Exam 15: The Endocrine System

Figure 15.2 Using Figure 15.2, match the following hypothalamic hormones with the pituitary hormone targets: -Growth hormone

Figure 15.2 Using Figure 15.2, match the following hypothalamic hormones with the pituitary hormone targets: -Adrenocorticotropic hormone

A 25-year-old male was admitted to the medical/surgical unit with a blood glucose of 600 mg/dl. On assessment, the nurse observed his breathing was deep and rapid, and his breath smelled of acetone. His face was flushed and his skin was dry. His pH was low. Describe the physiological response that is occurring.

Virtually all of the protein or amino acid-based hormones exert their effects through intracellular ________.

Glucagon and insulin both target the cells of the liver and are both made in the pancreas, yet they have very different effects on the cells they target. What accounts for this fact?

Growth hormone solely exerts its influence by targeting other endocrine glands to produce hormones.

Steroid hormones exert their action by ________.

Figure 15.1 Using Figure 15.1, match the following: -Produces hormones and is considered a neuroendocrine organ.

Briefly discuss target cell activation by hormone-receptor interaction.

Match the following: A) Hypophysis B) Thyroid C) Adrenal medulla D) Parathyroid E) Pancreas -The gland that controls the fight-or-flight reaction.

Match the following: A) Hypophysis B) Thyroid C) Adrenal medulla D) Parathyroid E) Pancreas -Produces a hormone that controls blood levels of calcium and potassium by their removal from bone tissue.

The single most important regulator of calcium levels in the blood is ________.

Many hormones synthesized in the gastrointestinal tract are chemically identical to brain neurotransmitters.

Leptin is secreted by ________.

Oxytocin ________.

The second-messenger mechanism of hormone action operates by ________.

Match the following: A) Myxedema B) Acromegaly C) Cretinism D) Cushing's disease -Hyposecretion of the thyroid in infants.

What ion is sometimes used as a second messenger of amino acid-based hormones?

The prime metabolic effect of cortisol is gluconeogenesis.

List the four mechanisms involved in the regulation of aldosterone secretion.
