What are integrative functions?
Define integrative function
the ability of the nervous system to analyze and interpret sensory information to allow for proper decision making, which produces the appropriate response.

How does a nervous impulse vary from a hormone signal?
Nervous impulse is much quicker. Occurring almost instantly. Where as a hormone signal is a little more delayed. (changing of a males voice during puberty as an example)
What type of neuron begins a reflex arc?

X
(Vagus Nerve)

Does massage increase or decrease sympathetic nervous system?
Regular massage prompts the body to move from sympathetic activity (fight or flight response) to parasympathetic activity (rest and digest response).
Both are parts of the Autonomic Nervous System (ANS)
Regular massage quiets the nervous system, which causes muscles to release. Released muscles, in turn, allow the mind to relax. (Body follows mind!) This results in the mind and body being healthier and more physically in tune for increased wellness.
Regular massage eases sore muscles and reduces stress that can constrict normal breathing. Deep, easy breathing naturally puts the body at rest.
What are some examples of body functions controlled by the autonomic nervous system?
Breathing, beating of the heart, digestion.
vagus nerve
