:You might find its to do with the sympathetic nervous system and the parasympathetic nervous system.
12.
The main inputs are the sympathetic and the parasympathetic nervous system ( PSNS ) and humoral factors.
13.
The second phase involves the activation of the parasympathetic nervous system, which involves the heart rate slowing.
14.
Basic physiology is studied, mostly endocrinology and the grand sympathetic nervous system, and the Parasympathetic nervous system.
15.
The autonomic nervous system has two branches : the sympathetic nervous system and the parasympathetic nervous system.
16.
The parasympathetic nervous system, through the action of vagus nerve, exerts a negative inotropic effect upon the heart.
17.
The parasympathetic nervous system experiences increased activity during REM sleep which may cause erection of the penis or clitoris.
18.
The end-result of baroreceptor activation is inhibition of the sympathetic nervous system and activation of the parasympathetic nervous system.
19.
There is also some evidence for postsynaptic receptors on sympathetic neurons allowing the parasympathetic nervous system to inhibit sympathetic effects.
20.
After the danger passes, another set of neurons, called the parasympathetic nervous system, takes over and releases the neurotransmitter acetylcholine.
