Hello,
1) Glucocorticoid (a type of corticosteroid) is secreted by the adrenal cortex. It is released under "long-term" stres; they do stimulate "gluconeogenesis" which is producing glucose from non-carbohydrate sources such as protein from skeletal muscle. I'm stuck on either "B" or "D." I would say "B" because, glucocortoids cause "anti-inflammatory" effects via suppressing the "immune system," thus making you vulnerable to viruses/bacteria. It could cause "hyperglycemia, which is excess glucose in bloodstream/circulatory system, if the glucose was secreted from the origins of liver and pancreas (probably in response to the pancreas's alpha cell's secretion of glucagon). "B."
2) C, opposes insulin's effect of decreasing blood sugar. If you were to skip a meal (low on blood sugar levels), glucagon would activate to re-establish blood-glucose homeostasis.
3) B, The Hypothalamus releases "Releasing hormones" that travel to the "Anterior Pituitary/adenohypophysis," which will stimulate the Anterior Pituitary to release it's own set of "tropic hormones," which will regulate activity of other glands/adrenal glands.
4) C, because the adrenal "medulla" is not a "true" endocrine gland and thus is more closely associated with the neuro-endocrine system.
5) D, astigmatism
