Fill in the blanks with approriate words.
In childhood growth is controlled by ......... hormone.

Answer 1

In childhood, growth is controlled by growth hormone and thyroxine.

The main hormones concerned with growth are pituitary growth hormone, thyroid hormone (thyroxine) and the sex hormones testosterone and estrogen.

In the child growth hormone is necessary for growth; without it dwarfism results. Thyroxine from the thyroid gland is necessary for normal growth, though it does not itself stimulate growth like growth hormone. Without thyroid hormone, however, cells do not develop and function properly, especially in the brain. Babies who lack thyroid hormone at birth are small and have insufficiently developed brains.

Sex hormones help in growth during puberty.
