What are the main function of the nervous system?
The nervous system is a highly integrated system. The nervous system has three overlapping functions based on sensory input, integration, and motor output. At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body.
What are the 5 nervous systems?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
What is the process of the nervous system?
The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
What is the most important part of the nervous system?
The brain and the spinal cord make up the central nervous system. The nervous system is the most complex and highly organized body system. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.
What organs are in nervous system?
The nervous system has two main parts:
- The central nervous system is made up of the brain and spinal cord.
- The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
How is nervous system classified?
The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 8.2).
What is the nervous system simple definition?
The nervous system controls everything you do, including breathing, walking, thinking, and feeling. This system is made up of your brain, spinal cord, and all the nerves of your body. The nerves carry the messages to and from the body, so the brain can interpret them and take action.
What is the primary function of the nervous system?
At the most basic level, the function of the nervous system is to send signals from one cell to others, or from one part of the body to others. At a more integrative level, the primary function of the nervous system is to control the body, by extracting information from the environment and transmitting, processing,…
What do you need to know about the nervous system?
25 things you didn’t know about your nervous system Despite being slower than electrical synapses, chemical synapses greatly increase behavioural flexibility. Electrical impulses produced in neurons can be initiated by neurotransmitters (such as serotonin). Electricity produced in the axons of our neurons is the increase and decrease of sodium and potassium levels in a cell.
What is the relationship of nervous system to body organs?
NERVOUS SYSTEM The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
Do you know all the organs of the nervous system?
