Question

LaKeisha stepped on a piece of glass and quickly pulled her foot away from that sharp object. Which of the following are responsible for sending a message to the muscles in LaKeisha's foot, resulting in her pulling her foot away from the piece of glass?

a. motor neuronsb. interneuronsc. sensory neuronsd. reflexese. spinal neurons

Answer 1

Motor neurons.

Step-by-step explanation:

Neurons may be defined as the structural and functional unit of the nervous system. Three main types of neuron are inter neuron, sensory neuron and motor neuron.

The motor neuron carry the nerve impulse from the brain and spinal cord to the effector organs. The muscle has been sent from the central nervous system to the leg (effector organ), so motor neuron has been used for the transmission of nerve impulse into the leg.

Thus, the correct answer is option (a).
