Physiological Responses to Fight-Flight Mechanisms

Direction: You are to explain all the physiological responses, based on what we
covered this semester for the scenario given below. This should be written in APA
format. There are no limitations to how many pages you are allowed to complete
this in; however, it should be short, sweet, and simple, yet thoroughly covering
everything we mentioned in class this semester. Do not add new information
outside of what we learned in class. Turn in a typed hard copy on the day of the
final before examination is distributed. No papers will be accepted after this
time.
Scenario:
Sally was home and just had a huge meal. All of a sudden, she looks out the window
and sees a T-rex looking directly at her. Describe in detail what physiological
responses she is undergoing the moment she sees the T-rex. You should include
visual pathway along with sensation and perception, neural integration, down to
motor neuron processes and muscle contraction. You should also include gene
transcription and translation of neurotransmitters in the motor output.

( don't necessarily need you to do the assignment for me, need some pointers at where to start, how to start and what should i concentrate on.)
