Question 4: 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: Receptors are sensory structures present in whole body.

Functions of receptors:

• They sense 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.

Question 5: Draw the structure of a neuron and explain its function.

Solution: Neurons are the functional units of the nervous system. Three main parts of a neuron are axon, dendrite and cell body.

Functions of the three parts of a neuron:

Axon: It conducts messages away from the cell body.

Dendrite: It receives information from axon of another cell and conducts the messages towards the cell body.

Cell body: It contains a nucleus, mitochondria, and other organelles. It is mainly concerned with the maintenance and growth.
