Answers New Update
3 layer of the human eye - Answers -✔✔ fibrous, vascular, and inner layer
fibrous layer or - Answers -✔✔ sclera layer
Tough outer layer of eye
vascular layer or - Answers -✔✔ choroid layer
inner layer or - Answers -✔✔ retina layer
fibrous - Answers -✔✔ tough fibrous tissue
sclera - Answers -✔✔ white part of the eye
cornea - Answers -✔✔ Transparent front surface that protects the eye & acts as a lens
to focus light
vascular layer - Answers -✔✔ middle layer of eye: dense network of blood vessels
choroid - Answers -✔✔ pigmented melanin-rich layer prevents scattering of light
iris - Answers -✔✔ colored part of the eye
ciliary muscle - Answers -✔✔ Changes the shape of the lens for focusing on near and
distant objects
lens - Answers -✔✔ transparent body behind the pupil; focuses or reflects light rays on
the retina
inner layer - Answers -✔✔ inner most sensory layer of the EYE
retina - Answers -✔✔ contains various kinds of photoreceptors
rods - Answers -✔✔ receptors for night gives colorless vision when lights are low
cones - Answers -✔✔ receptors for day light or bright light
optic nerve - Answers -✔✔ paired nerves that sends visual info from the retina to the
brain
, retinal blood vessels - Answers -✔✔ blood vascular system of the retina including
branches and steams of the central retina artery and vein
general senses - Answers -✔✔ senses with receptors widely distributed throughout the
skin, organs and joints:
Temperature, pain, touch, pressure, vibration, and proprioception
special senses - Answers -✔✔ smell, taste, vision, hearing, equilibrium
photoreceptors - Answers -✔✔ light
chemoreceptors - Answers -✔✔ chemicals
pain receptors - Answers -✔✔ injury
thermoreceptors - Answers -✔✔ temperature change
mechanoreceptors - Answers -✔✔ movement or shape change
conjuctivitis - Answers -✔✔ "pink eye" inflammation or infection of the outer membrane
of eyeball and the inner eyelid
presbyopia - Answers -✔✔ or "old-sightedness" Become more farsighted as we grow
older. Caused by loss of elasticity of the lens of the eye.
cataract - Answers -✔✔ is a clouding of the normally clear lens of your eye
opaque - Answers -✔✔ Impossible to see through; preventing the passage of light
accomodation - Answers -✔✔ is a reflex action of the eye, in response to focusing on a
near object
normal vision - Answers -✔✔ light rays enter the eye and are focused into a clear,
upside-down image on the retina
myopia - Answers -✔✔ nearsightedness; eye enlongated, the image focused in front of
the retina rather than on it. Fuzzy image. Corrected with glasses.
hyperopia - Answers -✔✔ farsightedness; eye is shorter than normal. The image
focuses behind the retina, also producing a fuzzy image.
aqueous humor - Answers -✔✔ watery fluid in front of the lens ( in the anterior
chamber in front of the lens)
