Lutz, of the exposed mesentery and bladder of the frog. Contractility of the arterioles, with typical circularly arranged smooth muscle ceils and abundant sympathetic innervation, is generally accepted. The controversial point has been how important a role the capillary, with its longitudinally arranged adventitial cells and sparse sympathetic supply, plays in variations in the peripheral distribution of blood.en-USBased on investigation of the BU Libraries' staff, this work is free of known copyright restrictionsThesis/Dissertation
