The Correct Option is A

Solution and Explanation

Step 1: Understanding pars distalis.
Pars distalis is the anterior pituitary lobe responsible for secreting several trophic hormones.
Step 2: Hormones of pars distalis.
It secretes somatotropin (GH), prolactin, and corticotropin (ACTH).
Vasopressin (ADH) is synthesized in the hypothalamus and released from the posterior pituitary (pars nervosa), not pars distalis.
Step 3: Analysis of options.
(A) Vasopressin: Correct — not secreted by pars distalis.
(B) Somatotropin: Incorrect — secreted by pars distalis.
(C) Prolactin: Incorrect — secreted by pars distalis.
(D) Corticotropin: Incorrect — secreted by pars distalis.
Step 4: Conclusion.
The hormone not secreted by pars distalis is vasopressin.
