Eye and four vision problems
All animals and plants are sensitive - they detect changes in their environment. This is one of the seven life processes. Any change that is detected is called a stimulus. If necessary, they then respond to stimuli in various ways. For example, if you are too cold, you may put a jumper on. Sense organs in animals have groups of receptor cells, which detect specific stimuli. Can you name some human sense organs and what they detect?
When the receptor cells of the sense organ are stimulated, they relay this information along nerve cells (neurons) to the central nervous system. There are different types of receptor cells which are sensitive to different stimuli.
Humans have five senses; sight, hearing, taste, touch, and smell.
Sight is the detection of light by our eyes. The different wavelengths of visible light give rise to different colors when interpreted by our brains.
This video will discuss four vision problems: color blindness, glaucoma, cataract, and diabetic retinopathy.
