There is no clear difference between dendrites and axons in sensory neurons, except:
Correct answer: C. Terminal portions
- A. Thickness
- B. Length
- C. Terminal portions
- D. None of the above
Explanation
The main difference between dendrites and axons lies in their terminal portions. Dendrites have numerous branches at their terminals, which receive signals from other neurons and transmit them towards the cell body. Axons, on the other hand, have a single branch called the axon terminal, which transmits signals away from the cell body to other neurons or effector cells.

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.
