Lab Final Ear Flashcards
What is A and its function?
Auricle - external part of the ear, funnels sound waves to auditory canal
What is B and its function?
External acoustic meatus - is a tube-like structure of the outer ear that serves as a passageway for sound waves to reach the eardrum
What is C and its function?
Elastic cartilage - helps with flexibility
What is D and its function?
Tympanic membrane - plays a crucial role in hearing by transmitting sound waves to the ossicles in the middle ear.
What is E and its function?
Tympanic cavity - It connects the external ear to the inner ear and contains structures responsible for transmitting sound vibrations.
What is F and its function?
Oval window - transmission of sound vibrations from the middle ear to the fluid-filled cochlea of the inner ear.
What is G and its function?
Round window - allowing movement of fluid within the cochlea, facilitating the transmission of sound waves.
What is H and its function?
Vestibule label - It plays a critical role in balance and spatial orientation by housing structures and receptors responsible for detecting linear acceleration and head position.
What is I and its function?
Eustachian tube - It plays an essential role in maintaining ear health and proper hearing.
What is J and its function?
Cochlea - It converts sound waves into electrical signals that can be interpreted by the brain.
What is K and its function?
Eustachian tube - essential for equalizing pressure on both sides of the tympanic membrane, as well as for draining fluid from the middle ear.
What is L and its function?
Bony labyrinth - The bony labyrinth is a complex, rigid, and hollow structure located within the inner ear. It is part of the temporal bone and houses the essential structures responsible for hearing and balance. It is filled with a fluid called perilymph and surrounds the membranous labyrinth, which contains endolymph.
