vasomotor
Blood vessel control
Vasomotor describes the nerves and mechanisms that control the diameter of blood vessels, causing them to constrict or dilate.
The term appears most often in medical contexts: vasomotor rhinitis is nasal congestion caused by blood vessel changes rather than allergies; vasomotor symptoms like hot flashes result from sudden vessel dilation.
