Central nervous system specific protein

Many people often encounter some inexplicable physical changes in their lives. The most common one is the central nerve-specific protein. This type of protein can be distributed in the nervous system and has a great impact on our body. At the same time, it can play a good dominant role. However, since these important roles are not introduced widely enough, many people only have a one-sided understanding and need to have a correct understanding of this.

Neurocan is a specific protein secreted by neurons and widely distributed in the nervous system. It can bind to specific receptors on the neuronal cell membrane, namely neuronal adhesion molecules and neuronal glial cell adhesion molecules, regulate cell connections, and affect axon growth.

After central nervous system injury, Neurocan expression increases and inhibits axonal growth. Neurocan plays an important role in the formation of the central nervous system and its repair after injury.

introduce

The central nervous system (CNS) is the main part of the nervous system, including the spinal cord located in the vertebral canal and the brain located in the cranial cavity; it is often located in the central axis of the animal body and is composed of obvious cerebral ganglia, nerve cords or the brain and spinal cord and the connecting components between them.

In the central nervous system, a large number of nerve cells gather together to organically form networks or circuits; their main functions are to transmit, store and process information, produce various psychological activities, and dominate and control all behaviors of animals.

composition

Central nervous system of vertebrates: The brain of vertebrates is located in the cranial cavity and the spinal cord is located in the vertebral canal. The central nervous system of vertebrates develops from the neural tube on the dorsal side of the body during the embryonic period. The head end of the neural tube becomes the brain, and the tail end becomes the spinal cord. The neural tube cavity develops into the ventricles in the brain and into the central canal in the spinal cord. The brain initially consists of three brains: the forebrain, midbrain, and rhombencephalon, which later evolve into the telencephalon, diencephalon, midbrain, cerebellum, pons, and medulla oblongata.

Many nerve fibers in the central nervous system of vertebrates are myelinated. When they are gathered together, they appear white to the naked eye and are called white matter. On the contrary, the area where nerve cell bodies are concentrated appears gray to the naked eye. It is composed of a large number of nerve cell bodies and a large number of synapses on the dendrites and is called gray matter. In the central nervous system, gray matter masses with clear boundaries, which are composed of clusters of nerve cell bodies with the same function, are called nerve nuclei.

The neural activities in the spinal cord are mainly reflex activities carried out on a segmental basis; however, many activities of vertebrates are holistic, which depends on the connection between the brain and the spinal cord. There are many longitudinally running nerve fiber bundles in the central nervous system. There are also many connecting fibers between the left and right sides of the brain and spinal cord. The thickest of these is the corpus callosum between the two hemispheres of the cerebral hemispheres.
