The ventral root of the spinal cord contains axons of:
Correct answer: B. Motor neuron
- A. Sensory neuron
- B. Motor neuron
- C. Mixed neuron
- D. Spinal neuron
Explanation
The ventral root of the spinal cord contains the axons of motor neurons. Motor neurons are responsible for carrying signals from the central nervous system (CNS), specifically the spinal cord, to the muscles and glands in the body. These axons form the efferent pathway, transmitting signals that control voluntary and involuntary muscle contractions, as well as other motor functions. When the motor neurons in the ventral horn of the spinal cord are activated, their axons exit the spinal cord through the ventral root and connect with the appropriate muscles or glands, enabling movement and other motor responses.

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.
