Match the parts of the eye with their functions:

Cornea = Transparent outer layer of the eye Iris = Controls the amount of light that enters the eye Sclera = White outer layer of the eye Choroid = Layer rich in blood vessels that supply the eye tissues with oxygen and nutrients

Match the components of the eye with their descriptions:

Conjunctiva = A transparent covering that lines the sclera and inner surface of the eyelids Ciliary body = A thickened part of the choroid towards the front of the eye Pupil = A black disk-like opening in the center of the iris Sclera = A complex, intricate, and fairly delicate structure

Match the functions with the corresponding sensory organs:

Sight = Eye Smell = Nose Touch = Skin Taste = Tongue

Match the parts of the eye with their characteristics:

Iris = Pigmented, muscular diaphragm Choroid = Rich in blood vessels that supply the eye tissues with oxygen and nutrients Cornea = Dome-shaped structure Sclera = White outer layer of the eye Signup and view all the answers

Match the following parts of the eye with their functions:

Cornea = Refraction of light Lens = Forming an upside-down image Ciliary body muscles = Changing the curvature of the lens Retina = Transforming light into nerve impulses Signup and view all the answers

Match the parts of the eye with their locations:

Cornea = Anterior part of the eye Choroid = Beneath the sclera Iris = Anterior part of the choroid Pupil = Center of the iris Signup and view all the answers

Match the effects with the corresponding actions of the pupil:

Increases the amount of light entering the eye = Dilatation of the pupil Decreases the amount of light entering the eye = Contraction of the pupil Changes the color of the eye = Amount of pigment present in the iris Increases the sensitivity of the eye = Thickness of the choroid Signup and view all the answers

Match the following structures in the eye with their descriptions:

Rods = Light sensitive, enable us to see in dim light Cones = Detect colour and fine details Optic nerve = A collection of nerves connecting the eye to the brain Vitreous body = A jelly-like substance filling the posterior compartment Signup and view all the answers

Match the following compartments of the eyeball with their contents:

Anterior compartment = Aqueous humor Posterior compartment = Vitreous body Iris = Muscles regulating light intensity Retina = Light sensitive nerve cells Signup and view all the answers

Match the following terms with their definitions:

Accommodation = The adjustment of the eye to focus on objects at varying distances Refraction = The bending of light as it passes through the cornea Pupil = The opening in the iris regulating light entry Iris = A transparent elastic body in the eye Signup and view all the answers

Match the following components of the eye with their locations:

Crystalline lens = Divides the eyeball into two compartments Retina = Innermost layer lining the rear three-quarters of the eyeball Optic nerve = Connects the rear of the retina to the brain Cornea = Outermost transparent layer of the eye Signup and view all the answers

Match the following eye structures with their functions:

Ciliary body muscles = Changing the shape of the lens Rods and cones = Transforming light into nerve impulses Aqueous humor = Maintaining pressure in the anterior compartment Vitreous body = Giving the eyeball its shape Signup and view all the answers
