Cards

Term
NicotinicN
Definition

Location: All autonomic nervous system ganglia and the adrenal medulla

Response to activation: Stimulation of parasympathetic and sympathetic postganglionic nerves and release of epinephrine from the adrenal medulla

Term
NicotinicM
Definition

Location: NMJ

Response to activation: Contraction of skeletal muscle

Term
Muscarinic
Definition

Location: Eye

Response to activation:

Contraction of the ciliary muscle focuses the lens for near vision

Term
Muscarinic
Definition

Location: Eye

Response to activation: Contraction of the iris sphincter muscle causes miosis (decreased pupil diameter)

Term
Muscarinic
Definition

Location: Heart

Response to activation: Decreased rate

Term
Muscarinic
Definition

Location: Lung

Response to activation: Constriction of bronchi

Term
Muscarinic
Definition

Location: Lung

Response to activation: Promotion of secretions

Term
Muscarinic
Definition

Location: Bladder

Response to activation: Contraction of detrusor increases bladder pressure

Term
Muscarinic
Definition

Location: Bladder

Response to activation: Relaxation of trigone and sphincter allows urine to leave the bladder

Term
Muscarinic
Definition

Location: Bladder

Response to activation: Coordinated contraction of detrusor and relaxation of trigone and sphincter causes voiding of the bladder

Term
Muscarinic
Definition

Location: GI tract

Term
Muscarinic
Definition

Location: GI tract

Response to activation: Erection

Term
Muscarinic
Definition

Location: Blood vessels

Response to activation: Vasodilation

Term
Alpha1
Definition

Location: Eye

Response to activation: Contraction of the radial muscle of the iris causes mydriasis (increased pupil size)

Term
Alpha1
Definition

Location: Arteriole (skin, viscera, mucous membranes)

Response to activation: Constriction

Term
Alpha1
Definition

Location: Veins

Term
Beta1
Definition

Location: Heart

Response to activation: Increased rate

Term
Beta1
Definition

Location: Heart

Response to activation: Increased force of contraction

Term
Beta1
Definition

Location: Heart

Term
Beta2
Definition

Location: Liver

Response to activation: Glycogenolysis

Term
Beta2
Definition

Location: Skeletal muscle

Response to activation: Enhanced contraction, glycogenolysis
