| pampiniform plexus | <anatomy> A plexus formed, in the male, by veins from the testicle and epididymis, consisting of eight or ten veins lying in front of the ductus deferens and forming part of the spermatic cord. In the female the ovarian veins form this plexus between the layers of the broad ligament; in the male it is part of the thermoregulatory system of the testis, helping to keep the testis at a constant temperature slightly lower than the other body temperature. Synonym: plexus pampiniformis. (21 Jun 2000) |
