Answer:
Motor nerves
Explanation:
Pulling the leg quickly from the sharp object is an example of reflex action. It includes sensory receptors, sensory neurons, interneurons, the control center (spinal cord), motor neurons and effector.
As soon as she steps on the glass piece, the receptors present in the skin of her foot sole sense it and send the information to the control center via sensory neurons. The spinal cord commands the muscles of the effector organ (leg) via motor neurons to move to step away from the glass piece.
The motor neurons are responsible for sending a message to the muscles in foot resulting in movement of the foot.
What are motor nerves?
They are the nerve cells, which are accountable for transmitting signals away from the central nervous system towards the muscles to conduct movement. They discharge neurotransmitters, which provoke reactions resulting in the movement of muscle.
One of the illustration of the reflex action is the pulling of the leg quickly from the sharp object. It comprises the activity of sensory neurons, sensory receptors, motor neurons, the spinal cord, and the effector. When one step on the sharp object, the receptors present in the skin of the foot sense it and transmit the signal to the spinal cord with the assistance of sensory neurons.
The spinal cord further instructs the muscles of the leg or the effector through the motor neurons to step away from the sharp object.
Thus, the correct answer is motor nerves.
