Question

Match the structures of the brain in the first column with their respective functions in the second column.

Brain Structures	Functions
P) Cerebellum	iii) Controls fine motor skills
Q) Thalamus	iv) Relays and filters information from the senses and transmits the information to the cerebral cortex
R) Tectum	i) Orients a person in the environment
S) Medulla	ii) Coordinates heart rate, circulation, and respiration

• A. P-(iii), Q-(i), R-(iv), S-(ii)
• B. P-(i), Q-(iv), R-(ii), S-(iii)
• C. P-(iv), Q-(iii), R-(ii), S-(i)
• D. P-(iii), Q-(iv), R-(i), S-(ii)

Hint:

Remember: \textbf{Cerebellum} = coordination, \textbf{Thalamus} = sensory relay, \textbf{Tectum} = orienting, \textbf{Medulla} = vital autonomic functions.

Answer 1

The Correct Option is D

Step 1: Recall key functions.
Cerebellum \(\Rightarrow\) coordination/fine motor control \(\Rightarrow\) (iii).
Thalamus \(\Rightarrow\) sensory relay to cortex \(\Rightarrow\) (iv).
Tectum (superior/inferior colliculi) \(\Rightarrow\) orienting reflexes to sights/sounds \(\Rightarrow\) (i).
Medulla \(\Rightarrow\) autonomic control of heart rate, circulation, respiration \(\Rightarrow\) (ii).

Step 2: Map and choose.
Thus \(P\!\to\!(iii),~Q\!\to\!(iv),~R\!\to\!(i),~S\!\to\!(ii)\), which matches option (D).
Final Answer: (D)
