Oxytocin is a relatively small peptide hormone, composed of only 9 amino acids.It is synthesized in nerve cells in the hypothalamus in the form of a larger, precursor molecule, which is transported down the nerve fibres through the pituitary stalk to the posterior lobe.xytocin is secreted by the pituitary gland. Specifically, it is from the posterior pituitary, with posterior meaning the back or behind the pituitary gland.
Alternative names for oxytocin Alpha-hypophamine; manufactured versions â carbetocin, syntocinon and pitocin. What is oxytocin?
