The hyperglycemic effect results from the release of which hormone from the anterior pituitary gland?

The hyperglycemic effect is primarily associated with growth hormone, which is secreted by the anterior pituitary gland. Growth hormone plays a role in increasing blood glucose levels by promoting gluconeogenesis in the liver and reducing the uptake of glucose in certain tissues. This hormone helps to mobilize energy reserves during periods of stress or growth, which is crucial for maintaining adequate energy supply, especially during fasting or physical activity.

In contrast, other hormones mentioned do not originate from the anterior pituitary gland. Insulin is produced by the pancreas and functions to lower blood glucose levels. Glucagon, also secreted by the pancreas, works to increase blood glucose levels but is not a product of the anterior pituitary. Cortisol, a steroid hormone released by the adrenal glands, also increases blood sugar, but again, it is not tied to the anterior pituitary. Therefore, growth hormone is the primary hormone from the anterior pituitary that contributes to a hyperglycemic effect, accurately identifying it as the correct choice in this context.
