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: Comprehending spinal cord tracts.
Ascending spinal cord tracts convey sensory data to the brain, encompassing pathways for pain, temperature, touch, and proprioception.
Step 2: Examining tracts and their roles.
- (A) Lateral spinothalamic tract: Transmits pain and temperature sensation from the contralateral body half.
- (B) Anterior spinothalamic tract: Relays crude touch and pressure sensations from the contralateral body side.
- (C) Fasciculus Cuneatus: Carries fine touch and vibratory sense from the superior body half.
- (D) Posterior spinocerebellar tract: Delivers unconscious proprioception data to the cerebellum.
Step 3: Determination.
The accurate correspondences are: (A) - (I), (B) - (II), (C) - (III), (D) - (IV).
