Question

1. In the table below, summarize the effect of sympathetic or parasympathetic stimulation on the effectors in the first column. Thank you In Advance and I'll be sure to rate!

VISCERAL EFFECTOR	EFFECT OF SYMPATHETIC STIMULATION	EFFECT OF PARASYMPATHETIC STIMULATION
Eye
Salivary glands
Bronchi (lungs)
Heart
Adrenal medulla
Stomach and intestines, anal sphincter
Sex organs
Bladder/internal urethral sphincter
Liver
Erector pili muscles
Arterioles to intestines, kidneys
Arterioles to heart, skeletal muscles, liver

Answer 1

Effector organs	Parasympathetic system	Sympathetic system
Eyes	Pupils constriction	Pupils dilatation
Salivary glands	Increase secretion	Decrease secretion
Bronchi (Lungs)	Bronchoconstriction	Bronchodilatation
Heart	Decrese in Heart rate ,Decrease force of coduction,Decrease conductivity of heart	Increase in Heart rate,Increase in force of contraction ,Incresase conductivity through Heart
Adrenal medulla	Inhibitory action	Stimulate and release in adrenaline .Adrenaline stimulate the heart and increase heart rate,force of contraction and conductivity . Increase Blood pressure . Increase blood glucose
Stomach	Stimulate contractility ,motility and secretion .	Inhibits motility ,contractility and secretion.
Intestines	Increase intestinal motility and peristalis may result in diarrhea .	Decrease intestinal motility and peristalsis and result in constipation
An*s sphincters	Relaxation of anal sphincter	Contraction of anal sphincter.
Bladder	Increase contractility of blaader	Decrease contractility of blaader
Internal Urethral sphincters	Relaxation of sphicter and passsage of urine	Contraction of sphincter and retention of urine
Liver	Glycogenesis Parasympathetic function is to take rest and store energy	Glycogenolysis ,Gluconeogenesis.
Erector pili muscles	No innervation	Contracts of Muscles Piloerection ++ Goosebumps present
Intestine arterioles	Vasodilation	Vasoconstriction as supply of splanchnic circulation is Decreased .
Kidney arterioles	Vasodilation	Vasoconstriction
Heart arterioles	Arteriolar dilation	Arteriolar constriction
Skeletal muscles	Arteriolar constriction.	Arteiolar dilatation so increase blood supply to skeletal muscle help to fight against stress
Liver	Vasodilation	Vasoconstriction
Sex organs	Erection	Ejaculation

Basic funda -- Whenever there is situation like fight or fright stress like situation ,heart require sympathy and cause increase in its activity other places decrease in their activity .Parasympathetic increase activity everwhere except Heart .

Parasympathetic increase secretions from all glands ,tears ,increase motility of stomach and intestine ,ureters and relaxation of sphincters .

Sympathetic stimulation increase the blood supply to skeletal muscle by Vasodilation and vasoconstriction of splanchnic circulation .
