The dendrites of a typical vertebrate motor neuron, compared to the neuron's axon are generally?
Correct answer: D. More branched
- A. Longer
- B. More myelinated
- C. Larger in diameter
- D. More branched
Explanation
The dendrites of a typical vertebrate motor neuron, compared to the neuron's axon, are generally more branched. Dendrites are the extensions of a neuron that receive signals from other neurons and transmit those signals toward the cell body. They have a tree-like structure with numerous branches, which allows them to receive input from multiple sources.

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.
