CHAPTER 11 ENDOCRINE TEST BANK
LATEST UPDATE!
QUESTIONS AND ANSWERS
Label structures of pancreas and nearby structures:. ANSWER - Left: Gallbladder, small
intestine
Right: Bile duct, pancreatic duct, pancreas
Which of the following hormones is released when blood glucose levels are elevated?.
ANSWER - insulin
Complete table to compare nervous system and endocrine system:. ANSWER - Cells:
neurons, epithelial and others
Chemical signal: neurotransmitters, hormones
Specificity of action: receptors on postsynaptic cell, receptors on target cells
Speed of onset: seconds, seconds to hours
Duration of action: very brief unless neuronal activity continues, may be brief or may last
days even if secretion ceases
Match pituitary hormone with its function. ANSWER - Causes kidneys to retain water,
raises BP: ADH
Promotes secretion of sex hormones from gonads: LH
Stimulates egg or sperm production: FSH
, Stimulates release of hormones from adrenal cortex: ACTH
Stimulates secretion of thyroid hormones: TSH
Stimulates production of milk: PRL
Stimulates rate of mitosis, promotes bone growth: GH
Stimulates contraction of uterine wall muscles, stimulates smooth muscle in milk-secreting
glands: OT
Arrange negative feedback loop for blood glucose regulation:. ANSWER - Too high - up,
around, down: Stimulus (rise in blood glucose), Receptor (Beta cells detect rise), Control
Center (Beta cells secrete insulin), Effectors (insulin), Response (blood glucose drops to
normal)
Too low - down, around, up: Stimulus (drop in glucose), Receptor (Alpha cells detect drop),
Control Center (Alpha cells secrete glucagon), Effectors (glucagon), Response (blood
glucose rises to normal)
Label to indicate whether secretion is endocrine or exocrine. ANSWER - Endocrine:
Secretions distributed through bloodstream.
Secretions serve as form of cell to cell communication.
Secretions belong to three chemical categories; steroids, monoamines, peptides.
Glands exhibit high density of capillaries.
Exocrine:
Secretions are released via ducts onto epithelial tissues.
Secretions might serve to lubricate mucosal membranes.
Secretions might contain metabolic wastes and antimicrobial substances.
