Norepinephrine and epinephrine 128. What are three hormones that are secreted by a neuronal mechanism? oxytocin, ADH, and Epinephrine 129. By what mechanism are insulin and glucagon released? Humeral mechanism 130. By what mechanism are the hypothalamus and pituitary hormones released? Hormonal mechanism 131. What three things does the adrenal cortex secrete? Aldosterone Androgens/estrogen Cortisol 132. What does cortisol do? Stimulates fat and protein catabolism to use for gluconeogenesis. It also increases glucose levels. 133. What hormone increases protein and fat catabolism (breakdown) and increased blood glucose levels? Cortisol 8

Endocrine Flashcards 134. What hormone increases protein synthesis, and increases fat catabolism (breakdown) and increased blood glucose levels? Growth hormone 135. What two hormones suppress the immune system? Cortisol and prednisone 136. Why might a person be prescribed cortisol or prednisone? To suppress the immune system, in cases of autoimmune diseases like rheumatoid arthritis. 137. If a person is given high doses of cortisol, what will his own (endogenous) levels of cortisol be, and what would his ACTH-RH and ACTH levels be? Endogenous cortisol (the cortisol that his body makes) will be low. However, since they are given high levels of artificial (exogenous) cortisol, ACTH-RH will be low, and therefore, ACTH will be low 138. If the above person suddenly stopped taking his cortisol, what might happen? Addisonian crisis 139. What is Addisonian crisis? Low blood pressure and low blood glucose, to the point where it is a medical emergency 140. In Addison’s disease, what are the levels of cortisol? 141. What are the levels of ACTH? 142. What are the levels of ACTH-RH? Cortisol is low ACTH and ACTH-RH are high 143. Where is the problem in secondary adrenal insufficiency? Pituitary is the problem, not secreting enough ACTH 144. In secondary adrenal insufficiency, what are the levels of cortisol? 145. What are the levels of ACTH-RH? Cortisol is low ACTH-RH is high 146. What part of the body does aldosterone target, and what is its effect in that organ? 147. What is the effect of aldosterone on blood pressure? Kidney; increases the amount of salt and water absorbed. It increases blood pressure 148. What are androgens? Male sex-hormones (the hormones responsible for male secondary sex characteristics), especially Testosterone. It is a steroid hormone. 149. What are the secondary male sex characteristics? Deep voice, facial hair, and large thyroid cartilage. The testes enlargement is not a secondary sex characteristic. 150. What is the main steroid secreted by the adrenal gland that makes the sex hormones? DHEA 151. What are two of the hormones that DHEA can be converted into? Testosterone or estrogen 152. What does hyper-secretion of androgens cause in males?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
