The Nervous System
The Nervous System is divided into Two Main Divisions: Central Nervous System (CNS) and the Peripheral Nervous System (PNS) Divisions of the Nervous System
The nervous system is comprised of two major parts, or subdivisions, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord. The brain is the body's "control center". The CNS has various centers located within it that carry out the sensory, motor and integration of data.

Overview of the nervous system: Structure and function - Kenhub
2023年11月3日 · The nervous system (NS) is structurally broken down into two divisions; Central nervous system (CNS) - consists of the brain and spinal cord; Peripheral nervous system (PNS) - gathers all neural tissue outside the CNS; Functionally, the nervous system can be categorized into three main areas: sensation, integration and response.
Keep reading to learn more about the divisions of the nervous system, the structures of the nervous system and how messages are transmitted through the nervous system. The nervous system consists of several divisions carrying out various functions. Use the interactive diagram below to learn more about the divisions.
There are 43 pairs of nerves that connect the central nervous system to the rest of the body, and they make up the peripheral nervous system or PNS. The PNS is made up of sensory neurons that are capable of receiving stimuli, and motor neurons that are capable of responding to stimuli.
Autonomic nervous system (ANS) Visceral motor system Sympathetic (thoracolumbar) division Parasympathetic (craniosacral) division Organization 1. st. preganglionic neurons (inside CNS) Sympathetic: intermediate column of spinal cord Parasympathetic: brainstem 2. nd. postganglionic neurons (outside CNS) i.e. autonomic ganglion
This chapter presents some basic information about the major structures of the nervous system and their in-terconnections, an area of study called neuroanatomy. It also includes a general discussion of the relationship between structure and function, an area of investigation known as functional neuroanatomy.
Glia - support cells of the nervous system. Hemisphere - one half of the brain. Ion - charged particle. Jet lag - symptoms that occur after traveling through many time zones. Knee jerk reflex - kicking response seen after a tap just below the knee. Limbic system - interconnected areas of the brain important for emotions.
Neurons and parts of neu-rons, within the brain and spinal cord constitute the central nervous system (CNS) and outside the brain and spinal cord constitute the peripheral nervous system (PNS). Functionally, neurons provide communication by means of electrical impulses conducted from one neuron to another to and from the tissues.
