The neuroeffector properties of four blood vessels with diverse characteristics are compared and contrasted. The variables include the density and distribution pattern of sympathetic innervation; size, direction, and nerve frequency-characteristics of the neurogenic response, nature of the sympathetic transmitter, receptor types, and receptor-response coupling; and the level and temperature sensitivity of myogenic tone. In many instances, these features can be related to the functional role of the vessels and their pharmacological characteristics. The underlying basis of this diversification, with one exception, which can be related to developmental origin, is entirely unknown.
