,Version Module 6.1
1. Does The Nervous System Or The Endocrine System React Faster To
External/Internal Stimuli?
ANS. Nervous System.
Explanation: The Nervous System Uses Rapid Electrical Signals, Allowing Faster
Responses Than The Endocrine System.
2. What Are 2 Major Groups Of Hormones And What Are Their Derivatives?
ANS.
Peptide (Derived From Proteins And Catecholamines)
Steroids (Derived From Cholesterol)
Explanation: Peptide Hormones Are Amino Acid-Based; Steroid Hormones Are Lipid-
Based And Derived From Cholesterol.
3. Hormones Can React With Cells That Have What On Their Cell Surface?
A. Enzymes
B. Receptors
C. Mitochondria
D. Ribosomes
ANS. B.
Explanation: Hormones Act Only On Target Cells Possessing Specific Receptors.
4. Do Peptide Or Steroid Hormones React Faster?
A. Steroid Hormones
B. Peptide Hormones
C. Both React Equally
D. Neither Reacts Quickly
,ANS. B.
Explanation: Peptide Hormones Act Through Cell Membrane Receptors And Second
Messengers, Making Responses Faster.
5. True Or False
Endocrine Glands Contain Ducts And Secrete Their Contents Directly Into An
Epithelial Lining.
A. True
B. False
ANS. B.
Explanation: Endocrine Glands Are Ductless, Secreting Their Contents Directly Into
The Bloodstream.
6. True Or False
The Hypothalamus And Pituitary Glands Are In The Abdomen.
A. True
B. False
ANS. B.
Explanation: They Are Located In The Brain.
7. What Major Hormones Are Secreted From The Anterior Pituitary Gland?
ANS.
Growth Hormone (GH)
Prolactin (PRL)
Melanocyte Stimulating Hormone (MSH)
Thyroid Stimulating Hormone (TSH)
Adrenocorticotropic Hormone (ACTH)
Follicle Stimulating Hormone (FSH)
Luteinizing Hormone (LH)
,Explanation: These Hormones Regulate Growth, Metabolism, Reproduction, And Stress
Response.
8. What Major Hormones Are Secreted From The Posterior Pituitary Gland?
ANS.
Oxytocin (OXT)
Antidiuretic Hormone (ADH)
Explanation: Posterior Pituitary Stores And Releases These Hormones Produced By The
Hypothalamus.
9. The Adrenal Glands Are Found On Top Of The _____________.
A. Liver
B. Kidneys
C. Pancreas
D. Spleen
ANS. B.
Explanation: Adrenal Glands Sit Superior To Each Kidney.
10. Name 3 Secondary Endocrine Organs.
ANS. Heart, Thymus, Kidneys, Gonads (Testes & Ovaries)
Explanation: These Organs Have Additional Endocrine Functions.
,11. Describe Homeostasis In The Body.
ANS.
(Set-Point) Is A Range In Which The Body Acts To Maintain All Its Levels For
Function.
Explanation: Homeostasis Keeps Internal Conditions Stable.
12. During Negative Feedback A Hormone Level Is High. What Happens To
Hormone Production?
ANS.
The Brain Detects The Hormone Level Is Too High And Hormone Production Is Shut
Off.
Explanation: Negative Feedback Reduces Hormone Output To Restore Balance.
13. The Action Of Oxytocin (OXT) Works Through Positive Or Negative Feedback?
A. Positive Feedback
B. Negative Feedback
C. Both
D. Neither
ANS. A.
Explanation: Oxytocin Amplifies Responses Such As Labor Contractions.
14. Why Are The Neurons In The Hypothalamus Called Neurosecretory Cells?
ANS.
They Are Cells That Respond To Neurotransmitters And Produce Hormones.
Explanation: They Function As Both Neurons And Endocrine Cells.
15. Axons Travel From The Hypothalamus Terminate In What Region Of The
Brain?
A. Cerebellum
B. Posterior Pituitary
, C. Medulla
D. Frontal Lobe
ANS. B.
Explanation: Hypothalamic Axons Terminate In The Posterior Pituitary.
16. The Posterior Pituitary Gland Stores What 2 Main Hormones?
ANS.
ADH And OXT (Antidiuretic Hormone And Oxytocin)
Explanation: These Are Released From The Posterior Pituitary.
17. What Does ADH Do In The Body?
ANS.
ADH Promotes The Reabsorption Of Water From The Collecting Ducts, Which Receive
Urine Produced By Nephrons Within The Kidneys.
As The Blood Becomes Dilute, The Hormone No Longer Is Released Until It Is Needed
Again.
Explanation: ADH Regulates Water Balance And Blood Osmolarity.
18.What Hormone Stimulates The Release Of Milk From The Mammary Glands?
A. Prolactin
B. Oxytocin
C. Growth Hormone
D. ADH
ANS. B.
Explanation: Oxytocin Causes Milk Ejection; Prolactin Stimulates Milk Production.
19. What Are The Primary Endocrine Organs?
ANS.
Hypothalamus
Pituitary Glands
Pineal Gland
