What is the relationship between the brain and the central nervous system?
In discussions on anatomy, brain and central nervous system (CNS) can be referred to as separate entities. However, the brain is part of the central nervous system, as well as the spinal cord. It works as a body control center, which also presents information to receive information, which makes electrical signals called nerve pulses. These nerve pulses are sent along the spinal cord and out into the body tissue 檚 檚 the nerves leaving the spinal cord column and add messages from the brain, such as the commands to the muscles to download. On the other hand, the peripheral nervous system, which consists of nerves and nerve cells distributed throughout the body, sends information from the body back to the brain for interpretation.
Where the brain is an information center of the nervous system, the Central Nervous System is responsible for transmission and interpretation as a whole message sent between the brain and the body. Nerve pulses that travel toward the brain or from the brain must bedirected up or down the spinal cord, the lower part of the central nervous system. Those sent from the brain and out to the body are referred to as motor signals, because they generally say body muscles to move in response to the stimulus. An example would be to enter from the sidewalk to the sand: cells called sensory receptors indicate the brain that the Earth is no longer solid under one leg and coordinates the brain and central nervous system and sends the motor signal back to the muscles used to walk.
The central nervous system also receives nerve impulses from the body known as sensory signals. Sensory receptor cells in the skin and throughout the body send updates to the brain about everything, from pain to temperature to organ function - in this way maintain its stable operation, known as homeostasis. These signals travel across the spinal cord to the top of the CNS: brain and brain stem. There can be interpreted and a suitable body response such as an increase in saliva in the ÚSTech in anticipation of food, or quickly get out of the sand that is too hot to go. Thanks to this coordination of the sensory input and response of the central nervous system and peripheral nerves and receptors, the body can adapt to both the internal and external environment.
