PRACTICAL TASK 14
Theme: THE STRUCTURE OF THE HUMAN EYE

Task № 1
Match each of the part of the eyes with its function correctly:

Part of the eye Function

Control the amount of light entering the
1.Iris retina

Controls the size of pupil
2.Eye lens

Focuses light on the retina
3.Pupil

Prevent light reflection and provides nutrients
4.Ciliary muscle and oxygen to eye cells

5.Cornea Refracts and focuses light onto the retina

6.Choroid Change the thickness of the eye lens

Contains photoreceptors that detects light
7.Sclera stimuli and generates nerve impulse

Send nerve impulses from the retina to the
8.Retina brain to be interpreted

Protect and give shape to the eye
9.Optic nerve
Not sensitive to light because there is no
10.Aqueous humour and photoreceptor and is the exit of all optical
Vitreous humour nerve fibers
Maintain the shape of eye and focus
11.Blind spot light onto the retina
Most sensitive to light because it contains
12.Yellow spot many photoreceptors

13.Suspensory Transparent membrane that protects
ligament the front of the sclera

14.Conjunctiva Hold the eye lens in its position
