Biology Practice: Endocrine System (Mock Test 4 - Expert: Experimental Logic & Clinical Data)
1. In a laboratory experiment, a rat's thyroid gland was removed. Which of the following physiological changes would be logically observed?
2. A patient presents with "Diabetes Insipidus". Clinical tests show that their pancreas is producing normal levels of insulin. The logical cause is:
3. Expert Analysis: Why is Adrenaline called an 'Emergency Hormone' regarding its effect on the Liver?
4. If a person's diet is severely deficient in Iodine, why does the Thyroid gland enlarge (Simple Goitre)?
5. Clinical Data: A patient shows "Moon Face", obesity in the trunk, and high blood pressure. This is logically diagnosed as:
6. If the Islets of Langerhans are surgically removed from a test animal, which chemical change will occur in the blood?
7. Why do doctors prescribe "Insulin Injections" rather than oral pills for diabetic patients?
8. Data Interpretation: A person has very low blood pressure, loss of energy, and skin pigmentation. This indicates "Addison's Disease" due to:
9. Which of the following is an experimental proof of the "Master" status of the Pituitary gland?
10. Logical Inference: Why does a "Cretin" (child with hypothyroid) show stunted mental growth alongside physical stunting?
11. A sudden rise in TSH levels in the blood is a logical signal that:
12. Clinical Symptom: "Bulging Eyes" (Exophthalmos). This is logically caused by:
13. Why is the "Post-Anterior Pituitary" (Posterior Lobe) technically not a true endocrine gland?
14. What happens logically if a person's Adrenal Medulla is removed?
15. Data: A patient has "Acromegaly". This indicates hypersecretion of GH during:
16. Why does "Glycosuria" (glucose in urine) occur in Diabetes Mellitus?
17. Logical connection: Hyposecretion of ADH $\rightarrow$ Large volume of dilute urine. This condition is:
18. If "Alpha cells" of the Pancreas are destroyed, the person will struggle to:
19. "Hormones are target-specific". This implies that:
20. What is the logical purpose of the "Islets of Langerhans" having a rich blood supply?
