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 eventschronologically.

1. receoptors in her toe receive stimuli

2.her sensory neurone generates an impulse.

3. interneurones relay the impulse to motor neurons in spinal cord.

4. motor neurone signal the leg muscles

5. she immediately moves her foot

Explanation:

A kind of nerve circuit that results in the generation of a reflex is known as the reflex arc. The information that originates from the surroundings is captivated by the sensory receptors, which converts the information to a nerve message and transmit it towards the central nervous system, which interprets it and produces a response.  

In the given case, the reaction is generated in the following manner:  

a. The receptors present in the toe attains stimuli.  

b. An impulse is generated by the sensory neurons.  

c. The impulse is relayed to the motor neurons in the spinal cord by the interneurons.  

d. The leg muscles receive the signals by the motor neurons.  

e. The foot gets moved instantaneously.
