Fluid Statics
MCAT Basics (from MedSchoolCoach)
This MCAT Basics episode covers fluid statics (fluids standing still). It begins with different fluid properties, including surface tension, vapor pressure, adsorption and absorption, adhesion and cohesion, and Henry's law. Next, it discusses several important fluid statics concepts: static fluid pressure, Pascal's law, gauge pressure vs absolute pressure, osmotic pressure, and buoyancy.

The Muscular System
MCAT Basics (from MedSchoolCoach)
This MCAT BAsics episode covers the muscular system. It begins with the differences and similarities between the three types of muscle (smooth, cardiac, and skeletal). Then, the podcast explores the basic structure of a skeletal muscle cell and the various organelles unique to this cell type, including the sarcolemma, sarcoplasm, myofibrils, sarcomeres, and more. Next, it discusses three main differences between Type 1 and Type 2 muscle fibers. Finally, it delves into muscle contraction, starting at the neuromuscular junction and ending with the shortening of sarcomeres, which causes muscle...

Social Stratification
MCAT Basics (from MedSchoolCoach)
This MCAT podcast covers social stratification. It begins with a definition and examples of many terms related to social stratification and inequality, including prejudice, discrimination, stereotype, stereotype threat, status (ascribed vs achieved), power (six different types to know), social capital (and other forms of capital), gentrification, and poverty. The discussion then moves on to social class and the social gradient in healthcare. Visit for more help with the MCAT.

The Cell Cycle
MCAT Basics (from MedSchoolCoach)
In this episode, we explore the different phases of the cell cycle: Interphase (G1, S, G2) and the M phase (mitosis). Next, we discuss the regulation of the cell cycle and the key checkpoints that ensure its proper progression. Finally, we touch on how dysfunction in the cell cycle can lead to diseases, particularly cancer. This material is likely to appear in the Bio/Biochem section of the MCAT.

Isomers
MCAT Basics (from MedSchoolCoach)
In this episode, we delve into three common types of isomers that you are likely to encounter on the MCAT: structural isomers, geometric isomers, and stereoisomers. We start by defining each type of isomer, providing clear and concise explanations to ensure a solid understanding. Next, we present common examples of each isomer type to illustrate their unique characteristics. Finally, we discuss real-world applications and scenarios where these isomers are relevant, particularly in the context of the MCAT. This material will appear in the Physical Chemistry section of the MCAT and may...

Emotion and Motivation
MCAT Basics (from MedSchoolCoach)
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...

Cardiovascular System + Fluids
MCAT Basics (from MedSchoolCoach)
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...

info_outlineThis episode is packed with essential high-yield information for your MCAT prep, covering the biological, physiological, and psychological aspects of sleep. We’ll explore various sleep theories, like the Memory Consolidation and Brain Plasicticity Theories, and even discuss the controversial “Sleeping When You Die” theory. We’ll also delve into dream theories, including Freud’s interpretations and the Activation Synthesys Hypothesis. Plus, we’ll address common sleep disorders such as insomnia, sleep apnea, and narcolepsy, alongside the effects of different drugs on your sleep patterns.
We’ll cover critical brain structures involved in sleep, such as the hypothalamus and the suprachiasmatic nucleus, and break down the stages of sleep measured through EEG, EMG, and EOG.
