Question

Match the LIST-I (Biomedical Signals) with LIST-II (Source): 
\[ \begin{array}{|l|l|} \hline \textbf{LIST I (Biomedical Signals)} & \textbf{LIST II (Source)} \\ \hline A. \ \text{Electromyogram} & I. \ \text{Pulmonary System} \\ B. \ \text{Blood pressure} & II. \ \text{Ocular System} \\ C. \ \text{Respiratory Parameters} & III. \ \text{Muscular System} \\ D. \ \text{Electroculogram} & IV. \ \text{Cardiovascular System} \\ \hline \end{array} \]
Choose the correct answer from the options given below: 
 

• A. A - II, B - III, C - IV, D - I
• B. A - III, B - I, C - II, D - IV
• C. A - III, B - IV, C - I, D - II
• D. A - III, B - II, C - I, D - IV

Hint:

Electro- = recording signal. EMG → muscle, ECG → heart, EEG → brain, EOG → eye.

Answer 1

The Correct Option is C

Step 1: Recall biomedical signals and their origins.
- Electromyogram measures muscle electrical activity → Muscular System.
- Blood pressure is a measure of cardiac output and vascular resistance → Cardiovascular System.
- Respiratory parameters such as tidal volume and rate are linked to → Pulmonary System.
- Electroculogram records eye movements by detecting potential differences → Ocular System.
Step 2: Match correctly.
A → III, B → IV, C → I, D → II.
Step 3: Verify options.
Option (C) matches all associations correctly.
Step 4: Conclusion.
Hence, Electromyogram - Muscular System, Blood Pressure - Cardiovascular, Respiratory Parameters - Pulmonary, Electroculogram - Ocular.
