Suppose you have a death certificate and gives the date of death. Suppose it does not give the date of birth but instead gives the age rather precisely -- so many years, so many months, and so many days. You would enter the date of death for the second event and the precise age for the elapsed time. The first event would then give the date of birth.
1 Oxytocin is a neuropeptide produced in the hypothalamus and secreted by the pituitary gland. 2  Oxytocin is released during sex, childbirth and lactation to aid reproductive functions. 3  This neuropeptide exerts multiple psychological effects, influencing social behavior and emotion.
In the hypothalamus, oxytocin is made in magnocellular neurosecretory cells of the supraoptic and paraventricular nuclei, and is stored in Herring bodies at the axon terminals in the posterior pituitary. It is then released into the blood from the posterior lobe (neurohypophysis) of the pituitary gland.
