The nervous system is a complex organ system that is responsible for the control of the body through a specialized network of cells. These cells called neurons are the main channels of nerve impulse transmission from the central nervous system to the peripheral areas in the body. These neurons also send signals from the different areas in the body back to the brain for interpretation and action. For instance, when the hand touches a hot object, the nerves in the hands transmit signals to the spinal cord and into the brain. The brain then interprets it as hot and injuring, thereby nerve impulses are sent to the muscles in order for the person to remove the hand from the hot object. Although the steps seem complicated, these occur in about a short time less than a second.
The nervous system consists of two areas: the central nervous system and the peripheral nervous system. The central nervous system consists of the brain and the spinal cord while the peripheral nervous system consists of all other neurons that are connected from the central nervous system into the peripheral areas of the body.
The central nervous system is considered the main regulatory center of the body. The central nervous system consists of various parts that play a specific role in the regulation of the body processes. The brain is the main organ in the central nervous system that controls and regulates all body functions. The spinal cord on the other hand, serves as the main pathway for nerve impulses from the peripheral areas in the body into the brain. Damage or problems in the spinal cord lead to problems in the transmission of nerve impulses such as pain, sensations and movements.
The peripheral nervous system consists of sensory and motor neurons, ganglia and the nerves that connect them to the central nervous system. Peripheral nervous system consists of the autonomic nervous system that innervates the internal organs in the body outside the brain and the spine. In addition, the autonomic nervous system is composed of the sympathetic and the parasympathetic system. Sympathetic nervous system regulates most of the internal organs except the digestive system and the reproductive system, which are regulated by the parasympathetic nervous system.
There are two kinds of cells in the nervous system: the neurons and the glial cells. The basic unit of the nervous system is the neurons. The neurons have different parts such as the axons and dendrites, which produces nerve signals and transmit them to other neurons through a synapse until they reach the central nervous system. On the other hand, glial cells are non-neuronal cells that provide support and nutrition to the neurons. They may form the myelin sheath that protects the neurons and makes it easier to transmit nerve impulses in between nerve cells. When the nerves cells or neurons are damaged or died, they tend not to regenerate. This makes disease in the nervous system as degenerative and irreversible, meaning that the conditions eventually progress when damage to the neurons are not prevented. However, the glial cells tend to regenerate.
The nervous system is a very important organ system. Chiropractic care focuses on the treatment of conditions through the principle of nerve impulse transmission. Dr. Mohr is a chiropractor in Tampa, FL that has extensive knowledge and experience with the nervous system, as well as all the problems and solutions associated with it. Problems can be corrected through improving the spine, hence correcting abnormal nerve impulse transmissions.
