In this video, I show the details of how the bending of the stereocilia on the inner hair cells results in the release of neurotransmitters, which ultimately results in hearing. Enjoy.

In this video, I go into the nitty gritty details of how muscle contraction works at the level of actin and myosin in the Sarcomere. I deal with words like troponin and tropomyosin, sarcoplasmic reticulum and Terminal Cisternae. Fun...

In this episode, I discuss the effect of Adrenaline and Acetylcholine on heart rate. Adrenaline speeds it up and Acetylcholine slows it down. They both have their effect by modifying the conductance for ions such as Sodium, Potassium and...

In this episode, I show how the Action potential is generated in cardiac muscle cells and how this results in Contraction of the Heart. When the action potential happens, calcium ions are released from the Sarcoplasmic reticulum, causing...

In this video, I talk about some of the things the body does to regulate stroke volume. I talk about the skeletal muscle pump and how that increases venous returns and about how the increased venous return results in a stronger...

The circulatory system, like every other system in the body, is very important. And when there are problems with your cardiovascular system, your doctor may prescribe various medications to help. Let's take a look at five kinds of...

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...

In this video, we explore the biochemical events that take place during the action potential of an individual cardiomyocyte.

This nugget explains the general characteristics of alkaline earth metals.

Vitamin D Toxicity (Hypervitaminosis D) | Causes, Pathophysiology, Symptoms, Diagnosis, Treatment



***NOTE: I forgot to mention that in the diagnosis of Hypervitaminosis D, it is important to not only measure calcium (which...

Learn the basics about what stomach acid is as part of the acids and bases topic.

In this video, we discuss the events of the cardiac muscle action potential by viewing the action potential graph/diagram.

This video explores the significance of millet in various cultures and traditions throughout history. The video also showcases the diverse influences and uses of millet throughout history and emphasizes its importance as a versatile...

Learn the basics about Alkaline Earth metals which are a group of chemical elements in the periodic table with very similar properties? What are those properties? Find out more in this video!

The video explains how to use the masses of reactants and products in a chemical reaction to calculate the balancing numbers in a symbol equation. Two examples are provided to illustrate the process, and the concept of limiting reactants...

Muscle Physiology: Troponin, Tropomyosin, and Myosin Cross-Bridge Cycle

In this video, we explore the mechanisms of spasticity and baclofen, the major drug used in the treatment of spasticity. Also be sure to check out my video on the Modified Ashworth Scale!

Researchers have found the plants communicate distress by using their own signaling system.

Silicates are a particularly complex class of minerals that all contain silica tetrahedra. Let's look at a few of the sub classes of silicates and the minerals in those groups to learn more about silicate structure.



The 8...

Learn about the nutrient profile of this tiny grain and the benefits it has for our bodies.<b<br/>r/>

Teff part 2/5

In this video, we will discuss the purpose of graded potentials, EPSPs, and IPSPs; and how the summation of all graded potentials by the soma dictates whether an action potential occurs.

Learn the basics about making hard water turn into soft water. What are the methods and techniques used to make that happen? Find out more in this video!

In this video, we explore the three general stimuli for smooth muscle contraction, their mechanisms, and how they converge on cross-bridge cycling.<br/>
* Emphasis on smooth muscle in blood vessels

Ok, so why didn't the skeleton go to the party? Because he had no body to go with! What about why didn't the skeleton cross the road? Because he didn't have the guts! Sorry. If that doesn't tickle your funny bones at least after watching...
