The Central Nervous System

Neurodevelopment begins early in the embryogenesis period, but it is finally complete, it takes a long time to complete and complete the most complicated structure in the embryo. The central nervous system begins with a simple neural plate that bends into a groove and then a tube that opens at each end. Within the trunk, the cell creates a nervous system consisting of two major types of cells, neurons and glial cells. These two classes are classified into more types because they are different in function and shape (Hill, 2013).

The central nervous system (CNS) is a part of the nervous system consisting of the brain and the spinal cord. The central nervous system integrates the received information and coordinates and affects the activities of various parts of the symmetrical animal body (all multicellular animals except radially symmetrical animals such as sponges and jellyfish) It is called like this. Most of the nervous system is included. Many people believe that the retina and optic nerve (cranial nerve II), as well as the olfactory nerve (cranial nerve I) and the olfactory epithelium as part of the central nervous system synapse directly to brain tissue without intermediate ganglia. Thus, the olfactory epithelium is the only central nervous tissue that is in direct contact with the environment and is open for therapeutic treatment. The central nervous system is contained in the posterior body cavity, the brain is housed in the cranial cavity, and the spinal cord is located in the spinal canal.

Your nervous system consists of the central nervous system, cranial nerve and peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerve connects the brain to the head. Four pairs of nerves branching from the neck, chest, lumbar region, and ankle of the spinal cord are called peripheral nerves. The peripheral nervous system consists of sensory neurons that operate from stimulatory receptors that stimulate receptors to give information to the central nervous system. It also includes motor neurons that move from the central nervous system to the muscles and glands, which act. The peripheral nervous system is further subdivided into a sensory area and a movement area. Sensory division transmits pulses from the peripheral organs to the central nervous system. Athletes transmit impulses from the central nervous system to peripheral organs, creating effects and actions.
