The removal of the anterior pituitary gland would affect the functioning of the Adrenal medulla, Pancreatic islet cells, and the Thyroid gland.

Here's why:

1. Adrenal Medulla: The anterior pituitary gland produces adrenocorticotropic hormone (ACTH) which stimulates the adrenal glands to produce and release cortisol. Without the anterior pituitary gland, the adrenal medulla would not receive the signal to produce these hormones.

2. Pancreatic Islet Cells: The anterior pituitary gland produces growth hormone which influences the actions of insulin and glucagon, hormones produced by the pancreatic islet cells. Without the anterior pituitary gland, the regulation of these hormones would be affected.

3. Thyroid Gland: The anterior pituitary gland produces thyroid-stimulating hormone (TSH) which signals the thyroid gland to produce and release thyroid hormones. Without the anterior pituitary gland, the thyroid gland would not receive the signal to produce these hormones.

The Parathyroid glands, however, would not be affected by the removal of the anterior pituitary gland as they are regulated by calcium levels in the blood, not by pituitary hormones.
