with a large number of secretory granules in difference from
chromophobes which consist of cytoplasm with no secretory
granules. Pars intermedia is located between the pars distalis and
pars tuberalis and contains small basophilic cells. Pars tuberalis is
a part of the adenohypophysis around the infundibulum, composed
of basophilic cells that secrete gonadotrophs (luteinizing
hormone (LH) and FSH). The adenohypophysis is responsible
for the majority of the signaling hormones released into the
bloodstream through the well-developed hypothalamic–-
hypophyseal portal capillary system that drains into
hypothalamic–hypophyseal portal veins (Figure 1(a) and
1(b)). The posterior pituitary lobe (or neurohypophysis, consisting
of three distinct regions: pars nervosa (posterior lobe,
which includes Herring bodies and pituicytes), infundibulum
(pituitary stalk, which connects the hypothalamic and hypophyseal
systems), and median eminence (ME) (which is included as
