The term that should be last in the reflex sequence is:
Correct answer: B. Effector
- A. Receptor
- B. Effector
- C. Sensory neuron
- D. Motor neuron
Explanation
Impulse first is received from the receptive, after which it is carried on by the sensory neuron, which then goes towards the interneuron and then the motor neuron in the spinal cord. The motor neuron carries the impulse towards the effector, and the reflex action is completed.

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.
