The neurohypophysis, or posterior pituitary, consists of the pars nervosa, median eminence, and infundibular stalk. The pars distalis, however, is a part of the adenohypophysis (anterior pituitary) and is not a component of the neurohypophysis. Therefore, the pars distalis is the part that does not belong to the neurohypophysis.
Components of Neurohypophysis: Pars nervosa: Stores and releases hormones produced by the hypothalamus.
Median eminence: Connects the neurohypophysis to the hypothalamus.
Infundibular stalk: Acts as a conduit for hormone transportation.
Conclusion: Pars distalis is part of the anterior pituitary and not the neurohypophysis.
