cold causes constriction and decreased circulation to distal extremities;
“Functional” dysfunction (vasomotor disorder): spasms of the vessel walls; this is an example of…

A

abnormal dilation of greater than 50% normal size of the artery, vein or heart wall
Common causes: 
Trauma to the vessel wall
Congenital malformations
Infection
Atherosclerosis
