KCET · BIOLOGY · STD 11 - 18. Neural Control and Coordination

Hypothalamus of the brain is not involved in this function.

A Sleep-wake cycle
B Osmoregulation and thirst
C Temperature control
D Accuracy of muscular movement

Verified Solution

Answer & Solution

Correct Answer

(D) Accuracy of muscular movement

Step-by-step Solution

Detailed explanation

(D) Accuracy of muscular movement,
The hypothalamus regulates functions like the sleep-wake cycle, osmoregulation, thirst, and temperature control, all of which are crucial for maintaining homeostasis. However, the accuracy of muscular movement is controlled by the cerebellum, which coordinates voluntary movements, posture, and balance.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
