pineal body
pineal body (epiphysis) In vertebrates other than humans, an outgrowth of the fore brain that secretes hormones affecting reproductive behaviour. In mammals that have a regular oestrus cycle its secretion of melatonin inhibits development of the gonads; the pineal may have a similar function in human children.
