of the anterior part of the posterior cranial fossa on the ventral side and the cerebellum on the back. The space enclosed between the medulla oblongata, pons, and cerebellum is the fourth ventricle, which continues downward from the central canal of the medulla oblongata and spinal cord, and upward to the midbrain aqueduct of the midbrain
The cerebellum is an important motor regulation center. It is located in the posterior cranial fossa. The fourth ventricle is adjacent to the brainstem. The tentorium above is adjacent to the occipital lobe of the cerebral hemisphere.
The diencephalon is formed from the embryonic forebrain vesicles, located between the brainstem and the telencephalon, connecting the cerebral hemispheres and the midbrain. Due to the highly developed cerebral hemispheres, the sides and back of the diencephalon are covered, and only part of the ventral side exposed at the bottom of the brain. There is a narrow cavity in the middle of the diencephalon, the third ventricle, which separates the left and right parts of the diencephalon. Although the volume of the diencephalon is less than 2% of the central nervous system, its structure and function are very complex, and it is the highest central part after the telencephalon. The diencephalon can be divided into 5 parts: the dorsal thalamus, the posterior thalamus, the epithalamus, the subthalamus, and the hypothalamus.
The telencephalon is the highest part of the brain, which evolved from the forebrain vesicles in embryos. During the evolution process, the forebrain vesicles were highly distributed on both sides, forming the telencephalon, the left and right cerebral hemispheres, covering the diencephalon and middle brain. brain and pushes the cerebellum back. The gray matter layer on the surface of the cerebral hemisphere is called the cerebral cortex, and the deep white matter is also called the medulla.
