Introduction Nervous systems are composed of circuits of neurons‚ highly specialized cells that communicate with each other and with other types of cells by electrical or chemical signals.—The central nervous system (CNS) is composed of brain and a nerve cord. The peripheral nervous system (PNS) consists of all neurons and their projections that are outside and connect with the CNS. The most basic circuits is a reflex arc‚ which occurs rapidly in response to inputs from the sensory neurons and

cavities. Body membranes are made up of epithelial and connective tissue layer. Mucous membrane cover openings that are exposed to the outside world. For example‚ mucous membrane is present in the nose‚ respiratory tract‚ male and female reproductive systems‚ stomach and intestines. Epithelium of mucous membrane is attached to lamina propria‚ a loose connective tissue layer that stabilizes the epithelium in place. Goblet cells in the epithelium make mucus which is a liquid that protects the mucous membrane

The nervous system is the most important system in the body. It transmits impulses to and from the brain. Disruption of the nerve cells and fibers that transmit the messages severely impairs the body’s ability to carry out complex function. Once a disruption occurs‚ one may never recover and neurological function will steadily degrade. Multiple Sclerosis is a disease that disrupts this network. Multiple Sclerosis (MS) is the most common disabling neurological disease in young adults between 20 and

Nervous System: an extensive network of specialized cells that carries information to and from all parts of the body. Neuron: the basic cell that makes up the nervous system and that receives and sends messages within that system. Dendrites: branchlike structures that receive messages from other neurons. Soma: the cell body of the neuron responsible for maintaining the life of the cell. Axon: tubelike structure that carries the neural message. Glial cells grey fatty cells that provide support for
