Fight or flight situations are dominated by the?
Sympathetic nervous system that releases epinephrine (adrenaline).
What is permissive action as in the nervous system?
sdsgs

epinephrine (or adrenaline in the UK) mimics the effects of norepinephrine (noradrenaline in UK), so activates the SNS, not the PSNS.
What are drugs that mimic the sympathetic nervous system?
norepinephrine/noradrenaline working in tandem with epinephrine/adrenaline

What is an example of an effector?
In biology, an effector is an organ that reacts to the external stimuli on receiving signals from the central nervous system. An example is when the adrenal gland secretes adrenaline in response to stress or danger.

Neurotransmitter released in response to stress?
The endocrine system releases adrenaline when the nervous system experiences stress
Can a person release adrenaline on their own?
No. Adrenaline is released in response to the autonomic nervous system. 'Autonomic' indicating that it is an automatic process regulated by the body and is not under voluntary control. Other components of the nervous system, such as the somatic nervous system, are able to be voluntarily controlled. Adrenaline release is regulated by the sympathetic division of the autonomic nervous system. Adrenaline is released in response to various stimuli such as: exercise, stress, fear, decreased blood pressure (including blood loss), and more. B.) Yes , there are some few people in the world have it they can release a small amount on their own but not like when they are in fear or rush.
What kind of action is a sneeze?
It is a reflex action which is an autonomic (automatic) nervous system reaction to stimuli. It is the respiratory system and the nervous system working together. The pepper is an irritant to the nasal mucosa and it signals to the brain to sneeze and get it out of there. Another example of a reflex action is when you touch something extremely hot....you quickly pull your hand away.
What is an example of the nervous system helping your body to maintain steady conditions?
The nervous system helps keep steady body conditions by telling the body how to respond to the information it gets. For example when you are hungry, your nervous system tells you to eat. This action maintains steady body conditions by giving your body the nutrients and energy it needs.
