Anatomy - Hearing (Part 1) - The Pathway of Sound up to the Oval Window

The video explores the physiology of hearing, focusing on how sound waves are detected by the brain. It explains the nature of sound waves as pressure gradients moving through various mediums and follows their path through the ear. The video details the role of the tympanic membrane and auditory ossicles in amplifying sound vibrations, leading to the cochlea where further processing occurs. The video concludes with a preview of the next video, which will cover the physiology of the cochlea in more detail.

What is the primary function of sound waves in the context of hearing?

• To create light

• To disturb particles in a medium

• To generate heat

• To produce electricity

Which part of the ear do sound waves first enter?

• Tympanic membrane

• Cochlea

• Auditory ossicles

• External acoustic meatus

What is the common name for the tympanic membrane?

• Ear canal

• Stapes

• Eardrum

• Cochlea

Which of the following is NOT an auditory ossicle?

• Cochlea

• Stapes

• Incus

• Malleus

What is the function of the auditory ossicles?

• To absorb sound vibrations

• To reflect sound vibrations

• To amplify sound vibrations

• To decrease sound vibrations

What is the name of the fluid inside the cochlea that vibrates?

• Blood plasma

• Perilymph

• Endolymph

• Cerebrospinal fluid

What is the purpose of amplifying vibrations before they reach the cochlea?

• To change the frequency of sound

• To cool the ear

• To enhance the detection of vibrations

• To reduce noise
