Jay has been afraid of dogs since he was bitten as a child. When he sees a dog, it sets off an intense reaction that involves both the nervous and endocrine systems. This is called the â??fight or flightâ? reaction because it prepares the person to fight off the danger or to run away.
Jay sees a dog and the visual signal is transmitted by neurons using (a)____ ___ signals inside the neurons and using chemicals called (b)__neurotransmitters__ between neurons. The signal arrives at and is processed in the (c)_occipital_ lobe of the brainâ??s cerebral cortex. A signal is also sent to a bean-sized central brain structure known as the (d)___pituitary gland___ which responds to strong emotions. Another brain structure, the hypothalamus, sends a signal to an endocrine gland called the (e)__________ that releases a hormone that in turn stimulates other endocrine glands. At the same time, the hypothalamus activates a branch of the peripheral nervous system known as the (f)___________ that increases heart rate, blood pressure, and breathing rate. Jay reacts by running away. To accomplish this, a signal is sent from the (g)________ lobe of the cerebral cortex through the (h)_______ branch of the peripheral nervous system to Jayâ??s leg muscles. Once Jay is safely away from the dog, his brain signals all systems to return to normal through the (i)_______ branch of the peripheral nervous system. Jay thinks about how lucky he was and plans what he will do next using the (j) _______ lobe of his cerebral cortex.
d should be amygdala, not the pituitary gland
a. action potential (your terminology may be different, but it is electric signals, ...
What kinds of changes occur in the brain that signal to the endocrine system during the fight or flight response? This question is answered in depth in the solution.
Stress management: theoretical perspectives
I'm quite frustrated with the assignment, as not much is explained in our text and I need some assistance or any sort of help at all.
"Explore the various theories regarding Stress and Stress Management from your textbook and the resources. Using the worksheet table, compare each theory of Stress/Stress Management. The table includes a column which summarizes the theories, another column which mentions the similarities, a column noting the differences and finally a column giving an example (you may add lines if necessary). Then write a short 3-5 paragraph synopsis of your matrix. Which theory do you think explains stress the best? Submit your matrix and your synopsis."
Specifically what I need for help is Walter Cannon's fight or flight response - I understand the theory, but when it comes to discussion, I am stuck. Please help me discuss similarities to other theories and differences from other theories. Starting to outline these items is where I find I have the most difficulty. I am also having difficulty with summarizing and transferring information.View Full Posting Details
