What is the function of receptors in our body? Think of situations where receptors do not work properly. What problems are likely to arise?
Solution and Explanation
Receptors are chemical structures based on proteins that receive and relay signals, and they can be integrated into biological systems. These receptors are distributed throughout the body; for instance, the skin contains various types of receptors, including mechanoreceptors and thermoreceptors.
Functions of receptors:
→ They sense the external stimuli such as heat or pain.
→ They also trigger an impulse in the sensory neuron which sends message to the spinal cord.
When the receptors are damaged, the external stimuli transferring signals to the brain are not felt.
For example, in the case of damaged receptors, if we accidentally touch any hot object, then our hands might get burnt as damaged receptors cannot perceive the external stimuli of heat and pain.
The result is that the body would not respond to changes in the surroundings.

Concepts Used:
Neural Control and Coordination
Neural System:
Neurons are the most specialised cells in the nervous system of all animals, and they are responsible for detecting, accepting, and conveying numerous types of motives. The neurological system of low-spinal animals like Hydra is incredibly simple, consisting of a network of neurons. When the brain of an insect comprises a vast number of ganglia and neural tissues, it is optimally structured.
Coordination System:
Coordination is the process by which two or more organs work together to accomplish each other's duties. Increased muscle activity increases the supply of oxygen and the demand for energy while we exercise. When we cease exercising, our nerves, heart, lungs, and kidneys all return to normal. As a result, all of the organs' functions are properly integrated in order to conduct the exercise and supply the appropriate conditions while exercising. Similarly, in the human body, the neurological and endocrine systems work together to coordinate all of the organ activities.
