Tensor Tympani Muscle: Why Do You Hear A Rumbling Sound When You Close Your Eyes Too Hard?

The video explores the mysterious rumbling sound some people hear in their ears, caused by the tensor tympani muscle. It explains the anatomy of the ear, detailing the outer, middle, and inner sections. The tensor tympani muscle's role in dampening sounds and protecting the ear from loud noises is highlighted. The video also discusses the tympanic reflex and how some individuals can voluntarily control the tensor tympani muscle to produce a rumbling sound.

Which part of the ear is responsible for channeling sound waves to the eardrum?

• Inner ear

• Auditory nerve

• Middle ear

• Outer ear

What is the primary function of the tensor tympani muscle in the ear?

• To enhance hearing sensitivity

• To amplify sound waves

• To dampen sound vibrations

• To transmit sound to the brain

How does the tensor tympani muscle help in reducing the sound of chewing?

• By dampening vibrations

• By blocking sound waves

• By increasing ear pressure

• By amplifying external sounds

What is the response time of the tympanic reflex?

• 40 milliseconds

• 20 milliseconds

• 10 milliseconds

• 60 milliseconds

Why might some people hear a rumbling sound when they yawn?

• As a result of sound amplification

• Due to the contraction of the tensor tympani muscle

• Because of increased ear pressure

• Due to the movement of the eardrum
