Peculiarities of uretral pacemaker zones innervation

Abstract

Peculiarities of extra-intraorgan innervation of uretral pacemaker zones (upper and lower urethral narrowings) were investigated. Anatomic-histological investigation results showed that upper (the I order pacemaker) and middle (the II order pacemaker) pacemaker zones of the ureter are innervated by single nerve stems from lower aortic-renal ganglion of plexus nervosus. Presence of microganglia in their intramuscular plexus nervosus is the peculiarity of intraorgan innervations of uretral pacemaker zones. The data obtained contribute to cystoid-peristaltic theory of uretral motility organization.
