The neurosecretory cells of the hypothalamus and the pituitary gland form the foundation for the functions of the endocrine system. The hypothalamus and the pituitary gland control endocrine function via the hormones they synthesize and secrete. These hormones are peptides, or small proteins, by molecular structure. Tutorial 36 illustrates and discusses the activity of the neurosecretory cells, the interactions that occur between the hypothalamus and the pituitary, and the unique functions carried out by two distinct regions of the pituitary.
