Motor Neuron

Describe the reflex arc!

Neuron Review #31. Rubber hammer makes

contact with skin of lower knee

2. The skin’s sensory neuron sends an impulse to the spinal cord

3. Inside the spinal cord is the interneuron, which will transport the signal to the motor neuron

4. The motor neuron will send the impulse signal to muscle. The muscle will contract and release.

5. The entire leg will now go through a “kicking” motion, this is the response to the initial stimulus that occurred in step #1

Neuron Review #4Which part of the neuron is known to receive

a stimulus and start a impulse in a neuron cell? #1

Review Question #10What happens to the impulse once it reaches

the end of the neuron?The end of the electrical impulse signals chemical messengers to be released (neurotransmitters) so they can stimulate the next electrical impulse in neighboring neuron

1. Name that neurotransmitter…It’s late, and you are in a dark alley and hear

heavy footsteps behind you. Your neurons diffuse a neurotransmitter that helps your body resist or avoid stress, fight or flight response.

MelatoninEndorphinEpinephrineSerotoninDopamine

Epinephrine

2. Name that neurotransmitter…Teenagers produce this neurotransmitter later at

night (compared to adults and children) and it is still produced in the morning. Some people believe this effects teens learning in school. High schools have debated starting school later for this reason.


Melatonin

3. Name that neurotransmitter…People with depression have lower

concentrations of this neurotransmitter. They have difficulty feeling pleasure and pain.


Dopamine

4. Name that neurotransmitter…When Ms. O’Connor was in college she was required

to run 12 miles with her teammates at 9am every single Sunday!

It was a miserable run for Ms. O’Connor the first 8 miles, but the last 4 miles seemed to be painless and calming to her. She knew she could make it all the way. What neurotransmitter was she releasing?


Endorphin

5. Name that neurotransmitter…Mary Jane is struggling with school and life lately,

she keeps thinking over and over that she needs to clean her finger nails. The thought of microorganisms and dead skin cells underneath her nail makes her anxious. Every class she has to ask the teacher if she can go wash her hands. She brings a nail brush with her every time.
