In this episode, we cover motivation and emotion–key concepts that will show up in the Psychological, Social, and Biological Foundations of Behavior section of the MCAT.

We start with the difference between intrinsic and extrinsic motivation. We then go into various theories including evolutionary, arousal, drive-reduction, incentive, three needs theory, Maslow’s hierarchy, and the correlation between harmful behaviors like addiction and motivation.

Lastly we get into emotion, covering its three components, the relationship between emotion and the brain, and an array of theories including evolutionary, James-Lange, Cannon-Bard, Schachter-Singer, Lazarus, and facial feedback theories. Additionally, we discuss the influence of culture on emotion and delves into emotional disorders.

In this episode, we focus on the cardiovascular system and its connection to fluid mechanics. Beginning with an exploration of cardiovascular anatomy, the discussion covers various aspects of the heart: its function, contraction mechanism, the diverse cell types found within it, and its essential role in regulating blood pressure.

Finally, in the latter part of the episode, several fluid mechanics topics pertinent to the MCAT and their application to the cardiovascular system are addressed. These include total peripheral resistance, viscosity, the continuity equation, and the Bernoulli equation, offering insights into their relevance in understanding cardiovascular dynamics.

This podcast addresses translational motion. First, vectors are covered. Then, the variables of acceleration, velocity, and position are discussed. Next, the host discusses the relationship between those three variables. Finally, it covers free fall, projectile motion, air resistance, and friction.

This podcast explores cell organelles, organized into five categories: organelles found in all cells, eukaryotic cells, plant and bacterial cells, human and bacterial cells, human cells only, and plant cells only. The organelles discussed include ribosomes, vacuoles, cytoskeleton, plasma membrane, peroxisome, proteasome, nucleus, nucleolus, smooth and rough endoplasmic reticulum, Golgi apparatus, lysosome, cell wall, flagella, mitochondria, melanosome, and chloroplasts.

This podcast discusses chemical kinetics and solubility. It begins with an exploration of kinetics, including the general concept, collision theory, rate laws, and the Arrhenius equation. Next, it delves into solubility, covering the general concept, solubility product (Ksp), the common ion effect, selective precipitation, and Henry’s law.

This podcast focuses on the eye. It begins with a brief overview of the eye's anatomy and physiology. The discussion then shifts to rods, cones, and the phototransduction pathway. The final section addresses perception.

Key topics include visual field processing, differences between binocular and monocular cues, and feature detection (covering both Magno and Parvo pathways).

To continue our discussion on the immune system, in this episode, we will cover the second type of immune system – the adaptive immune system.

We start with covering some vocabulary that you’ll need to know to understand the immune system, then we move into the cells that make up the adaptive immune system. Then we break down the two branches of the adaptive immune system - humoral immunity including the discussion of B cells and cell-mediated immunity highlighting T cells.

Don’t miss our previous episode on the other type of immune system, the innate immune system.

The immune system is split up into two main categories - the adaptive immune system and the innate immune system.

This episode will cover the intricacies of the innate immune system beginning with an overview of its constituent cells. We will then explore three pivotal elements of the system: anatomical barriers, the general inflammatory response, and the complement system. This will show up in the bio/biochem section of the MCAT.

For additional reading on this topic, you can refer to the NIH’s Innate Immune System paper.
