705. Why do our eyelashes and eyebrows never continue to gow unlike hair on our head?

☞ The cilia or eyelashes are hairs situated on the margin of the lids. They are dispensed in two rows, totalling about 100-150 cilia in the upper lid and half the number in the lower lid.
The pigmentation of the cilia is deeper than that of the scalp hair throughout adult life.
The average life of each cilium is from 3-5 months after which it falls out and a new one grows in to take its place. If the cilia is pulled out the new one replacing it reaches full size in about 2 months. Since the life of the cilia is only 3-5 months, it does not grow as long as scalp hairs.

☞ Small organs in the skin, called follicles produce hair. All follicles go through a three-stage cycle- anagen is a period when the hair grows actively; catagen is marked by a short phase during which growth winds down; and finally telogen is the stage of rest. The cycle is completed at the end of telogen and the hair falls and a new hair begins to grow.
Scalp hairs (hairs on the head) have the longest anagen period - four to eight years during which they grow and have just two to four months of rest stage.
Eyelashes, arm hair, and most other hairs on the body have significantly shorter growth periods of one to six months, followed by a 2-4 month period of rest.

704. Why do houseflies rub their front legs together?

Housefly (Musca Domestica) is a common insect found in all places. It has a very short life span. Adult houseflies feed on human and animal food and waste materials and often use buildings as shelter.
The housefly is well adapted in structure and behaviour to transmit disease causing organisms from place to place.
The body of a housefly is covered with fine hairs and bristles that readily pick up filth particles.
At the base of each leg there is a cushion-like structure covered with granular hairs.A sticky secretion which excretes from the granular hairs gathers bacteria and other micro organisms which stick to the legs. In order to clean its body and the legs, houseflies rub their legs together. It is estimated that whenever a housefly rubs its legs, lakhs of bacteria are discharged from the legs for each rubbing.
 
703. Why does pepper make you sneeze?

A sneeze is a reflex that is triggered when nerve endings inside the mucous membrane of the nose are stimulated.
Pepper, be it white, black, or green, contains an alkaloid of pyridine called piperine. Piperine acts as an irritant if it gets into the nose. It stimulates (or irritates) the nerve endings inside the mucous membrane. This stimulation will cause you to sneeze. Actually, the nose wants to kick out this irritant and the only way it knows how to do this is by sneezing.
