Cholinergic receptors (parasympathetic and sympathetic)

Eye

Contraction of the iris sphincter muscle (pupil contracts)

Contraction of the ciliary muscle (lens accommodates for near vision)

Trachea and bronchioles

Constriction, increased secretions

Uterus and bladder

Contraction of detrusor; relaxation of trigone and sphincter

Genitalia (male)

Stimulation of erection

Lacrimal glands

Stimulation of tears

Salivary glands

Copious, watery secretion

Heart

Decreased rate; decreased contractility

Gastrointestinal system

Increased muscle motility and tone

Eye (s)

Contraction of iris radial muscle (pupil dilates)

Dilation

Adrenal medulla (s)

Secretion of epinephrine and norepinephrine

Kidney (s)

Secretion of renin (beta1: increases ; alpha1: decreases

Ureters and bladder (s)

Relaxation of detrusor; contraction of trigone and sphincter

Genitalia (male) (s)

Stimulation of ejaculation

Salivary glands (s)

Thick, viscous secretion

Heart (s)

Increased rate; increased contractility

Gastrointestinal system (s)

Decreased muscle motility and tone; contraction of sphincters (mawagtangan kag appetite)

Genitalia (female) (s)

Relaxation of the uterus

Blood vessels (skeletal muscle) (s)

Dilation

Blood vessels (skin, mucous membranes, and splanchnic area) (s)

Constriction
