  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

Solutions

Expert Solution

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 .
