Label all the parts of the brain of the central nervous system.

Explanation:

The brain is a very important central nervous system organ for the functioning of the body. This organ constitutes the major part of the brain, representing about 80% of the total mass of this structure.

The corpus callosum is a structure formed by the union of several myelin fibers, which will cross in the sagittal plane of the brain and penetrate the medullary white center of the brain, thus joining the two cerebral hemispheres. The corpus callosum is estimated to be formed by about 200 to 250 million axon projections.

The fourth ventricle (4rd ventricle) is a cavity located posterior to the bridge, the upper half of the bulb, and anterior to the cerebellum. The cerebellum, in turn, is a mass of nerve matter that forms the back of the brain of man and other vertebrates, located anteriorly and above the medulla; divided into two hemispheres, it is especially responsible for muscle coordination and maintaining balance.

Elongated spinal cord is located in the cranial cavity just above the spinal cord and is one of the most important elements of the central nervous system. It is more or less the shape of a cone trunk, with its base facing upwards. Its length is about three inches. Lying on the occipital basilar drip, it forms an obtuse angle with the medulla.

The spinal cord is the elongated portion of the central nervous system that begins just below the bulb in the foramen magnum, crossing the vertebral canal, extending to the first or second lumbar vertebra, reaching 44 to 46 cm in length. The spinal cord occupies the entire length of the spinal canal in the adult individual. From the end of the spinal cord comes a terminal filament, which runs to the coccyx.
