Question

Do ventral roots of spinal nerves contain sensory or motor neurons?

1) Sensory neurons
2) Motor neurons

Answer 1

Ventral roots of spinal nerves contain motor neurons, which are responsible for transmitting motor impulses from the spinal cord to muscles, facilitating movement.

Step-by-step explanation:

The ventral roots of spinal nerves contain motor neurons. In the human nervous system, each spinal nerve is composed of both sensory and motor axons. The sensory neuron cell bodies are located in the dorsal root ganglia and enter the spinal cord via the dorsal nerve root. In contrast, motor neurons have their cell bodies in the ventral gray matter of the spinal cord. These motor neurons project to muscles using the ventral root. Therefore, the ventral roots are associated with the transmission of motor impulses from the spinal cord to various muscles, enabling movement and voluntary muscle control.
