Take it from an expert: It’s weird to hear how your voice really sounds. But why does it sound different to you than everyone else. Hank explains -- in a deep, resonant voice.

Crash Course A&P continues the journey through sensory systems with a look at how your sense of hearing works. We follow sounds as they work there way into the ear where they are registered and transformed into action potentials....

We’ve all experienced it, that annoying pressure in our head when we’re flying in a plane or a storm front comes in, then it pops! Find out how this popping happens and things to avoid so you don’t harm your ears.

A video entitled “How Do Humans Hear Sound” which describes the parts of the human ear and how those parts send signals to the brain.

The tensor tympani muscle is a tiny muscle in the middle ear that helps dampens external sounds falling on the ear. The tensor tympani muscle originates from the Eustachian tube, which is also known as the auditory tube. From there, this...

Explore the process of hearing, from the collection of sound waves by our ears to the interpretation by our brain. The video discusses the ear's structure, including the outer, middle, and inner ear components like the cochlea and...

This first part of The Human Body series examines the structure of our skeleton and the function of our muscles. Viewers learn how our bones provide the rigid support necessary to hold any position, while our joints give us the...

In part three of a special series, the heroes take on another technical challenge to rescue the Apollo 11 mission control tapes for posterity and for academic research. HWHAP Episode 90.

In this video, we explore the structure and functions of the major branches of cranial nerve IX (the vagus nerve), specifically in the abdominal cavity.

In this video, I talk about how hearing takes place, starting with the soundwaves entering the ear, hitting the eardrum, and being transfered to the internal ear. Enjoy the process. I hope you can hear it :)

In this video, I show how Sound is accurately transferred to the inner ear. Since there is fluid inside the cochlea, impedance matching needs to take place. It happens due to the 1.3 to 1 ratio of movement between the maleus, incus and...

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.

In this video, we explore the fascinating world of mammals. From humans to whales and primates, mammals are a diverse group of organisms with unique characteristics. We delve into their evolutionary history, examining their jaw joint,...
