[@lorenahur2386]

Thank you so much for all the videos! Saving my life right now. Wish my professor can teach like this.

As a person who works in pathology (histology specially) when he said he got formalin to the eye I screamed. Thanks for these lectures Dr. Keyte, they are extremely helpful.

[@joannarodriguez326]

Clear and detailed explanations. This is very helpful. Thanks a million!

If I am only thinking right at 10:50 sensory receptors for balance are found i the vestibule and not semicircular canals. You even went further and said the utricles and the saccules which are found in the vestibule. The semicircular canals are for rotation and vestibule for equilibrium and balance right??

When the sound energy exits the round window strikes the tympanic membrane from the other side, would that also cause the tympanic membrane to vibrate? Is that why a particular loud sound might cause ringing? The sound energy travels back and forth until the energy eventually dissipates.

[@JeffKeyte]

Interesting theory, but I believe the round window is quite a bit stiffer, and after traveling through all of that perilymph there wouldn't be sufficient energy to move enough air in the middle ear to create that effect. Ringing from loud sounds like actually caused by hair cell fatigue or even damage. When they don't fire properly we experience ringing.

[@kassandrafelling4909]

Wish I would of found this earlier! It would helped me than my own anatomy teacher.

[@gousayalkhazmari8450]

great lecture if i may ask what's the name of the reference book you are using.

[@JeffKeyte]

Martini's "Visual Anatomy and Physiology" is the textbook we use. It is published by Pearson I think.

that was a great teaching. y was someone coughing in ur class? do u teach biochemistry also

[@thor3793]

You keep saying movement of endolymph. Scala tympani and scala vestibuli is filled with perilymph, not endolymph

[@JeffKeyte]

+Christian Thorvaldsen You are correct. Thanks for the pick-up.
