front 15 Q: What does the lens do in the eye | back 15 A: The lens focuses light onto the retina to help with clear vision. |
front 16 Q: What is the ciliary body's role in the eye | back 16 A: The ciliary body produces aqueous humor and helps to focus light by altering the shape of the lens. |
front 17 Q: What is aqueous humor | back 17 A: Aqueous humor is the clear, watery fluid produced by the ciliary body that occupies the space between the cornea and the lens. |
front 18 Q: What is the function of the vitreous humor | back 18 A: The vitreous humor is a jellylike material that fills the space behind the lens and helps maintain the eye's shape. |
front 19 Q: What are rods responsible for | back 19 A: Rods are responsible for night (black and white) vision and are located mostly on the periphery of the retina. |
front 20 Q: What are cones responsible for | back 20 A: Cones are responsible for color vision and are most numerous in the fovea region of the retina. |
front 21 Q: What is the fovea and why is it important | back 21 A: The fovea is the center of the visual field, where humans see the sharpest vision due to the high concentration of cones. |
front 22 Q: What is the blind spot in the eye | back 22 A: The blind spot is the point where the optic nerve leaves the retina, and it contains no photoreceptors. |
front 23 Q: What is the function of the pinna (auricle) | back 23 A: The pinna is the external surface of the ear that helps capture sound waves. |
front 24 Q: What does the auditory canal do | back 24 A: The auditory canal is the passage that leads from the outside to the eardrum. |
front 25 Q: What is the role of the tympanic membrane (eardrum) | back 25 A: The tympanic membrane vibrates in response to sound waves, transmitting sound to the middle ear. |
front 26 Q: What is the function of the Eustachian tube | back 26 A: The Eustachian tube connects the middle ear to the pharynx and equalizes air pressure in the middle ear with the atmosphere. |
front 27 Q: What is the function of the malleus (hammer) | back 27 A: The malleus is the first ossicle in the middle ear and directly attaches to the eardrum to transmit vibrations. |
front 28 Q: What is the function of the incus (anvil) | back 28 A: The incus is the second ossicle, located between the malleus and stapes, and helps transmit sound vibrations. |
front 29 Q: What is the role of the stapes (stirrup) | back 29 A: The stapes is the third ossicle in the middle ear and attaches to the oval window, leading to the inner ear. |
