Hindquarters

The hindbrain is an integral part of the brain, to which the cerebellum and the bridge of the brain belong. This formation ontogenetically originates from the fourth cerebral bladder and undergoes a number of complex transformations. The hindbrain is bounded from below by the medulla oblongata, from above - by the legs of the brain, and the lateral divisions merge and form the middle legs of the cerebellum.

The brain stem is the main constituent part of the brain after the hemispheres. In the central part of the bridge is the main accumulation of bodies of neurons - gray matter, as well as the core of the bridge, olive trees and the reticular formation. There are also nuclei of 5-8 pairs of cranial nerves, which participate in the formation of the innervation of the face and other departments. In addition to the cranial nerves, through the trunk pass numerous nerve pillars from the spinal cord, as well as other vital centers of man.

The hindbrain is represented by a white matter in the form of fibers entering the middle legs of the cerebellum. These fibers are intertwined with wide thick longitudinal bundles of pyramidal pathways, which then enter the spinal cord. All fibers have an upward and downward direction, and, depending on the level at which the lesion occurs, specific symptomatology of the disease can be observed. In some places of the brain, the fibers can cross between themselves - this should be taken into account in the diagnosis of abnormalities

The hemisphere of the brain is one of the most mysterious structures of the human body. Hemispheres along with the cortex for a long time were studied by doctors from different countries. Some features of the work of the brain of men and women, children and adolescents were elucidated. However, no one can accurately find out what the mental abilities and inclination of a person to these or those talents depend on.

The hemispheres of the brain consist of gray and white matter. Above, the brain is covered with bark (a cluster of neuron nuclei) which forms folds or furrows. In the process of studying the structure of the furrows it was found out that some of their parts are responsible for vision, some for hearing and sense of smell. Proceeding from this, it can be concluded that there are no idle and unnecessary structures in the brain.

The left hemisphere of the brain is a peculiar center of written and oratorical abilities. Thanks to the left half of the brain, a person is able to perceive information by ear, process and realize it, and also reproduce on paper. Here is also the center of memory, not only long-term, but also short-term.

The right hemisphere is human talent. For a long time it was believed that people are not able to be smart and talented at the same time, but now this myth is dispelled. The right parts of the brain can be called the center of our dreams and fantasies. It is here that the center of the imagination is located.

But in the left divisions, on the contrary, rationality and rough calculation are concentrated. With the help of the left hemisphere, a person realizes what he is doing, oriented in space, able to count and count.

It should not be forgotten that the hindbrain is also the cerebellum, the motor and coordination center of the human body. The cerebellum is also covered with bark - a gray substance with furrows, however it does not perform the same functions as the cortex of the hemispheres. The motor site of the brain consists of hemispheres, a worm and a leg, or the middle part. It is not difficult to see that the cerebellum mimics its structure of the hemisphere of the brain.

The cerebellum is responsible for one of the basic functions of a person - movement. And not just chaotic disorderly movement, but logical, coordinated. This structure of the brain, in combination with the rest, facilitates the finding of the human body in a vertical position and the implementation of targeted movements in a given position.
