Neurotransmitters Type, Structure, and Function
We know that neurotransmitters are signaling molecules that travel across the synaptic space to interact with receptors and propagate signals from one neuron to the next. But what are these molecules? What are their structures? How do...

Introduction to the Endocrine System and Negative Feedback Control
In this lecture, I discuss the endocrine system and how endocrine glands control functions in the body through the release of hormones. The pituitary gland is known as the Master Endocrine Gland and plays a major role in controlling the...

Regulating Peripheral Resistance - Part 1
Mean Arterial Pressure is Cardiac Output times Peripheral Resistance. That means if there's a change in Peripheral Resistance, that will result in a change in Mean Arterial Pressure. In this video, Leslie gets into the topic of...
