What are the structures and functions of the central nervous system?

What are the structures and functions of 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.

What structures make up the central nervous system and the peripheral nervous system?

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 the structures of the peripheral nervous system?

The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

What is the main difference between the central nervous system CNS and the peripheral nervous system PNS )?

What is the main difference between the central nervous system (CNS) and the peripheral nervous system (PNS)? The CNS involves the brain and spinal cord, and the PNS involves the body nerves.

What are the 3 functions of the central nervous system?

The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.

What are the three structures of the nervous system?

The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 1). The brain is contained within the cranial cavity of the skull, and the spinal cord is contained within the vertebral cavity of the vertebral column.

What is central and peripheral nervous system?

Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord.

What is the main difference of the central nervous system?

Main Difference – Central vs Peripheral Nervous system Central and peripheral nervous systems are the two components of the nervous system in animals. The central nervous system comprises the brain and spinal cord. The peripheral nervous system comprises the somatic nervous system and the autonomic nervous system.

What are the functions of the nervous system?

Your nervous system is your body’s command center. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).

What are the basic functions of the central nervous system?

The central nervous system (CNS) functions as the processing center for the nervous system. It receives information from and sends information to the peripheral nervous system. The brain processes and interprets sensory information sent from the spinal cord.
