Explain the fluids filled in the chambers of eye , position and function ?
Aqueous humor : A watery fluid seen in the aqueous chamber [between cornea and lens] , oozes
from the blood. This fluid supplies nutrients and oxygen to cornea and lens.
Vitreous humor : A jelly like fluid filled with in the vitreous chamber [between lens and retina],
helps to maintain the shape of eyeball
Cornea is the Slightly projected transparent anterior part of the sclera.
Conjunctiva is the transparent membrane which protects the sclera, except the cornea.
Iris is the dark colored anterior part of choroid which contains the pigment melanin.
The aperture at the center of iris is Pupil.
The antagonistic muscles in the iris that regulate the size of eye pupil is Radial muscles (pupillary dilator) and Circular muscles (pupillary constrictor).
When bright light falls, the eye pupil Constricts due to the contraction of the circular muscles
The muscles, which adjust the curvature of eye lense seen behind the iris is Ciliary muscles.
The power of accommodation of the eye is the capacity of the eye to change the curvature of lens depending up on the distance between the the eye and the object by adjusting the focal length is called the power of accommodation of the eye
