MCH is synthesized in the magnocellular neurons in the lateral hypothalamus.
[53] documented that apelin-13 administration onto the hypothalamic supraoptic nucleus increased the firing rates of vasopressin cells but had no effect on the firing rate of oxytocin neurons, suggesting a local autocrine feedback action of apelin on magnocellular vasopressin neurons.
These optic nerve alterations are due to degeneration of axons and larger cells of the GCL and NFL [127] in the central and peripheral portions of the retina, which are involved in the magnocellular pathway and ensure greater optic nerve caliber [129].

The posterior or neurohypophyseal lobe of the pituitary contains the terminals of certain neurons (i.e., magnocellular vasopressin- and oxytocin-producing neurons) originating in two specific sections (i.e., the paraventricular nuclei [PVN] and supraoptic nuclei) of the hypothalamus.
