Describe The Structure And Function Of The Nervous System //

The nervous system can be divided into regions that are responsible for sensation sensory functions and for the response motor functions. But there is a third function that needs to be included. But there is a third function that needs to be included. In animals, in addition to chemical regulation via the endocrine system, there is another integrative system called the nervous system. A nervous system can be defined as an organized group of cells, called neurons, specialized for the conduction of an impulse—an excited state—from a sensory receptor through a nerve network to an effector, the site at which the response occurs.

The anatomy of the nervous system in humans consists of the brain and spinal cord, along with the primary sense organs and all the nerves associated with these organs. The brain and the spinal cord form the central nervous system CNS. The central nervous system CNS is the brain and spinal cord, and the peripheral nervous system PNS is everything else [link]. The brain is contained within the cranial cavity of the skull, and the spinal cord is contained within the vertebral cavity of the vertebral column. The parasympathetic nervous system activates tranquil functions, such as stimulating the secretion of saliva or digestive enzymes into the stomach and small intestine. Generally, both sympathetic and parasympathetic systems target the same organs, but often work antagonistically. a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain, primary function is transmission of neural signals between the brain and the rest of the body gray matter major component of the CNS, consisting of dendrites and both unmyelinated axons and myelinated axons, glial cells and capillaries.

The structure and function of the nervous system. The conditions inside our body must be carefully controlled if the body is to function effectively. The conditions are controlled in two ways with. The sensory functions of the nervous system register the presence of a change from homeostasis or a particular event in the environment, known as astimulus. The senses we think of most are the “big five”: taste, smell, touch, sight, and hearing.

The four primary functions of the nervous system are the sensory, communicative, integrative and motor functions. The nervous system allows the body to respond quickly to various stimuli. The purpose of the nervous system is to coordinate all bodily functions. The neuron and nervous system.Anatomy of a neuron. Overview of neuron structure and function.
