Dr Matt & Dr Mike's Medical YouTube
Summary: Dr. Mike Todorovic & Dr. Matt Barton are Medical Educators from Australia that love teaching about the Human Body. We also have a podcast!! Dr. Matt & Dr. Mike's Medical Podcast Facebook: Dr Matt & Dr Mike's Medical Podcast Twitter: @drbartox @mickeytod @gubiosciences These brief concept captures are designed to supplement student learning for the following subjects: - Anatomy - Physiology - Pathophysiology - Pharmacology
In this video, Dr Matt explains everything you need to know about the triceps brachii muscle, including attachments, nerve innervation and action.
In this video, Dr Mike discusses the anatomy of the tricep extension. He also looks at whether you can isolate individual tricep heads through different exercises.
The Bicep Curl is a staple movement in the gym that targets the elbow flexors. These are: 1️⃣Brachialis 2️⃣Biceps brachii 3️⃣Brachioradialis . 1️⃣Brachialis - is the deepest of the elbow flexors and will be activated regardless of wrist/forearm position (i.e. supinated, pronated, neutral) and regardless of whether or not the movement is resisted. 2️⃣Biceps brachii - has origins on the scapula, which means it plays a small role in shoulder flexion. It inserts at the radial tuberosity but also creates a tendon-like sheath called the bicipital aponeurosis that covers the wrist flexors. This is important because when the forearm is supinated it creates an advantageous position for the biceps to flex. When the forearm is pronated, it puts the biceps in a disadvantaged lever arm. 3️⃣Brachioradialis - is a forearm supinator and pronator and aids in elbow flexion. Many ppl think that it is only activate in neutral and pronated flexion, however, it is more active in supinated flexion, but has an increasing contribution to elbow flexion in the pronated position because the biceps are disadvantaged in pronation. A flexion angle of 55 degrees in the semi-prone position seems to be the most optimal position to activate both the biceps and brachioradialis! This means if you want to get a strong bicep curl - use the EZ bar!!
In this video, Dr Matt explains the basic anatomy of the coracobrachialis muscle, including its attachments, action and nerve innervation
In this video Dr Matt explains the anatomy of the brachialis muscle, specifically its origin, insertion, nerve supply and action
In this video Dr Matt explains the attachments, nerve supply and action of the biceps brachii muscle.
In this video, Dr Mike gives a brief overview of the clavicle. - Location - Joints - Ligaments - Muscles
In this video, Dr Mike explains what components of filtrate get "reabsorbed" back into the body and what components of blood get "secreted" into the tubules of the nephron. He also shows you where along the nephron each substance gets either reabsorbed or secreted.
In this video, Dr Mike explains that every minute your kidneys receive 1,000mL of blood from the heart (20% of cardiac output). Of this 1,000mL around 400mL are cells (kidneys don't care about this) and 600mL is blood plasma (kidneys care about this). Only 20% of this 600mL is filtered into the nephron (120mL) every minute!! Let's take a look!
In this video, Dr Mike explores the various layers of filtration at the glomerulus. This includes: - fenestrated endothelia - basement membrane - podocytes Let's take a look at how they stop cells and proteins from being filtered into the tubules of the nephron.
What is chronic bronchitis? Why does it cause pulmonary hypertension? Why are people with chronic bronchitis called "blue bloaters"?
What is emphysema? How does it occur? Why is it called an obstructive airway disease? Why are emphysemics also called "pink puffers"?
In this video, Dr Mike explains how lipids (fats) are comprised of fatty acids and glycerol. He shows examples of short and long chain fatty acids, saturated, unsaturated, and polyunsaturated fatty acids. And the process of combining fatty acids with glycerol to form triglycerides.
What are phospholipids and how do they form cell membranes?
What are amino acids? How are they different from one another? How do they form proteins? How do proteins fold into functional structures?
