The Relationship Between The Nervous System and The Endocrine System The cells and tissues in the body are delicate and easily disrupted. They will only be able to function well if all aspects of their chemical and physical environment is continuously adjusted to keep them stable and in equilibrium. The process in which several body systems work together to maintain the balanced environment is called homeostasis. The endocrine and nervous system work closely together to help maintain homeostasis

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

Central Nervous System Stimulants Types Stimulants can range from mild legal forms like caffeine to severe illegal drugs like methamphetamines. Each type has different effects at different levels and all can be lethal if taken in excessive quantities. The first type is the cocaine family which consists of cocaine HCL‚ cocaine freebase or crack‚ and cocaine paste.

to the nervous system. The nervous system controls the bodies involuntary and voluntary movements. The brain and the central nervous system are closely connected and one could not function without the other. Electrical impulses travel through our body through nerve pathways to and from the brain. These electrical impulses are signals that tell out body how to function. When the nervous system is functioning correctly our body easily maintains homeostasis. There are however‚ many diseases and disorders
