MICROANATOMY

Detailed explanation-1: -Oxytocin (OT) is synthesized in the cell body of the OT cell in the hypothalamic paraventricular (PVN) and supraoptic nuclei (SON) and released into blood circulation from axon terminals in the neurohypophysis.

Detailed explanation-2: -Vasopressin and oxytocin are primarily synthesized in the magnocellular supraoptic and paraventricular nuclei of the hypothalamus and transported to the posterior pituitary.

Detailed explanation-3: -Oxytocin is synthesized in cell bodies of magnocellular neurons located principally in the paraventricular nucleus of the hypothalamus, is stored in the terminals of these neurons in the posterior pituitary, and is released from there into the peripheral circulation (Figure 1).
