1
a highly vascularized middle layer of the eye that supplies nutrients and oxygen to the retina. Contains the blood vessels.
What is the choroid coat?
focus light rays onto the retina, working in conjunction with the cornea to enable clear vision at varying distances
What is the lens?
the visible, external part of the ear (the pinna)
What is the auricle?
the primary cable connecting the eye to the brain, transmitting visual information via electrical impulses from the retina to the visual cortex
What is the optic nerve?
sweet, sour, salty, bitter, and umamI(savory)
What are the five basic tastes?
the light-sensitive layer of tissue at the back of the inner eye that acts like a camera sensor, converting light into neural signals, contains the rods and cones.
What is the retina?
thin, transparent, water-like fluid (98-99% water) that fills the anterior and posterior chambers of the eye
What is the aqueous humor?
the small, anvil-shaped middle bone (ossicle) in the mammalian middle ear, positioned between the malleus and the stapes
What is the incus?
control the amount of light entering the eye and reaching the retina.
What is the pupil?
play crucial roles in taste detection, creating the tongue's rough texture for manipulating food, and providing sensory information
What are the papillae?
commonly known as the "white of the eye," is a tough, opaque, fibrous protective outer layer that covers the majority of the eyeball. Composed predominantly of collagen fibers
What is the scelera?
transparent, dome-shaped outermost layer of the eye that acts as a protective barrier and the eye's primary focusing element
What is the cornea?
is a fluid-filled, snail-shaped spiral cavity within the inner ear that converts sound vibrations into neural signals, acting as the primary organ for hearing
What is the cochlea?
a sensory nerve responsible for hearing and balance, transmitting auditory and equilibrium information from the inner ear to the brain
What is the vestibulocochlear nerve or Acoustic nerve?
a visual phenomenon where the brain misinterprets images gathered by the eyes, causing perceived reality to differ from objective reality
What is an optical illusion?
the anatomical location on the retina where blood vessels enter and the optic nerve exits the eye, forming a natural "physiological blind spot" due to a lack of rods and cones
What is the optic disk or blind spot?
colored, muscular part of the eye that surrounds the pupil, functioning primarily to control the amount of light entering the eye
What is the iris?
a thin, translucent membrane separating the outer and middle ear, crucial for hearing by vibrating in response to sound waves.
What is the tympanic membrane?
It holds the lens in place and controls its shape, allowing the eye to adjust focus between near and far objects.
What is the ciliary body/muscle?
a primary healthcare professional providing comprehensive eye exams, diagnosing eye diseases, and prescribing glasses, contacts, and medications
What is an optometrist?
a small, central pit in the retina responsible for the sharpest, most detailed vision and color perception
What is the fovea centralis?
essential for maintaining the eye's spherical shape and structural integrity. It ensures clear vision by providing a transparent, stable medium for light transmission, acts as a shock absorber, and keeps the retina attached
What is the vitreous humor?
three tiny, fluid-filled tubes in the inner ear that are crucial for maintaining balance and sensing head movements.
What are the semicircular canals?
The "stirrup" shaped smallest bone, transmit sound vibrations from the incus (anvil) to the oval window, a membrane-covered opening to the inner ear, allowing for hearing
What is the stapes?
a naturally occurring optical phenomenon where light rays bend (refraction) through air layers of different temperatures, creating a distorted or displaced image of distant objects or the sky
What is a mirage?
