Wednesday Quiz Prep For Eyes, Ears Flashcards
What is A? Name the part of the eye and describe what it does
Sclera – the white, outer protective layer of the eye.
What is B? Name the part of the eye and describe what it does
Choroid – the vascular layer providing nutrients to the retina.
What is C? Name the part and what it does
Retina – the innermost layer containing photoreceptors (rods and cones) for vision.
What is D? Name the part and what it does
Optic nerve – transmits visual information from the retina to the brain.
What is E? Name the part and what it does
Vitreous humor – the gel-like substance filling the space inside the eye.
What is A? What’s is its purpose?
Auricle or pinna - external part of ear
What is B and what’s is its purpose?
Semicircular canals - responsible for maintaining balance and detecting rotational movements of the head
What is C and what’s is its purpose?
Stapes or stirrup - smallest bone in the human body and one of the three ossicles in the middle ear
What is D and what’s is its purpose?
Cochlea - converts sound vibrations into electrical signals, which are sent to the brain via the auditory nerve.
What is E and what’s is its purpose?
Eardrum or tympanic membrane - Its primary function is to vibrate in response to sound waves, transferring these vibrations to the ossicles
What is A and what’s is its purpose?
Auricle or pinna - outer layer of ear
What is B and what’s is its purpose?
Malleus aka hammer - transmit sound vibrations from the eardrum to the incus
What is C? And what is its function?
Ear canal or external auditory / acoustic meatus - passageway for sound waves to reach the tympanic membrane (eardrum)
What is D and what’s is its function?
Semicircular canals - responsible for maintaining balance and detecting rotational movements of the head
What is E and what’s is its purpose?
Vestibules - responsible for balance, posture, and spatial orientation.
What is F and what’s is its function?
Stapes or stirrup
What is F and what’s is its function?
Stapes or stirrup - smallest bone in the human body and one of the three ossicles in the middle ear
What is G and what’s is its function?
Eardrum or tympanic membrane - primary function is to vibrate in response to sound waves, transferring these vibrations to the ossicles
What is H and what’s is its function?
Incus or anvil - It serves as a bridge, transmitting sound vibrations from the malleus to the stapes.
What is I and what is its function?
Cochlea - Converts mechanical sound waves into electrical signals that the auditory nerve sends to the brain for interpretation.
What is A and what’s does it do?
Vestibule - the vestibule is a central part of the inner ear that plays a crucial role in balance and spatial orientation.
What is B and what’s does it do?
Vestibular nerve - It is responsible for transmitting sensory information related to balance and spatial orientation from the inner ear to the brain.
What is C and what’s does it do?
Cochlear nerve aka auditory nerve, also responsible for transmitting auditory information from the inner ear to the brain.
What is D and what’s does it do?
Cochlea - Its primary function is to convert sound vibrations into electrical signals
What is E and what’s does it do?
Semicircular canal - plays a crucial role in maintaining balance and spatial orientation.
What is F and what’s does does it do?
Stapes or stirrup - The stapes plays a critical role in hearing by transmitting sound vibrations
What is F and what’s does does it do?
Stapes or stirrup - The stapes plays a critical role in hearing by transmitting sound vibrations
What is G and what’s does it do?
Incus or anvil - Receiving vibrations from the malleus and Transmitting these vibrations to the stapes
What is H and what does it do?
Malleus or hammer - It plays a vital role in the process of hearing by transmitting sound vibrations from the eardrum to the other ossicles.
What is I and what does it do?
Tympanic membrane or eardrum - plays a key role in the process of hearing by transmitting sound vibrations.
