Our organs need to communicate with each other throughout the body to ensure interrelated functions can function and maintain proper homeostasis. Two large communicative systems in our body is the nervous and endocrine system.

This course will discuss the nervous system’s structure and the mechanisms by which nerve cells send electrical signals to communicate. Also, the endocrine system and its chemical hormone messengers will be covered.
