You are walking in the forest…

What information is being detected by you/your body?

Propose two external and two internal examples. How is the information being detected? I'm looking for detail here...

Stimulus, detector, transduction mechanism...

What physiological systems are involved – and can you describe the system using the following hierarchy (with examples)?

System
Organ/s
Tissue/s
Cells/s

Expert Solution

Answer:

In the middle of forest, the sound of twig snap can elicit fight of flight response from the body.
There can be multiple reasons for twig snap, an animals on tree or a a tree branch is falling on you, whatever may be its a potent dangerous condition.
Hence body must decide whether to fight or flight.

System:

The first response comes from the nervous system - systemic nervous system, amygdala.
It activates hypothalamus gland to further activate SAM and SNS pathway of endocrine system.
Now, adrenal medulla a part of adrenal gland located above kidney is activated. Adrenal glands released hormones epinephrine and norepinephrine into blood stream.
These hormones are taken up by the organ Liver, where the hormones trigger glycogen breakdown and release of glucose into blood.

Organs:

Lungs, : increased breathing, increased oxygen intake
Heart, :increased blood pumping, rapid breathing,
Kidney: Decreaeed urine output, increased water retention
Liver: conversion of glycogen into glucose
Brain: releasing hormones and activating nervous system

Tissue:

Skin: increased sweating, skin pale.
blood: vasodilation, increased blood flow to lower extremities.
pupil of eyes: size of pupils increased to intake more light
spinal cord: increased impulses to motor cells and muscles
muscle: increased blood flow or decreased depending on hormone response.

Cells:

liver cells: increased glycogen breakdown
Hypothalamus and pituitary gland cells: releasing hormones into blood stream
sweat glands: increased sweat production

Overall physiological effects would be increase in heart rate, increased breathing rate, sweating, dilated pupils...etc.
