Question

Match List-I with List-II: 
 \[ \begin{array}{|l|l|} \hline \textbf{List-I (Ascending tract of the spinal cord)} & \textbf{List-II (Function)} \\ \hline A. \ \text{Lateral spinothalamic tract} & I. \ \text{Pain and temperature from opposite half of the body} \\ B. \ \text{Anterior spinothalamic tract} & II. \ \text{Vibratory sense} \\ C. \ \text{Fasciculus Cuneatus} & III. \ \text{Crude touch and pressure from opposite half of the body} \\ D. \ \text{Posterior spinocerebellar tract} & IV. \ \text{Unconscious proprioception to cerebellum} \\ \hline \end{array} \]

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

Hint:

The spinothalamic tracts carry pain and temperature, while the posterior spinocerebellar tract carries proprioception.

Answer 1

The Correct Option is D

Step 1: Understanding the spinal cord tracts.
The ascending tracts of the spinal cord transmit sensory information to the brain. These include pathways for pain, temperature, touch, and proprioception.
Step 2: Analyzing each tract and its function.
- (A) Lateral spinothalamic tract: It carries pain and temperature sensation from the opposite half of the body.
- (B) Anterior spinothalamic tract: It transmits crude touch and pressure sensations from the opposite side of the body.
- (C) Fasciculus Cuneatus: It conveys fine touch and vibratory sense from the upper half of the body.
- (D) Posterior spinocerebellar tract: It transmits unconscious proprioception information to the cerebellum.
Step 3: Conclusion.
The correct matching is: (A) - (I), (B) - (II), (C) - (III), (D) - (IV).
