Which of the following hormones could possibly be released from the cells indicated by the arrows in the image above? A. adrenocorticotropic stimulating hormone (ACTH) B. calcitonin C. insulin D. parathyroid hormone (PTH) E. prolactin (PRL) Krafts 11. A 32-year-old female presents with hypertension, hyperglycemia, and depression. She is found to have an ACTH-secreting pituitary tumor.
