This action primarily aims to preserve relative constancy in the body when severe changes occur in the external environment‚ as it very important for the body to maintain homeostasis in order to survive.

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
