What are the divisions of the nervous system and their functions?

The anatomical divisions are the central and peripheral nervous systems. The CNS is the brain and spinal cord. The PNS is everything else and includes afferent and efferent branches with further subdivisions for somatic, visceral and autonomic function.

What are the 2 major subdivisions of the CNS and the PNS?

Summary. The brain and spinal cord make up the central nervous system. The peripheral nervous system is comprised of the somatic and autonomic nervous systems. The somatic nervous system transmits sensory and motor signals to and from the central nervous system.

What are the 2 main divisions of peripheral nervous system?

The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system. The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities.

What are the 5 main parts of the 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….Nerves

  • Afferent, Efferent, and Mixed Nerves.
  • Cranial Nerves.
  • Spinal Nerves.

What are the main divisions of the PNS?

The peripheral nervous system itself is divided into two parts: the somatic nervous system and the autonomic nervous system. Each of these components plays a critical role in how the peripheral nervous system operates.

What are the 4 main parts of the 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.

What are the four main divisions of the peripheral nervous system?

The peripheral nervous system is subdivided into nerves, the autonomic system, and the somatic system. The autonomic nervous system is further subdivided into the parasympathetic and sympathetic nervous systems. The enteric nervous system is an independent subsystem of the peripheral nervous system.

Peripheral Nervous System Divisions. In the remaining article, we will discuss the peripheral nervous system in terms of its subdivisions. Somatic Nervous System. It is a subdivision of the peripheral nervous system that is mainly responsible for carrying out motor activities of the body. Autonomic Nervous System. Physiology. Pathology. Summary.

What are the 2 parts of the peripheral nervous system?

The peripheral nervous system (PNS) has two components: the somatic nervous system and the autonomic nervous system. The PNS consists of all of the nerves that lie outside the brain and spinal cord.

What are the most common CNS disorders?
