Bio 130 Ear Anatomy Quiz

The correct answer is K because the cochlea is a spiral-shaped, snail-like structure in the inner ear that is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. It contains the sensory cells called hair cells, which are responsible for detecting sound waves and transmitting them to the auditory nerve. Option K is the only letter that resembles the shape of a cochlea, with its curved and spiral design.

The correct answer is B because the eardrum, also known as the tympanic membrane, is located between the ear canal and the middle ear. It is a thin, translucent membrane that vibrates when sound waves enter the ear, transmitting these vibrations to the middle ear. The other options (E, F, A) do not represent the eardrum.

The correct answer is "I" because cranial nerve VIII is the vestibulocochlear nerve, which is responsible for transmitting sound and balance information from the inner ear to the brain. The letter "I" is the Roman numeral representation for the number 1, which corresponds to the correct answer.

The correct answer is I because the auditory nerve is responsible for transmitting sound information from the cochlea to the brain. This nerve is part of the auditory system and plays a crucial role in our ability to hear and process sound.

The correct answer is H because the ampulla of vestibular is a dilated portion of the membranous labyrinth located in the inner ear. It is responsible for detecting rotational movements of the head and is involved in the sense of balance and spatial orientation.

The correct answer is L because the cochlear branch is responsible for transmitting auditory information from the cochlea to the brain. Among the given options, L is the only letter that represents the cochlear branch.
