HUBS191: Endocrine System Exam Questions With
Complete Solutions
____ cells secrete insulin, while _____ cells secrete glucagon.
Correct Answers Beta, alpha
Adrenaline is a ___________-type hormone and travels via
______. Correct Answers Catecholamine, blood
Another name for growth hormone Correct Answers
Somatotropin
Another name for the anterior pituitary gland Correct Answers
Adenohypothesis
Another name for the posterior pituitary gland Correct Answers
Neurohypothesis
Anti-diuretic hormone is also known as? Correct Answers
Vasopressin
Because adrenaline is a _____-soluble hormone it binds to a ___
________ receptor. Correct Answers Water, cell membrane
Can lipid proteins be stored? How do they travel? Correct
Answers No, they cannot be bound by a membrane as they
would simply diffuse across it. They travel bound to carrier
proteins. (Exception: Thyroid hormone has a storage form)
Can peptide hormones be stored? How do they travel? Correct
Answers Yes. They travel dissolved in the blood.
, Compare and contrast neuronal and hormonal responses.
Correct Answers Neuronal: APs travel down axons and release
NT at discrete synapses. Targeting is achieved by specific
"wiring" and transmission speed is very fast. Brief and rapid
responses.
Hormonal: Hormones released into blood. Targeting is achieved
by expression of specific receptors on target cells. One hormone
can have many targets cells. Relatively slow, but action is long-
lasting, widespread and sustained.
Corticotropin-releasing hormone stimulates the anterior pituitary
gland to produce what hormone? Correct Answers
Adrenocorticotropic hormone
Cortisol binds to a receptor located where? Correct Answers
The cytoplasm
Cortisol is a ______ hormone and so travels via a ________
________. Correct Answers Steroid, carrier protein
Dopamine is also known as what? Correct Answers Prolactin
inhibiting hormone (PIH)
Effect of calcitonin Correct Answers ↓ bone breakdown
↓ release of Ca2+ into the blood
Effects of glucagon Correct Answers ↑ glycogenolysis
(glycogen breakdown)
↑ glucose/ketone synthesis
↑ blood glucose concentration
