The cerebral cortex is what we see when we look at the brain. It is the outermost portion that can be divided into the four lobes of the brain. Each bump on the surface of the brain is known as a gyrus, while each groove is known as a sulcus.
The brain is made up of billions of neurons and that it also has a number of specialized parts that are each involved in important functions. While there is still a great deal that researchers do not yet know about the brain, they have learned a great deal about the anatomy and function of the brain.

Autonomic nervous system (ANS) is a functional division of the nervous system, with its structural parts in both the central nervous system (CNS) and the peripheral nervous system (PNS). It controls the glands and smooth muscle of all the internal organs (viscera) unconsciously.
The hypothalamus, just above the brain stem, acts as an integrator for autonomic functions, receiving ANS regulatory input from the limbic system to do so. The autonomic nervous system has three branches: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.
The autonomic nervous system is unique in that it requires a sequential two-neuron efferent pathway; the preganglionic neuron must first synapse onto a postganglionic neuron before innervating the target organ.

The peripheral nervous system (PNS)is the division of the nervous systemcontaining all the nerves that lie outside of the central nervous system (CNS). The primary role of the PNS is to connect the CNS to the limbs, and skin.
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. These two components cooperate at all times to ensure our lively functions: we are nothing without our nervous system!
The primary role of the PNS is to connect the CNS to the limbs, and skin. These nerves extend from the central nervous system to the outermost areas of the body. The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment.

Last Updated: Jun 15, 2018. The nervous system consists of the brain, spinal cord, sensory and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
Functions of the Nervous System. The nervous system has 3 main functions: sensory, integration, and motor. Sensory. The sensory function of the nervous system involves collecting information from sensory receptors that monitor the body’s internal and external conditions.
