From your understanding of the anatomy of the ear, what is the most likely explanation for a dog's ability to hear higher frequencies (pitch) ?

A) more ear bones for greater amplification
B) larger outer ears
C) a thinner and therefore more sensitive tympanic membrane (eardrum)
D) a wider range to the tectorial membrane and hair cells
E) a more advanced brain section devoted to hearing

Tympanic Membrane

A thin layer of tissue in the ear, also known as the eardrum, that vibrates in response to sound waves and transmits these vibrations to the ossicles within the middle ear.

Tectorial Membrane

The tectorial membrane is a structure located in the inner ear, specifically part of the cochlea, crucial for the auditory transduction process.

Higher Frequencies

Electromagnetic wavelengths that are shorter, resulting in greater oscillations per second, which are applied in various technologies like microwave and radio.
