Adrenaline

• Adrenaline occurs when you are put in a danger situation

• In these situation you can get full access to your muscles

• Adrenaline is caused by a single hormone

Scientific Derivation Of Adrenaline

• Lets assume you are in a dangerous situation, for example a bear comes to attack you

• This signals from our sensory neurons, that sense the situation from the eyes

• This is how sensory neurons function

• This is in the case of your hand and spinal

• The sensory with your eyes are different

• The sensory neurons signal the amygdala in the brain, why amygdala?, as amygdala plays a crucial role in the management of emotions

• When amygdala confirms threat, stress hormones are released and signals hypothalamus via glutamate ( neurotransmitter )

• Hypothalamus activates two arms:

  • Sympathetic Nervous System (immediate, via nerves)

  • HPA Axis (slower, hormonal)

Adrenaline Transfer

• The sympathetic nervous system is connected to the spinal cord

• From the spinal cord the signal goes to the adrenal medulla

• Preganglionic neurons originate in the central nervous system (CNS), specifically in the brainstem and spinal cord

• Preganglionic neurons from spinal cord travel to adrenal medulla

• 80% Epinephrine, 20% Norepinephrine in the blood is released

• after this your muscles are activated and then your blood over flows to the muscles and your heart pumps after to handle the situation
