What is the function of receptors in our body? Think of situations where receptors do not work properly. What problems are likely to arise?
Receptors are specialised tips of nerve cells that detect all information from our environment. They are usually located in our sense organs, such as the inner ear, the nose, and the tongue. For example, gustatory receptors detect taste while olfactory receptors detect smell. Their main function is to sense stimuli from the surroundings and send this information to the nervous system.
When receptors work properly, they help us detect urgent and dangerous situations, such as touching a hot object. This information is then transmitted through nerves, and the body can respond quickly through reflex arcs formed in the spinal cord.
If receptors do not work properly, several problems are likely to arise. The body would fail to detect important environmental signals. For instance, if the receptors in the skin are damaged, a person may not feel the sensation of heat from a hot object. As a result, the body cannot respond appropriately to dangerous situations.
This would disrupt the entire process of control and coordination. The nervous system would not receive proper information from the sense organs, and it would not be able to act through the muscles effectively. This could lead to injuries or harm because the body cannot sense or respond to threats in the environment.
Explanation
The answer draws directly from the textbook context which explains that receptors are 'specialised tips of some nerve cells' located in sense organs. The context specifically mentions gustatory and olfactory receptors. The problems arising from malfunctioning receptors are inferred from the context's discussion of how we detect hot objects and respond through reflex arcs. The textbook emphasizes that 'All information from our environment is detected by' these receptors, and without them, the nervous system cannot get information from sense organs to act through muscles.
