What is the role of spinal cord in the central nervous system?
Spinal cord is an integral part of the body communication system. The middle nervous system, which consists mainly of brain, spinal cord and massive system of sensory receptors, is responsible for the processing of internal and external communication. Regarding the specific function of the spinal cord in the central nervous system, this is a direct connection between the brain and other body systems. The information flows from the nerves all over the body and travels along the spinal cord to the brain. Once the information is received, the brain processes it and sends messages along the spinal cord to start the appropriate system reactions. Inside the spine, the spinal cord consists of a bundle of separate nerves, wrapped together as a cable. Measurement of about 16 inches (40.64 cm) long and less than 1 inch (approximately 2 cm) wide, the spinal cord connects to the brain and extends the entire length of the spine. It is protected by membranes filled with liquid known as meninges, which are further protected by the backbone points that surround the spinal column.
In several points, the spinal cord branches into nerve pairs that communicate information and four separate areas of the body: uterine, thoracic, lumbar and sacral areas. These innervated areas facilitate communication from different parts and body systems along the spinal cord, to the brain and then back. For example, the cervical area transmits information to AZ head, neck, arms and hands. Compared to the thoracic region, information transfers information to the AZ heart, chest and other systems in the abdominal area of the body. Without the use of the spinal cord in the central nervous system, the brain would not have a way to obtain information from these remote areas of the body.
illness or damage to the spinal cord cuts the communication between the areas of the brain and the body, similar to cutting the telephone line disconnects the call. For example, when an injury occurs, the role of the spinal cord in the central nervous system is at risk. Severe spinal cord injuries such as in the paraplegic, can cause such disturbance in the central nervous system that the brain alreadyHe is unable to control different muscles and tendons. While body systems and brain can continue to broadcast the right signals and messages, the main communication line is damaged so that the messages cannot go through.
