The Nervous System The nervous system is the most complex part of the body‚ as they govern our thoughts‚ feelings‚ and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease‚ stroke‚ accidents‚ etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous

The Endocrine System FOCUS: The endocrine system is one of the major regulatory systems in the body‚ along with the nervous system. However‚ the endocrine system responds more slowly‚ and has a longer-lasting‚ more general effect on the body than the nervous system. Endocrine tissues internally produce hormones which are released into the blood‚ where they are carried to target tissue and produce a response. Some hormones bind to receptors on the surface of the cell membrane‚ producing permeability
