| What organs are under only sympathetic control? |
|
Definition
Skeletal mucle(also Somatic NS) Radial muscle of iris (dilates/opend pupil) Sweat glands Liver, Adipose tissue, Kidney

Term
| What organs are under only parasympathetic control? |
|
Definition
Lacrimal gland(tear duct) Gastric acid and Pancreatic secretion Endothelium, releases EDRF
|
|
|
Term
| Decribe the filling and emptying of the bladder. |
|
Definition
Filling is done by sympathetic: - β2 relaxes the Detruror muscle to allow stuff in. - α1 contracts the internal sphincter(Trigone) to stop things from leaving. -External sphincter(skeletal muscle) is voluntarily contracted. Emptying is done by the parasympathetic: - Muscurinic contract the Detruror muscleto stop filling. -A seperate Muscurinic relaxes the internal sphincter(Trigone) to allow drainage. -External sphincter voluntarily relaxed. |
