Primary Receptor — Effector Organ

Question 1

B1 Receptors

Answer 1

Heart — INCREASES RATE OF CONTRACTION
Heart — INCREASES FORCE OF CONTRACTION
Heart — INCREASES CONDUCTION VELOCITY

Kidney — RENIN SECRETION

Fat Cells — LIPOLYSIS (also some B3 receptors)

** B1 — heart and kidney

Question 2

B2 Receptors

Answer 2

Blood vessels, skeletal muscle — VASODILATE

Bronchial tree — BRONCHIAL DILATION

Eye, ciliary muscle— RELAXATION, DILATION

Urinary bladder, Detrusor — RELAXATION
*detrusor muscle contracts during urination to push the urine out of the bladder and relaxes to allow filling of the bladder

Liver glycogenolysis — INCREASE (2ndary)

**B2 cells — relaxation or dilation of smooth muscle

Question 3

B3 Receptors

Answer 3

Fat cells — LIPOLYSIS (2ndary), B1 primary

Question 4

Alpha 1 Receptors

Answer 4

Arteries (most) — VASOCONSTRICTION (alpha 1 primary, alpha 2 secondary)

Veins — VASOCONSTRICTION (alpha 1 2ndary, alpha 2 primary)

Splenic muscle — CONTRACTION

UTERUS — CONTRACTION

Vas Deferens — CONTRACTION

Eye, radial muscle, Iris — CONTRACTION/DILATE (mydriasis)

Urinary Bladder, Trigone & sphincter — CONTRACTION

Ureter — CONTRACTION

Liver glycogenolysis — INCREASE (primary, B2 2ndary)

Hair follicles, smooth muscle — CONTRACTION (piloerection)

Nasal secretion — DECREASE (alpha 1 primary, alpha 2 2ndary)

Salivary glands — INCREASE SECRETIONS

Sweat glands — INCREASE SECRETIONS

Prostate gland, smooth muscle — CONTRACTION

** vasculature and prostatic smooth muscle = CONTRACTION

Question 5

Alpha 2 Receptors

Answer 5

Arteries (most) — VASOCONSTRICTION ( alpha 2 are 2ndary, alpha 1 are primary)

Veins — VASOCONSTRICTION ( alpha 2 are primary, alpha 1 are 2ndary)

GI tract — RELAXATION

Insulin release from pancreas — DECREASES

Nasal secretions — DECREASE (alpha 1 primary, alpha 2 2ndary)

Question 6

Cholinergic Response (Parasympathetic) mimics acetylcholine

Answer 6

Heart — DECREASES RATE OF CONTRACTION
Heart — DECREASES FORCE OF CONTRACTION
Heart — DECREASES CONDUCTION VELOCITY

Bronchial tree — BRONCHOCONSTRICTION
Bronchial tree — INCREASES BRONCHIAL SECRETIONS

GI tract — CONTRACTION (INCREASES MOTILITY)
GI tract — INCREASES SECRETIONS

Eye, circular muscle, iris — CONTRACTION (MIOSIS)
Eye, ciliary muscle CONTRACTION (Accommodation)

Urinary Bladder, detrusor — CONTRACTION
Urinary Bladder, Trigone & Sphincter — RELAXATION ( 2ndary, adrenergic primary)

Nasal secretions — INCREASE

Salivary glands — INCREASES SECRETIONS

Sweat glands — INCREASES SECRETIONS

Question 7

Adrenergic Response — mimics norepinephrine

Answer 7

Blood vessels, arteries — VASODILATION
Blood vessels, skeletal muscle — VASODILATION
Blood vessels, VASODILATION
** no inervation, but there are receptors in the endothelium of blood vessels causing contraction/dilation

Splenic capsule — CONTRACTION

Uterus — VARIABLE

Vas Deferens — CONTRACTION

Urinary bladder, Trigone & sphincter — RELAXATION (adrenergic primary, cholinergic 2ndary)

Ureter — RELAXATION

Insulin Release from pancreas — DECREASES

Fat cells — LIPOLYSIS

Liver glycogenolysis — INCREASES

Hair follicles, smooth muscle — CONTRACTION
