PSNS SNS

Pharmacology

QuestionAnswer
PSNS- Heart decrease HR, decrease FC in atria only, decrease conduction velocity
PSNS-Blood vessels no innervation except at penis and vagina, NO causes dilation here
PSNS Eye tear secretion, miosis from contraction of circular muscle, near vision due to contraction of cilliary muscle (fat lens, zonules relaxed)
PSNS Respiratory tract contraction of smooth muscle-bronchoconstriction, increased bronchial and nasopharyngeal secretions
PSNS GI tract increased tone and motility, increased secretions, increased salvation
PSNS Endocrine none
PSNS Liver None
PSNS Urinary tract contraction of detrusor muscle (facilitates urination), relax sphincters
PSNS Reproductive Organs penile erection-dilation of blood vessels, increased mucous secretions
SNS Heart increased HR, increased FC in atria and ventricles, increased conduction velocity, increased automaticity
SNS Blood vessels constriction of arteries in most tissues with alpha receptors, dilation in those with beta receptors (licver and skeletal muscle)
SNS Respiratory Tract relaxation or bronchodilation
SNS Eye tear secretion, mydriasis (contraction of radial muscle). minor relaxation of ciliary muscle
SNS Skin Contraction of piloerector muscle, thermoregulatory, sweat gland stimulation
SNS GI relax muscle tone to decrease motility, decrease secretions, increase salvation
SNS Endocrine system inhibition a2 or slight stmulation b2 of insulin secretion
SNS Liver glycogenolysis a1 and gluconeogenesis b2 (increases availability of glucose)
SNS Kidney stimulate renin release b1, inhibit renin release A1
SNS Urinary tract relax bladder detrusor (inhibit urination) contract sphinctors
SNS reproductive organs constrict blood vessels, semen emission, relax uterus muscles

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
