Drag each tile to the correct box.

Lucia is walking barefoot in her yard. She accidentally steps on a nail. How will her nervous system work to generate a reaction? Arrange the events chronologically.

Interneurons relay the impulse to motor neurons in the spinal cord.

She immediately moves her foot.

The sensory neuron generates an impulse.

Receptors in her toe receive stimuli.

Motor neurons signal the leg muscles.

The sensory neuron generates an impulse.

Inter neurons relay the impulse to motor neurons in the spinal cord.

Motor neurons signal the leg muscles.

Receptors in her toe receive stimuli.

She immediately moves her foot.

I believe that would be the correct order if i am wrong i do apologize

Correct order is

a) Receptors in her toe receive stimuli.

b) The sensory neuron generates an impulse.

c) Inter neurons relay the impulse to motor neurons in the spinal cord.

d) Motor neurons signal the leg muscles.

e) She immediately moves her foot.

Explanation:

Foot of Lucia contains stimuli receptors. As Lucia steps on the nail, the receptors in the toe receives the stimuli and hence her sensory neurons becomes active and they generate an impulse. These impulses are transmitted from sensory neurons via inter neurons to the brain. Brain processes the information and sends the message via inter neurons to the motor neurons. Motor neurons then signals the leg muscles and then she immediately removes her leg away from the pin.

Hence correct order is

a) Receptors in her toe receive stimuli.

b) The sensory neuron generates an impulse.

c) Inter neurons relay the impulse to motor neurons in the spinal cord.

d) Motor neurons signal the leg muscles.

e) She immediately moves her foot.
