The actions of the individual hormones are discussed in further detail in the chapters dealing with their target glands: hormonal control of the thyroid, parathyroid and adrenal glands is discussed in Chapter 16, hormonal c...

The neuronal and epithelial parts of the hypothalamo-hypophyseal complex (proximal and distal neurohypophysis, adenohypophysis) have in common the task of message transfer.

The released substances reach ...
