Question

Which of the following is transparent in nature?
A. Conjunctiva
B. Cornea
C. Iris
D. Both A and B

Answer 1

The human eye is an associate organ that reacts to light-weight in several circumstances. As an acutely aware organ, the human eye permits vision; rod and cone cells within the membrane enable conscious light-weight perception and vision, as well as colour differentiation and therefore the perception of depth. The human eye will distinguish regarding ten million colours.

Complete answer:
A. Conjunctiva could be a clear membrane that lines the eyelids. It protects the delicate tissue layer.
B. Cornea could be a clear layer that forms the front of eyes. It's the anterior portion of the sclerotic coat, a dense animal tissue that maintains the form of the eye and additionally protects it.
C. Iris is conjunctiva opaque and pigmented structure within the eye. It controls the scale of a pupil and so regulates the quantity of sunshine coming into the attention.
Hence, the mucous membrane and tissue layer are clear. So, each choice A and B are correct.

Additional information:
The cornea is the clear bulging surface ahead of the attention. it's the most refractive surface of the attention. The primary refractive surface of the attention Index of refraction: n = one.37. Normally clear and uniformly thick, Nearly avascular, Richly furnished nerve fibres, sensitive to foreign bodies, cold air, chemical irritation, Nutrition from body fluid and Tears maintain chemical element exchange and water content, Tears forestall scattering and improve optical quality.

Hence the correct answer is both option ‘A’ and ‘B’.

Note: Eyes are organs of the sensory system. they supply animals with vision, the power to receive and method visual detail, in addition to enabling many icon response functions that are freelance of vision. Eyes observe light-weight and convert it into electro-chemical impulses in neurons.
