Correct answer: B. Receptors to CNS
- A. Effector organs to CNS
- B. Receptors to CNS
- C. CNS to receptors
- D. CNS to muscles

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.
