Reflex actions below the neck are under control of:
Correct answer: C. Spinal cord
- A. Brain
- B. Hypothalamus
- C. Spinal cord
- D. Pituitary gland
Explanation
Reflex actions below the neck are primarily under the control of the "spinal cord". The spinal cord plays a crucial role in processing and coordinating reflex responses that do not require input from the brain. These reflexes, known as spinal reflexes, involve the sensory input from peripheral nerves that are transmitted to the spinal cord, where motor commands are generated and executed without conscious thought or involvement from the brain.

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.
