All the unconscious activities like heartbeat, involuntary beathing and gut period are controlled by:
Correct answer: A. Medulla oblongata
- A. Medulla oblongata
- B. Cerebrum and medulla
- C. Cerebellum and medulla
- D. Cerebrum and cerebellum
Explanation
All the unconscious activities like heartbeat, involuntary breathing, and gut peristalsis are primarily controlled by the "autonomic nervous system." The autonomic nervous system (ANS) is a division of the peripheral nervous system that regulates involuntary physiological processes essential for maintaining bodily functions and homeostasis.These unconscious activities are regulated by complex neural pathways and feedback loops involving the brain, spinal cord and medulla oblongata. The autonomic nervous system continuously monitors and adjusts these processes to respond to changes in the body's needs and external conditions.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
