1.Humans being have five main sensory organ, which are skin, nose,
tongue, ears and eyes.2. Sense detects stimuli, that is changes in surroundings (around us).
3. Five senses:
i. sight
ii. hearing
iii. touch
iv. taste
v . smell
4. Senses are part of the body called sensory organs.
5. Changes or object that can detect by our senses are called stimuli.
6. The ability of the sensory organs to detect stimuli is called senses.
7. All the sensory organs are complete with sensory receptors, that is the nerve endings that can detect stimuli.
8. Our sensory organs are used to detect stimuli (Singular: stimulus). A
stimulus is anything that causes a reaction in a living organism, e.g.
Pain, heat, sound, chemicals.
9. When a stimulus is detected, receptor cells in the sensory organ will be
triggered and generate impulses.
10. These impulses will be transmitted through the nerve and than to the
brain.
11. The brain will further process and interpret the impulse signals as
specific information than the organism has to respond to.
12. This information is than sent back to the sensory organ through the
nerve to provide responses
