This diagram shows how the body keeps blood glucose at a normal level.

A: Pancreas releases insulin B: Body cells takes up more glucose C: Liver takes up glucose and stores it as glycogen D: Blood glucose decreases to normal E: Pancreas releases glucagon F: Liver breaks down glycogen and releases glucose to the blood G: Blood glucose returns to normal

The images show the events that occur in your body after you eat a sugary snack. Put the events in the correct sequence

blood glucose becomes high-->pancreas releases insulin-->insulin binds to receptors on target cells-->cells take in glucose-->blood glucose returns to normal

cells of the body

choose which condition, has all of the following symptoms: hypertension, hyperglycemia, "moon face"

cushing's disease

Which of the following adrenal gland homeostatic imbalances is characterized by persistent elevated blood glucose levels, dramatic losses in muscle and bone protein, and water and salt retention, leading to hypertension and edema?

cushing's syndrome

Which of the following triggers the release of glucagon?

decrease in blood glucose levels

in response to stress, which of the following changes would happen?

decreased insulin secretion

Which of the following is NOT a major type of stimulus that triggers endocrine glands to manufacture and release hormones?

epinephrine

Steroid hormones are synthesized from amino acids.

false

The benefit of using a second messenger signaling system is rapid speed of communication.

false

Up-regulation involves the loss of receptors and prevents the target cells from overreacting to persistently high hormone levels.

false

Water-soluble hormones are metabolized quickly by the liver.

false

The hypothalamus is known to control the activity of the thyroid, which has traditionally been called the master endocrine gland.

false (pituitary gland)

Which of the following hormones has a different effect when it is released in males instead of females?

follicle-stimulating hormone

What is required for the production of anterior pituitary gland hormones?

hormonal stimuli

What type of stimulation controls parathyroid release?

humoral

Where is thyrotropin-releasing hormone (TRH) made?

hypothalamus

Which of the following brain structures would cause central diabetes insipidus if it were damaged?

hypothalamus

One can predict that a person suffering from diabetes mellitus would probably have ______.

increased secretion of ADH (anti-diuretic hormone)

Variance in which of the following hormones is responsible for diabetes mellitus (DM)?

insulin

Which of the following best describes the hypoglycemic effect of insulin?

insulin allows entry of glucose into most body cells

Which of the following exhibits an antagonistic relationship?

insulin/glucagon

Which of the following is NOT characteristic of water-soluble hormones?

intracellular receptors

What material is stored in the thyroid follicles?

iodinated thyroglobulin, from which thyroid hormone can be released

less calcium is placed in the urine by the kidneys

What property of a hormone would allow it to pass unassisted through a plasma membrane?

lipid-soluble

What happens in the body when blood glucose levels fall? The diagram shows the steps in the homeostasis pathway that occur when blood glucose levels fall.
