Question

Match List I with List II related to muscular/skeletal system:

| List I | | List II | |
|---|---|---|---|
| A. | Tetany | I. | Inflammation of joints |
| B. | Arthritis | II. | Autoimmune disorder affecting neuromuscular junction |
| C. | Myasthenia gravis | III. | Wild contraction in muscle due to low $Ca^{++}$ in body fluid |
| D. | Muscular dystrophy | IV. | Progressive degeneration of skeletal muscle |

Choose the correct answer from the options given below:

Accepted Answer

A. 1. **Recall what each disorder means.**

**Tetany** is a condition of rapid, wild muscle spasms caused by **low $Ca^{++}$ levels** in body fluids.

**Arthritis** refers to **inflammation of the joints**.

**Myasthenia gravis** is an **autoimmune disorder** that affects the **neuromuscular junction**, leading to weakness and fatigue of skeletal muscle.

**Muscular dystrophy** is a genetic disorder causing **progressive degeneration of skeletal muscle**.

2. **Match each term to its definition.**

So, **A (Tetany) → III**, **B (Arthritis) → I**, **C (Myasthenia gravis) → II**, **D (Muscular dystrophy) → IV**.

Hence, the answer is **Option A (A-III, B-I, C-II, D-IV)**.

List I		List II
A.	Tetany	I.	Inflammation of joints
B.	Arthritis	II.	Autoimmune disorder affecting neuromuscular junction
C.	Myasthenia gravis	III.	Wild contraction in muscle due to low $Ca^{++}$ in body fluid
D.	Muscular dystrophy	IV.	Progressive degeneration of skeletal muscle
