[Cability of the neuro-muscular spatial relationships in the wall of the blood vessels].
Electronmicroscopic studies have been made on the distribution of the nervous fibers in the wall of the constricted and dilated auricular artery of the rabbit. It was demonstrated that during the dilatation of the vessel, the dimensions of the neuro-muscular cleft decrease. In the constricted artery, 50% of the nervous fibers are found in the adventitial zone which has a thickness of 4.6 mu. In the dilated vessel this zone decreases up to 1.8 mu. It is suggested that this mechanism is responsible for the regulation of the blood vessel tone.
