Human Physiology – Regulation of Digestion: Saliva Synthesis and Secretion

>>Dr. Ketchum: We’re going to be looking at gastrointestinal secretion and its regulation. So specifically at this point in time, we’re going to be focusing on saliva secretion followed by acid and pepsinogen secretion in the stomach. The following video will discuss secretion of pancreatic juice and bile, and then rates of fluid movement. All […]

Human Physiology – Single- and Multi-Unit Smooth Muscle

>>Dr. Ketchum: This video will compare and contrast the two types of smooth muscle: single-unit, also known as visceral smooth muscle, and multi-unit. Multi-unit is in the first column. Single-unit is in the second column. Single-unit, again, is also called visceral smooth muscle. So be sure you know single-unit as visceral smooth and use those […]

Human Physiology – Ionic Basis of Action Potential, Part I

>>Dr. Ketchum: In this segment of the neural integration lecture series, you will learn about the ionic basis of an action potential. And so the goal is to view how a neuron generates an electrical signal, and how that signal can be propagated down the neuron. So like I mentioned earlier, we’ve already discussed that […]

Human Physiology – Hormonal Secretion During the Mid-Follicular Phase

>>Dr. Ketchum: So let’s get into some more detail here. So what we’re going to do first is focus on the mid-follicular phase. So for the mid-follicular phase, keep in mind that we’re talking about the ovarian cycle and that this mid-follicular phase is going to begin with a primary follicle. And remember, a primary […]
