Gray Spinal Cord Commissure

The commissure grisea is an anatomical structure of the spinal cord that connects the lateral sections of the spinal cord on the opposite side. It is made up of gray matter and is located at the back of the spinal cord.

The commissure gray is crescent-shaped and consists of two layers of gray matter: outer and inner. The outer layer consists of nerve cells that transmit information between opposite parts of the spinal cord. The inner layer consists of glial cells, which provide support and nutrition for nerve cells.

Functions of the gray commissure

1. Transfer of information between opposite sides of the spinal cord
2. Regulation of motor coordination
3. Participation in the formation of reflexes
4. Connection with the cerebellum and thalamus

External gray commissure

The external gray commissure is located on the posterior surface of the spinal cord and connects the lateral sections to the opposite side. It plays an important role in transmitting information between the right and left hemispheres of the spinal cord. The commissure gray is also involved in the formation and regulation of motor reflexes, such as the flexion and extension reflexes of muscles.

Internal gray commissure

The internal gray commissure is located on the posterior side of the spinal cord between the external gray commissure and the medulla oblongata. It is involved in the regulation of motor coordination and communication with the cerebellum. The internal commissure gray also plays an important role in the formation of reflex reactions, such as the response to pain and temperature changes.

In general, the commissure gray is an important element of the nervous system, which plays an important role in the coordination of movements, the transmission of information and the formation of reflexes. Its violations can lead to various diseases and pathological conditions, such as paralysis and impaired coordination of movements.

The gray commissure of the brain is a fibrous formation that connects the cerebral hemispheres at the place of their conditional transition to the opposite side of the body. The processes of nerve cells also form a kind of ligament of several threads, which connects with the spinal processes of the overlying areas
