Structure and Functions of the Nervous and Endocrine Systems

Structure and Functions of the Nervous and Endocrine Systems

by Geoffrey Meyer, PhD, Kevin Ahern, PhD

This course covers the material of content category 3A of the official MCAT exam content outline.

The central nervous system (CNS) is a marvel as well as a mystery. Although we understand that it harbors all of the executive and autonomic functions needed to regulate the human body, we are still no closer to understanding the origins of consciousness. Nevertheless, the anatomy of the nervous system can be a good place to begin, allowing one to understand how its architecture is arranged and meant to interact.

Although not as inscrutable, the endocrine system is just as complex. Hormones play a critical role in the day-to-day functioning of the human body. For example, insulin and glucagon, secreted by the pancreas, regulate tissular uptake of glucose; thyroid hormones regulate metabolic activity; and parathyroid hormone, vitamin D, and calcitriol are charged with regulating calcium and phosphate. Endocrine glands are themselves regulated by the hypothalamus and pituitary gland via a feedback mechanism called the hypothalamic–pituitary axis. Both systems overlap in more ways than one, interacting with each other constantly and also in a way in which both exemplify the influence of a particular tissue over another.

In this course, the student will be introduced to the structure and function of the nervous and endocrine systems. For optimal comprehension, the student must have a preliminary understanding of molecular and cellular biology, emphasizing signal molecules and cellular receptors. Additionally, the student is encouraged to correlate the lessons of this course with their counterparts in histology, physiology, and embryology.

Great Professor and very good explanation!
By Mirela P. on 14. May 2022 for Nerve Tissue

Very good explanation, to understand from beginning!!! I was really afraid about Histology, but Dr. Meyer's explanation gave me confidence and helped me to build a solid foundation, in order to learn more info later on. Thank you, Dr. Meyer!!! You are one of my favourite lecturer! P.S. Since I've studied integrating in my study plan Lecturio"s lectures by Dr. Meyer, my grades at Histology are significally improved!

Easy to understand and memorize

Professor Kevin make it enjoyable course; It helped not only in remembering many info that I forgot in the class, but also I did learn many new valuable information. The fact that the explanation provided by Dr. Kevin is so easy to understand and memorize, make this course very interesting.
