The given diagram demonstrates the internal structure and working of a neuron. Overall, a neuron consists of several components each of which perform certain specific functions. Right at the center of a neuron, there is a cell body known as soma. There are dendrites on its outer surface which receive messages and signals from other cells. These dendrites are connected to each other for rendering dissemination of messages. There is a certain section which connects upper and lower parts of a neuron called an axon which is primarily responsible for transferring messages away from the cell body to other neurons, muscles and glands. The electrical signal received from dendrites passes through the axon which itself is covered with an outer protective covering called Myelin sheath which facilitates rapid transmission of neural impulses. Finally once it passes through the axon, it reaches the terminal buttons which create junctions with other cells. This is the main mechanism of operation of neurons present in a human brain.

There have been significant improvements in the modern healthcare services which have facilitated invention of several innovative technologies and processes. With these advancements, the average life expectancy of an individual has risen in the last few decades. However, there is an age category which is old age that requires higher attention and care. As one grows more older with passage of time, there is a considerable decline in one's immunity levels, thereby resulting in various unwanted medical conditions and health risks. Consequently, there is a strong need within the current society to emphasize upon overall happiness and well-being of elderly people. Just like all other age groups, older people also require love, affection and care. With a steady rise in numbers of old people nowadays, it has become really essential for all of us to respect them. It has been observed in the modern society that older people are left alone quite frequently as a result of which their sense of loneliness and solitude increases which is detrimental for their mental health. Apart from this, aged people become highly prone to diseases like respiratory conditions, heart problems, diabetes, cancer, etc. if not kept in good shape. For example, there was a grandfather at a house who was completely alone and was not provided any sort of attention by his family members for a long time which resulted in deterioration of his health and ultimately he died. Therefore, it is a need of the hour for the entire public to enforce upon good health and balanced lifestyle of older people. One possible solution for this matter is that children and teenagers can perform a great role by devoting some of their time to their grandparents with an ethical approach and courteous manner and by abiding to their requests. Another possible solution would be that people must take their grandparents to most of their family outings in order to ensure that they keep getting refreshed at regular intervals of time as happiness can be a major contributer to fine fitness.
