Pinealocyte astrocyte
WebFunction [ edit] Pituicytes are similar to astrocytes, another type of glial cell. Their main role is to assist in the storage and release of hormones of the posterior pituitary. Pituicytes surround axonal endings and regulate hormone secretion by releasing their processes from these endings. [1] WebPinealocytes are identified histologically using agents that stain for enzymes involved in melatonin synthesis and for some proteins involved in phototransduction. 36 In this …
