Which part of the human brain coordinates voluntary muscle movements, posture, and balance?
Answer and explanation
Correct answer: B. Cerebellum
- Step 1: The cerebellum (little brain) receives sensory input from proprioceptors, vestibular organs, and motor cortex. Step 2. It fine-tunes motor output, ensuring smooth voluntary muscle coordination, equilibrium, and precision posture. Answer: Cerebellum. Why not the others: Cerebrum handles conscious thought, memory, and sensory perception; Medulla controls vital autonomic reflexes (respiration, cardiac rate); Hypothalamus governs homeostasis.
