- The Nervous System. The nervous system is the most complex system of the body, yet it is very conservative in terms of change. The nervous system determines responses of the body to changes in internal and external environments. It also acts as a messenger and coordination system for the body.

The Nervous System Key Takeaways Key Points. The nervous system is the body’s main communication system; it gathers, synthesizes, and uses data from the environment. The most basic unit of the nervous system is the neuron, which serves as both a sensor and communicator of internal and external stimuli.

How does the Nervous System Work? The nervous system is the most complex system in the human body. It is surrounded by a network of more than hundred billion neurons, assisted by many glial cells. Like the processor in a computer, this system works as a data receiving, processing and transferring center for the human body. In short, the nervous system serves as the body's communication system.

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. Together, these organs are responsible for the control of the body and communication among its parts. Sensory. 2  The sensory function of the nervous system involves collecting information from sensory receptors that monitor the body’s internal and external conditions. 3  These signals are then passed on to the central nervous system (CNS) for further processing by afferent neurons (and nerves).

Circulatory System The nervous system is made up of the brain, the spinal cord, and nerves. One of the most important systems in your body, the nervous system is your body's control system. It sends, receives, and processes nerve impulses throughout the body. These nerve impulses tell your muscles and organs what to do and how to respond to the environment.

- The nervous system is a complex, highly specialized network. It organizes, explains, and directs interactions between you and the world around you. The nervous system controls: Sight, hearing, taste, smell, and feeling (sensation). Voluntary and involuntary functions, such as movement, balance, and coordination.

Outline of the human nervous system Outline of the human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body. The human nervous system consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord. The PNS consists mainly of nerves, which are long fibers that connect the CNS to every other part of the body.

Nervous system The nervous system is the part of an animal 's body that coordinates its voluntary and involuntary actions and transmits signals to and from different parts of its body. Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago.In vertebrate species it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains 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.he central nervous system functions to send signals from one cell to others, or from one part of the body to others and to receive feedback. Malfunction of the nervous system can occur as a result of genetic defects, physical damage due to trauma or toxicity, infection or simply of ageing.

Human body Nervous system. As commonly defined, the human body is the physical manifestation of a human being, a collection of chemical elements, mobile electrons, and electromagnetic fields present in extracellular materials and cellular components organized hierarchically into cells, tissues, organs ,and organ systems.he largest organ in the human body is the skin. Covering the entire body, even the eyes, which have a transparent layer of skin called the conjunctiva, the skin offers protection from water, air, sunlight, injury, dirt, chemicals, and microorganisms.
