The composition of the white matter of the spinal cord is:
Correct answer: D. Myelinated axon
- A. Myelinated dendrite
- B. Non-myelinated dendrite
- C. Non-myelinated axon
- D. Myelinated axon

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.
