The term "pars nervosa" is commonly used in neuroanatomy to refer to the posterior lobe of the pituitary gland, which is responsible for producing and releasing the hormone oxytocin. However, there are several other synonyms that can be used to describe this area. These include the posterior pituitary, neurohypophysis, neural lobe, and infundibulum. Additionally, some sources may refer to this area simply as the "back" or "rear" of the pituitary gland. Regardless of the terminology used, the pars nervosa plays an important role in regulating a number of bodily functions, including blood pressure, fluid balance, and reproductive behaviors.
