Block14/Fig. 8 & 9, NQ-3-d, Spermatic cord, h&e

block14_16.jpg - Fig. 8 & 9, NQ-3-d, Spermatic cord, h&eA unique feature of the spermatic cord is the presence of a plexus of atypical veins (pampiniform plexus; Fig. 8) that arise from the posterior side of the testis. The plexus is an anastomosing vascular network that constitutes the major component of the spermatic cord. The unusual feature of the veins is their thick muscular wall that, at a glance, gives the appearance of an artery (Fig. 9) rather than a vein. Careful examination of these vessels shows that the bulk of the vessel wall is composed of two layers of smooth muscle - an outer circular layer (OC) and an inner longitudinal layer (IL).
