Chapter 2 homework How Do Our Brains Communicate With Our Bodies? Topic: Brain and Behavior Due: September 28, 2018 Title: Write a Seript The activity is to write a script consisting of dialogue between various parts of the brain and body. So, the "actors" become things like the central nervous system the brain, the spinal cord, neurotransmitters, and so on You are to "set the scene" as to what is occurring before the dialogue takes place. . For example. "Mary is in class and hears the fire alarm," or Tery is cooking and Then, write out an explanation of what happens in the brain and body through your script. You are literally explaining how the brain and body "talk" to each other. Your "characters" are the PNS system (sympathetic and parasympathetic divisions of the nervous system).

Answer 1

Answer.

Scene: Terry comes in contact with a scalding hot pan while cooking and instantly drops the pan on the floor.

Sensory neurons in the finger: ah-oh, I think we have been exposed to something serious this time. I can feel intense eta waves running all over me! Quick we need the help of the frontal cortex in the Brain to interpret this based on past learning.

sensory neurons of the parasympathetic nerves: may be its best that we consult the spinal cord about it. It will be quicker. What if it requires an immediate response in the form of a reflex?

Sensory receptor: ok lets do that then.

Parasympathetic nerve: i’ll Go immediately to the Spinal cord!

( as the parasympathetic nerve gets stimulated by the sensory receptors in the hand and carry the message to the reflex arc spinal cord, they make contact with the basal ganglia in the spinal arc)

Parasympathetic nerve: quick! Terry’s hand has made contact with something which appears to be hot. What can be done?

Interneurons of the reflex arc: oh no! Terry has done it this time. I have picked some very strong electrical impulses from you parasympathetic nerve. This object can burn her hands if she continues to hold it. We need to inform the motor nerve immediately.

(A corresponding set of motor neurons of the parasympathetic system that shoot from the reflex arc are stimulated by the interneuron. They terminate in the hands and stimulate the reflex action of dropping the hot pan.

Motor nerve to hand: Hand, quick save yourself and drop that object at once!

(The necessary action is carried out and Terry retracts her hand from the hot pan and drops it on the floor in a spontaneous reflex)
