Explain the structure of human eye with the help of well labelled diagram
Answers
Answer:
The human eyes are the most complicated sense organs in the human body. From the muscles and tissues to nerves and blood vessels, every part of the human eye is responsible for a certain action.
Explanation:
The parts of the eye that are visible externally include the following:-
Sclera: It is a white visible portion. It is made up of dense connective tissue and protects the inner parts.
Conjunctiva: It lines the sclera and made up of stratified squamous epithelium. It keeps our eyes moist and clear and provides lubrication by secreting mucus and tears.
Cornea: It is the transparent, anterior or front part of our eye, which covers the pupil and the iris. The main function is to refract the light along with the lens.
Iris: It is the pigmented, coloured portion of the eye, visible externally. The main function of the iris is to control the diameter of the pupil according to the light source.
Pupil: It is the small aperture located in the centre of the Iris. It allows light to enter and focus on the retina. I hope it helps you a lot .
