How do you describe the central nervous system?
What is the central nervous system? The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.

The central nervous system (CNS) consists of the brain and the spinal cord. Our brains have two primary functions, which are to control behavior and to regulate the body’s physiological processes.
What is the central nervous system made of?
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.
What are two interesting facts about the central nervous system?

How is CNS divided?
The central nervous system is divided into two parts: the brain and the spinal cord.
What affects central nervous system?
Blood supply problems (vascular disorders). Injuries (trauma), especially injuries to the head and spinal cord. Problems that are present at birth (congenital). Mental health problems, such as anxiety disorders, depression, or psychosis.

The central nervous system is composed of the brain, spinal cord, and neurons. Sciepro/Science Photo Library/Getty Images The central nervous system (CNS) is comprised of the brain and spinal cord. The CNS receives sensory information from the nervous system and controls the body’s responses.
What is the function of the central nervous system?
The CNS receives sensory information from the nervous system and controls the body’s responses. The CNS is differentiated from the peripheral nervous system, which involves all of the nerves outside of the brain and spinal cord that carry messages to the CNS.
How does the CNS communicate with the rest of the body?
The CNS communicates with the rest of the body through the nerves, which are bundles of fibers which transmit signals to and from the CNS. The nerves which are attached to the spinal cord make up the peripheral nervous system (PNS).
What structures protect the central nervous system?
Since the CNS is so important, it is protected by a number of structures. First, the entire CNS is enclosed in bone. The brain is protected by the skull, while the spinal cord is protected by the vertebra of the spinal column. The brain and spinal cord are both covered with a protective tissue known as meninges.
