short essay on nervous system

Nervous systems are of two general types, diffuse and centralized. In the diffuse type of system, found in lower invertebrates, there is no brain, and neurons are distributed throughout the organism in a netlike pattern.In the centralized systems of higher invertebrates and vertebrates, a portion of the nervous system has a dominant role in coordinating information and directing responses.

The nervous system is made up of cells. Various receptors and effectors in different parts connect these cells. The nervous system consists of two parts, including the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is divided into the brain and the spinal cord. The PNS consists of the nerves that link the CNS to ...

The central nervous system (CNS) comprises the brain and spinal cord as primary instruments for human coordination and response to external triggers. The commonly accepted structure of the brain consists of the cerebrum, brainstem, and cerebellum. The largest part of the brain, the cerebrum, consists of left and right hemispheres divided by a ...

Nervous tissue, present in both the CNS and PNS, contains two basic types of cells: neurons and glial cells. A glial cell is one of a variety of cells that provide a framework of tissue that supports the neurons and their activities. The neuron is the more functionally important of the two, in terms of the communicative function of the nervous system.

In the human body, the neural system integrates the activities of organs based on the stimuli, which the neurons detect and transmit. They transmit messages in the form of electrical impulses and convey messages to and from the sense organs. Thus, the nervous coordination involves the participation of the sense organs, nerves, spinal cord, and ...

The nervous system is made of two parts: the central nervous system and the peripheral nervous system. The central nervous system (CNS) includes the nerves in the brain and the spinal cords, contained within the skull and vertebral canal of the spine. All the other nerves in the body are part of the peripheral nervous system (PNS).

Human Nervous System. The ability to balance like an acrobat combines functions throughout the nervous system. The central and peripheral divisions coordinate control of the body using the senses of balance, body position, and touch on the soles of the feet. (credit: Rhett Sutphin) The nervous system is responsible for controlling much of the ...

In this essay, we will discuss the importance of the peripheral nervous system (PNS) in human anatomy and physiology. The PNS consists of all the nerves and ganglia outside the brain and spinal cord. It is responsible for transmitting sensory information from the body's receptors to the central nervous system (CNS) and carrying motor commands ...

Identify parts of the CNS (central nervous system) and the PNS (peripheral nervous system). The CNS is the control center of the body. It includes the brain and the spinal cord. The PNS consists of a network of nerves that branch out from the CNS and connects it to the rest of the body. The PNS is involved in both involuntary and voluntary actions.
