Eicosanoid hormones

Paracrines -are secreted into the blood stream -are secreted into a duct -act on the neighboring cell -act on the cell that secreted them

act on the neighboring cell

Which of the following anterior pituitary hormones stimulates the adrenal cortex to secrete cortisol? -Luteinizing hormone -Prolactin -Insulin-like growth factors -Melanocyte-stimulating hormone -Adrenocorticotropic hormone

adrenocorticotropic hormone

The responsiveness of a target cell to a hormone is determined by: -The concentration of the hormone in the blood -The number of hormone receptors on the target cell -Influences exerted by other hormones -All of these determine the responsiveness of a target

all of these determine the responsiveness of a target

Which of the following glands are not exclusively classified as endocrine glands but contain hormone secreting cells? -Hypothalamus -Pancreas -Ovaries -Kidneys -All of these glands are correct.

all of these glands are correct

Which of the following can influence the responsiveness of a target cell to a hormone? -The number of receptors on the target cell -The presence and effects of other hormones -The concentration of the hormone -Previous exposure to a hormone -All of the above

all the above

Which of the following is an example of a hormone that is secreted from an endocrine gland in response to a chemical change in the blood? -Parathyroid hormone release from the parathyroid gland. -Insulin release from the pancreas. -Glucagon release from the pancreas. -ADH release from the posterior pituitary gland. -All the answer selections are correct.

all the answer selections are correct

When one hormone opposes the action of another hormone, it is called a(n) -synergistic effect. -permissive effect. -antagonistic effect. -circulating effect. -local effect

antagonistic effect

Which of the following statements correctly compares water-soluble hormones with lipid-soluble hormones? -Both types of hormones are carried in the blood attached to a carrier protein. -Both types of hormone almost always stimulate increases in mRNA transcription. -Only water-soluble hormones use second messengers. -Only water-soluble hormones require a receptor. -Lipid-soluble hormones are not found in the bloodstream.

both types of hormone almost always stimulate increases in mRNA transcription

Releasing hormones from the hypothalamus are carried to the anterior pituitary -via the infundibulum -by axonal transport in the hypothalamohypophyseal tract -by the hypophyseal portal vein -in the systemic circulation

by the hypophyseal portal vein

Since insulin released from the pancreas is carried in the bloodstream to distant target cells, like muscle cells, it is considered to be a(n) -local hormone. -circulating hormone. -paracrine. -autocrine. -neurotransmitter.

circulating hormone

ACTH causes the release of -aldosterone -cortisol -calcitonin -calcitriol -aldosterone and cortisol

cortisol

When a hormone is present in excessive levels, the number of target-cell receptors may decrease. This is called -receptor recognition. -sensory adaptation. -paracrine regulation. -up-regulation. -down-regulation.

down regulation

Which hormone is not matched correctly with its principal action? gastrin - increases stomach movement erythropoietin (EPO) - increases white blood cell production leptin - suppresses appetite atrial natriuretic peptide (ANP) - lowers blood pressure estrogens - prepare mammary gland to secrete milk

erythropoietin (EPO)- increases white blood cell production

false

Most water soluble hormones must be attached to a transport protein in order to be circulated true or false

false

norepinephrine

How are most hormones released? -On a continuous, low-level basis -In short bursts with little or no secretion between bursts. -In a gradually increasing then decreasing pattern -Continuously at high levels -It depends on the immediate needs of the body

on a continuous, low level basis
