That hair is called lanugo, and it's normal. Lanugo is the first hair the body makes, and in utero it covers the developing child like fuzz on a peach, if that peach had spent the last five months kicking its mother when she was trying to sleep and jumping up and down on her bladder.
Pineal Gland Function. The pineal gland has several critical functions including secretion of melatonin the hormone that causes sleepiness and regulation of certain endocrine functions. The gland also helps the body to convert signals from the nervous system to signals in the endocrine system.
What is the Pineal Gland? The pineal gland is a very small gland that is shaped like a pine cone. It is about one centimetre long and it is located between the two hemispheres of the brain and above the third ventricle of the spinal column. The pineal gland is made up of pinealocytes and glial cells.
