The reflex action is the phenomena which only involves:
Correct answer: C. Receptors, effectors and spinal cord
- A. Brain. receptors, spinal cord
- B. Receptors, neurons, brain
- C. Receptors, effectors and spinal cord
- D. Receptors and effectors
Explanation
The simplest arrangement of a reflex are consists of the receptors, an interneuron, and an effector; together these units from a finctional reflex group. Brain is, however, excluded in the reflex arc.

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.
