Correct answer: A. Sensory neuron
- A. Sensory neuron
- B. Motor neuron
- C. Efferent neuron
- D. Interneuron
- E. Ganglion

A sensory neuron is a nerve cell that detects and responds to external signals via receptors and converts this information into electrical impulses. These electrical responses are then transmitted to interneurons via sensory neurons, where information is processed and signals are sent to the effectors through motor neurons.

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.
