system. there are two major divisions of the nervous system the first is the central nervous system. which is made up of the brain and the spinal cord. the second is the peripheral nervous system which consists of nerves that run throughout the body the peripheral nervous system itself is made up of two subdivisions.

Chapter Review. The nervous system can be separated into divisions on the basis of anatomy and physiology. The anatomical divisions are the central and peripheral nervous systems. The CNS is the brain and spinal cord.

Divisions of the Peripheral Nervous System. The PNS is divided into two major systems, called the autonomic nervous system and the somatic (or sensory-somatic) nervous system. Both systems of the PNS interact with the CNS and include sensory and motor neurons, but they use different circuits of nerves and ganglia.

The nervous system comprises of two group of cells, glial cells and neurons.

In ition to the endocrine system, the autonomic nervous system is instrumental in homeostatic mechanisms in the body. The two divisions of the autonomic nervous system are the sympathetic division and the parasympathetic division.

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).

The nervous system of vertebrates has two main divisions: the central nervous system, consisting of the brain and spinal cord, and the peripheral nervous system, which in humans includes 12 pairs of cranial nerves, 31 pairs of spinal nerves, and the autonomic, or involuntary, nervous system.

In vertebrates it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body.

The two fundamental anatomical divisions of the nervous system are the: Incorrect! The two fundamental anatomical divisions of the nervous system are the Central Nervous System (brain and spinal cord) and the Peripheral Nervous System, which consists of all nerves outside the brain and spinal cord.

The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve (cranial nerve II), along with the retina.

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.

The autonomic nervous system is divided into three parts: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

The peripheral nervous system is itself classified into two systems: the somatic nervous system and the autonomic nervous system. Each system contains afferent and efferent components.

The ANS is divided into three parts: The sympathetic nervous system. The parasympathetic nervous system. The enteric nervous system.

The nervous system is the human organ system that coordinates all of the body's voluntary and involuntary actions by transmitting signals to and from different parts of the body. The nervous system has two major divisions, called the central nervous system (CNS) and the peripheral nervous system (PNS).

The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system.

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 1).
