Question

Neurohypophysis is differentiated into the following parts except:

• A. Pars nervosa
• B. Pars distalis
• C. Median eminence
• D. Infundibular stalk

Hint:

The neurohypophysis primarily functions in the storage and release of hormones like oxytocin and vasopressin, which are produced in the hypothalamus.

Answer 1

The Correct Option is B

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.
