The central nervous system (CNS) is the part of the nervous system that contains the brain and spinal cord. It is responsible for controlling the body’s voluntary and involuntary actions, as well as for processing information from the senses.
The brain is the largest and most complex organ in the body. It is responsible for controlling all of the body’s functions, including thought, memory, emotion, movement, and sensation. The brain is divided into two hemispheres, the left and right hemispheres. The left hemisphere controls the right side of the body, and the right hemisphere controls the left side of the body.
The spinal cord is a long, thin tube that runs from the brain down the back. It is made up of nerves that carry messages between the brain and the rest of the body. The spinal cord is responsible for controlling many of the body’s involuntary actions, such as breathing and heart rate.
Nerves are long, thin fibers that connect the brain and spinal cord to the rest of the body. They carry messages back and forth between the CNS and the body’s organs and tissues. Nerves are responsible for controlling all of the body’s voluntary and involuntary actions.
The central nervous system is a complex and vital part of the body. It is responsible for controlling all of the body’s functions, and it is essential for life.
A. Brain: The brain is the largest and most complex organ in the body. It is responsible for controlling all of the body’s functions, including thought, memory, emotion, movement, and sensation. The brain is divided into two hemispheres, the left and right hemispheres. The left hemisphere controls the right side of the body, and the right hemisphere controls the left side of the body.
B. Spinal cord: The spinal cord is a long, thin tube that runs from the brain down the back. It is made up of nerves that carry messages between the brain and the rest of the body. The spinal cord is responsible for controlling many of the body’s involuntary actions, such as breathing and heart rate.
C. Nerves: Nerves are long, thin fibers that connect the brain and spinal cord to the rest of the body. They carry messages back and forth between the CNS and the body’s organs and tissues. Nerves are responsible for controlling all of the body’s voluntary and involuntary actions.
