Consisting of the '''Pars Tuberalis and Pars Distalis''' this part has an embryological origin as an epithelial upgrowth from the foetal oral cavity called '''Rathke's Pouch'''. The anterior lobe of the adenohypophysis produces '''growth hormone (GH)''', '''follicle stimulating hormone (FSH)''', '''luteinising hormone (LH)''', '''adrenocorticotrophic hormone (ACTH)''', '''thyroid stimulating hormone (TSH)''' and '''prolactin (PRL)'''.

The pars tuberalis is a thin band of endocrine cells around the infundibular stalk. It is dense in '''melatonin''' receptors, and functions to regulate release of reproductive hormones according to season.
