What Makes Us Grow Taller

The stature to which each of us grows is predetermined in our genes. Tall parents tend to produce tall offspring. And growth also depends on endocrine and nutritional factors.

Also Growth hormone promotes growth during childhood and adolescence, but slackens off when maturity is attained. Too much growth hormone, as is secreted by pituitary tumors, induces gigantism, while too little causes dwarfism. The adolescent growth spurt is correlated with the surge of sex hormones(testosterone and estrogen) secreted at the time of puberty.

Human beings take longer to grow up than any other animal. This is correlated with our considerable longevity but has probably evolved as an adaptation to our higher intelligence.

Most teens can expect to grow a total of about 7 to 10 inches during puberty before they reach their full adult height. Each person is a little different, so everyone starts and goes through puberty on his or her body's own schedule. Those who start a little later than their friends will usually continue to grow a little later, too.

Hopefully students you have got answers to your queries. Good bye for now.
