Module Outline |
Module 4: The Nervous System and the Endocrine System |
Module 4 begins with a basic introduction to neurons and the human nervous system. The parts of a neuron and how they work are discussed in detail. |
How the nervous system can be sub-divided into a number of parts is explained, emphasizing the role of the sympathetic and parasympathetic nervous systems in the fight or flight response. |
The module concludes by explaining the chemical hormonal system, detailing the various glands and their functions. |
