Question

which of the following hormones is most often produced excess from the anterior pituitary?
somatotropin
prolactin
thyroxine
acth

Explanation:

1. Recall the hormones produced by the anterior pituitary: Somatotropin (Growth Hormone), Prolactin, ACTH (Adrenocorticotropic Hormone), etc. Thyroxine is produced by the thyroid gland, so it's eliminated.
2. Among the anterior pituitary hormones, Prolactin excess (hyperprolactinemia) is relatively common, often due to factors like prolactinomas (tumors in the anterior pituitary that secrete excess prolactin). While somatotropin excess causes acromegaly/gigantism and ACTH excess causes Cushing's disease, prolactin excess is more frequently encountered clinically.

Answer:

Prolactin (the option corresponding to "Prolactin")
