Question

Which one of the following pairs correctly matches a hormone with a disease resulting from its deficiency?

A

Relaxin – Gigantism

B

Prolactin – Cretinism

C

Parathyroid hormone – Tetany

D

Insulin – Diabetes insipidus

Step-by-Step Solution

This question requires integrating knowledge from two different units of the Class 11 Biology curriculum: Locomotion and Movement and Chemical Coordination and Integration. According to the sources, tetany is a disorder characterised by rapid muscle spasms caused by low Ca2+ levels in body fluids . The parathyroid hormone (PTH) acts as a hypercalcemic hormone that increases blood Ca2+ levels . Consequently, a deficiency in PTH leads to hypocalcemia, which results in tetany . Other options are incorrect: gigantism results from excess Growth Hormone , cretinism results from thyroid hormone deficiency during pregnancy , and diabetes insipidus is caused by a deficiency of ADH (vasopressin) . Mastering these NCERT-based clinical associations is essential as approximately 95% of NEET Biology questions are derived directly from these primary textbooks .

Exam Context & Concepts Covered

This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Chemical Coordination and Integration. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): FSH which interacts with membrane bound receptors does not enter the target cell. Reason (R): Binding of FSH to its receptors generates second messenger (cyclic AMP) for its biochemical and physiological responses. In the light of the above statements, choose the most appropriate answer from the options given below:

A.Both (A) and (R) are True and (R) is the correct explanation of (A).
B.Both (A) and (R) are True but (R) is not the correct explanation of (A).
