Definition
The pars nervosa is another name for the posterior pituitary gland, a section of the pituitary gland in your brain. Think of it as the hormone storage and release area. It specifically holds and releases hormones like vasopressin (for water balance) and oxytocin (for social bonding and childbirth). The pars nervosa itself does not produce these hormones; instead, it acts as a storage unit for hormones created in the hypothalamus. It's like a distribution center for crucial hormones. Without it, your body wouldn't be able to properly regulate water balance or social bonding.
