Anterior Pituitary Endocrine Function

Diagram showing the HPA axis with CRH being released from the hypothalamus, stimulating the anterior pituitary to release ACTH, stimulating the adrenal glands to release cortisol which has effects on multiple effector target organs including the liver, muscle, bone, immune cells, CNS. Also demonstrates negative feedback action of cortisol on the hypothalamus and anterior pituitary and regulatory effects of stress and diurnal regulation
