In this video, I talk about how the brain processes information on the different pitches that we hear. I'm warning you - it starts off a little scary, but by the end of the video, you will have a good idea of how we hear different...

In this video, I talk about the organ of corti, which is found on top of the basiliar membrane inside the cochlea. When the basilar membrane vibrates up and down, that causes the organ of Corti to move up and down, and the tectorial...

What does it take for an action potential to take place? What are depolarization, repolarization, and hyperpolarization? How are voltage-gated ion channels involved? In this video, you will get answers to all these questions.

How do we hear? How does sound get transferred from the ear all the way to the brain? In this video, I go into all the juicy details. Listen up and have fun.

Photosynthesis is the process that plants use to convert energy from the Sun into food. In this lecture, I talk about the process of photosynthesis, and show the steps involved in producing glucose.



I go into the Light...

The plasma membrane is responsible for maintaining a balance. In this section, I talk about both the structure and the function of the plasma membrane. I deal with the components of the plasma membrane and their functions.

In this video, I go through the details of the 4 types of proteins in the membrane of neurons: The passive/leakage ion channels, Sodium Potassium pump, Voltage-gated ion channels and ligand-gated ion channels

In this Video, I talk about Donnan Equilibrium and how it results in the Driving force.

The second phase of the Action Potential is Repolarization. Voltage-gated Potassium channels open and Potassium leaves the cell making the membrane potential more negative.

Lesson on the Glycerol Phosphate (aka Glycerol-3-Phosphate) Shuttle. NADH produced from glycolysis is unable to enter into the mitochondria because the mitochondrial inner membrane is impermeable and highly selective. Therefore, the...

Na+/K+ Pump Function and Mechanism

Lipid Digestion & Absorption into the Lymphatic System

ATP Synthase: Proton-powered Rotation

This video explores the use of desalination as a potential solution for managing water resources in Southern California and other coastal communities. It discusses the challenges of protecting marine ecosystems and the energy needed for...

Lactose Transporter How Does it Work

Water. It's an essential building block of life, constantly moving in a hydrologic cycle that flows in a continuous loop above, across and even below the Earth's surface. But water is also constantly moving through another cycle --...

Origins, insertions, innervation and functions of the deep extensors of the forearm.

In this video, we explore how NADH and FADH2 feed into and power the electron transport chain (respiratory chain) which is coupled with ATP synthesis.

In this video we are going to look at what viruses are. Viruses are a type of microorganism. They are too small to be seen with the naked eye: much smaller than bacteria, and about 100 times smaller than human cells. They come in many...

In this video, we will explore the differences between type I and type II diabetes mellitus after reviewing the normal physiology.

Neurons send signals through a mechanism called action potential. Action potentials are electrical signals that pass through the neuron’s axon. This causes the neuron to pass the signal to the next neuron. Action potentials are the...

Dr. Charles Limb, a surgeon and a musician, shows exactly how your brain takes in music and converts it to something you can understand.

Describes the mechanism of transport of water and minerals in plants. Explain movement of food from leaves to other plant parts.

This live-action video program is about white blood cells. The program is designed to reinforce and support a student's comprehension and retention of the term through use of video footage, photographs, diagrams and colorful, animated...
