Does coronary vessels have both parasympathetic and sympathetic innervation?

Yes, coronary vessels have both parasympathetic and sympathetic innervation. Parasympathetic input leads to vasodilation of coronary vessels, while sympathetic input can cause vasoconstriction in response to stress or exercise. The balance between these two systems helps regulate blood flow to the heart.


Dilation and relaxation of the bronchioles are possible bcause of the presence of?

Beta 2 adrenergic receptors in lung tissue cause dilation of bronchioles via sympathetic stimulation.


What kind of stimulus might cause a reponse from your autonomic system?

The autonomic nervous system is in charge of involuntary functions. There are two divisions-the sympathetic and parasympathetic. The sympathetic nervous system initiates the fight-or-flight response in emergency situations. The parasympathetic nervous system is referred to as the "rest and digest" stage in which the body "slows down" after the fight-or-flight response.


What part of the PNS controls the pupillary response?

The autonomic nervous system, specifically the parasympathetic and sympathetic branches, control the pupillary response. The parasympathetic system causes pupillary constriction (miosis), while the sympathetic system causes pupillary dilation (mydriasis).


Does the autonomic nervous system may cause activation or inhibitiom depending on the division that is active and the target that is affected?

Yes, the autonomic nervous system can cause either activation or inhibition depending on whether the sympathetic division or parasympathetic division is active, and which target organ is being affected. The sympathetic division generally activates the fight-or-flight response while the parasympathetic division promotes rest and relaxation.


In what way do the parasympathetic and the sympatheticnervous systems work together?

Yes. The vagus nerve is a parasympathetic nerve that is almost always stimulating the healthy heart to have a heart rate less than the inherent rate of the SA node. The sympathetic innervation on the heart is minimal and only important during exercise.


Does parasympathetic nervous system cause slowed digestion?

it can cause you to die


Does increased parasympathetic activity cause blood pressure to increase?

no


Which part of nervous system cause increase salivary secretion?

Parasympathetic


What effect does the sympathetic and parasympathetic nervous system have on the digestive system?

The sympathetic nervous system inhibits digestive functions (fight or flight response), reducing blood flow to the digestive organs and slowing down digestion. The parasympathetic nervous system stimulates digestive functions (rest and digest response), increasing blood flow to the digestive organs and promoting digestion.


Can you die of fright?

Yes you can. Parasympathetic rebound is a possible reaction of the parasympathetic nervous system during intense fear. It can cause death. Some soldiers literally die of fear in combat.


What will sympathetic stimulation of the eye do?

Sympathetic stimulation of the eye will cause dilation of the pupil (mydriasis) and relaxation of the ciliary muscle for far vision.
