Correct answer: B. Different receptors are present for detection of stimuli
- A. For each sensation, different form of nerve impulse is generated
- B. Different receptors are present for detection of stimuli
- C. All nerves send their impulse to same part of brain
- D. Each stimulus acts on different parts of body

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.
