In this video, we review GTOs and discuss the functions of muscle spindles in providing proprioceptive information about muscle length and preventing stretch-related muscle injuries.

In this video, we explore the fascinating control center of our bodies - the brain. We learn about reflexes, motor systems, and the various motor areas in the brain that allow for precise voluntary control. Additionally, we discover the...

In this video, we introduce neck pain and several important risk factors for developing neck pain along with how to conceptually think about the prognosis for a patient with neck pain.

Overview of the muscles of the pharynx and related structures.

In this video, we explore the functions of all 6 extrinsic eye muscles and the cranial nerves innervating and controlling each.

Myasthenia Gravis | Pathophysiology, Signs & Symptoms, Diagnosis, Treatment



Myasthenia Gravis is an autoimmune condition involving the production of autoantibodies against particular parts of the muscle and neuromuscular...

Anatomy and functions of the tibialis anterior muscle shown with 3D model animation.

Through video, animation and graphics students will discover how the respiratory and circulatory systems work together to help keep us alive through a process called cellular respiration. A close-up look at the components of our blood:...

Trigeminal Neuralgia (“Severe Facial Pain”) | Causes, Pathophysiology, Symptoms, Diagnosis, Treatment



Trigeminal neuralgia is a relatively rare neurological condition involving compression of the trigeminal nerve. The...

Leonardo da Vinci spent a lot of time dissecting cadavers and studying the structure of muscles in the body. He had a particular interest in how emotions are translated into expression using the facial muscles. He was also interested...

Fishes survive underwater pressure as they do not breathe through their lungs. Therefore, they do not have air pockets that can be compressed due to the high pressures. However, fish aren’t the only creatures found at such incredible...

Anatomy and functions of the obturator externus muscle shown with 3D model animation.

This tutorial focuses on muscles that comprise the medial compartment of the thigh.

Anatomy and functions of the sartorius muscle shown with 3D model animation.

Neuroengineer Rajesh Rao of the University of Washington is developing brain-computer interfaces, devices that can monitor and extract brain activity to enable a machine or computer to accomplish tasks, from playing video games to...

How do muscles actually contract? There's a lot involved in the process. And in this video, we talk about muscle contraction at the molecular level. We'll discuss sarcomeres, actin, myosin, the muscle action potential and the roles of...

It is better to sip water rather than chugging it down. That’s why certain water bottles have a narrower opening than required. Imagine a case where you have a sudden urge to drink water (obviously, you’re thirsty). You gulp down a glass...

In this video, Leslie talks about the bohr effect, showing how a combination of an increase in CO2 production, combined with a reduction in pH results in an increase in Oxygen delivery by Hemoglobin.

In this video, Leslie talks about the pressure changes in the Thoracic, Pleural and Pulmonary cavity and how they change during breathing. Enjoy!

Anatomy and functions of the plantaris muscle shown with 3D model animation.

Anatomy and functions of the semitendinosus muscle shown with 3D model animation.

Contents of the female pelvis, including the viscera and perineum.

In this video, my wife helps me to demonstrate how reflexes work at the level of the neurons. We look at both the Knee jerk and eye blink reflexes and the mechanism underlying both.

In this episode, I start talking about skeletal muscle contraction, by giving a general introduction into how muscle contraction happens. I deal with how the action of actin and myosin in the sarcomere results in movement. Enjoy!
