Term
AV node (heart) - parasympathetic
SN node + everywhere in heart |
|
Definition
M2 - slows heart
no significant effect on ventricles |
|
|
Term
| smooth muscle (eye, gut, bladder) |
|
Definition

Term
|
Definition
M3 - increase secretion
(sweat glands included, but are sympathetic innervation) |
|
|
Term
| SN+AV node (heart) - sympathetic |
|
Definition
B1 - speeds heart
ventricles poorly innervated |
|
|
Term
| ventricles (heart) - sympathetic |
|
Definition
B1 - increases conractility
responds to epinephrine because of poor innervation |
|
|
Term
| Small arterioles (skin, gut) |
|
Definition
A1 - increase blood pressure (resistance)
decrease blood to skin, gut |
|
|
Term
| Large blood vessels (skeletal muscle) |
|
Definition
B2 receptors - vasodilation
No parasympathetic or sympathetic innervation. Responds to epineprhine. |
|
|
Term
| Mixed blood vessels (epithelium of coronary and pial vessels [surface of the brain]) |
|
Definition
A2 - vasodilation
Innervated by SS, responds to NE,E |
|
|
Term
| Bronchial muscle (sympathetic and parasympathetic) |
|
Definition
Little SS innervation - lots of B2, responds to epinephrine for relaxation
Little PS innervation - M3, constriction |
|
|
Term
|
Definition
Radial muscle - A1 - dilation
Circular muscle - M3 - constriction |
|
|
Term
|
Definition
| PS only - M3 - Ciliary muscle contraction makes lens round and fat for near vision |
|
|
Term
|
Definition
A1 - sphincter contraction, no emptying
M3 - muscle contraction, emptying |
|
|
Term
|
Definition
A1 - contraction->ejaculation
richly innervated |
|
|
Term
|
Definition
Muscarinic - Erection
SS activation stimulates blood flow to facilitate erection |
