(BIOL 2302) Exam 1 Review Questions | 2026/2027 |
Answers Correct | With Complete Solutions
Acinar Cells Correct Answers exocrine cells that produce
enzyme-rich juice for digestion
Acromegaly Correct Answers caused by hypersecretion of GH
in adults
Addison's Disease Correct Answers caused by the hypo
secretion of glucocorticoids
Adiponectin Correct Answers enhances sensitivity to insulin
Adrenocorticotropic Hormone/Corticotropin (ACTH) Correct
Answers -stimulus: corticotropin-releasing hormone (CRH)
-target: adrenal cortex
-effect: stimulates the release of glucocorticoids and androgens
Adrenogenital Syndrom Correct Answers caused by the hyper
secretion of gonadocorticoids in women
Aldosterone Correct Answers -the most potent
mineralocorticoid
-Release triggered by decreasing blood volume and blood
pressure or rising blood levels of K+
Aldosteronism Correct Answers -hypersecretion due to adrenal
tumors
-Hypertension and edema due to excessive Na+
,-Excretion of K+ leading to abnormal function of neurons and
muscle
Antagonism Correct Answers one or more hormones oppose(s)
action of another hormone
Anterior Pituitary Lobe Correct Answers -Originates as
outpocketing of oral mucosa
-Vascular connection to hypothalamus
Antidiuretic Hormone (ADH)/Vasopressin Correct Answers -
stimulus: impulses from hypothalamic neurons in response to
increases blood solute concentration or decreases blood volume
-target: kidneys
-effects: stimulates kidneys to reabsorb more water, reducing
urine output
Autocrines Correct Answers chemicals that exert effects on
same cells that secrete them
Calcitonin Correct Answers -stimulus: high levels of calcium
in blood
-target: bones
-effects: N/A
Catecholamines: Epinephrine and Norepinephrine Correct
Answers -stimulus: impulses from preganglionic sympathetic
fibers
-target: most body cells
-effects: "fight-or-flight response"
, Cholecalciferol Correct Answers precursor of vitamin D
Cholecystokinin Correct Answers stimulates pancreas,
gallbladder, and hepatopancreatic sphincter
Classes of Hormones Correct Answers -Amino acid-based
hormones
-Steroids
Cortisol Correct Answers -Released in response to ACTH,
patterns of eating and activity, and stress
-Prime metabolic effect is gluconeogenesis
-Promotes rises in blood glucose, fatty acids, and amino acids
-"Saves" glucose for brain
-Enhances vasoconstriction
Cretinism Correct Answers caused by hyposecretion of thyroid
hormone in infants
Cushing's Syndrome/Disease Correct Answers caused by the
hyper secretion of glucocorticoids
Diabetes Insipidus Correct Answers -ADH deficiency due to
hypothalamus or posterior pituitary damage
-Must keep well-hydrated
Down-Regulation Correct Answers target cells lose receptors
in response to high hormone levels
Effects of Insulin Correct Answers -Lowers blood glucose
levels
