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....

The ability to recognize sounds and identify their location is possible thanks to the auditory system. That's comprised of two main parts: the ear, and the brain. The ear's task is to convert sound energy into neural signals; the brain's...

In this video, we explore the cochlea and the Organ of Corti by viewing it under light microscopy.<br/>

In this video, I talk about how the brain processes information on the different pitches that we hear. I'm warning you - it starts off a little scary, but by the end of the video, you will have a good idea of how we hear different...

In this video, I talk about the organ of corti, which is found on top of the basiliar membrane inside the cochlea. When the basilar membrane vibrates up and down, that causes the organ of Corti to move up and down, and the tectorial...

In this video, I show the details of how the bending of the stereocilia on the inner hair cells results in the release of neurotransmitters, which ultimately results in hearing. Enjoy.

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.
