Plate 3-1 Open full size image SCROTAL WALL The testicles are maintained in position within the scrotal cavity by the structures of the spermatic cord. Each testicle and spermatic cord is invested in six distinct tissue layers that are acquired…
PELVIC STRUCTURES The relationships of male pelvic structures are illustrated in these complementary sagittal views—a paramedian and a median section. In the lower median view, the complete course of the urethra from the bladder to the meatus at the end…
Plate 1-1 Open full size image GENETICS AND BIOLOGY OF EARLY REPRODUCTIVE TRACT DEVELOPMENT Most living species have some form of sex-determination system that drives the development and expression of sexual characteristics in that organism. Sex determination can be genetic…
Plate 13-1 Open full size image POSITION AND STRUCTURE The breast is shown in its partially dissected state in the upper part of the plate and below in sagittal section. The size of the breast is variable, but in most…
Plate 12-1 Open full size image IMPLANTATION AND EARLY DEVELOPMENT OF OVUM Fertilization of the human ovum usually occurs in the ampullary portion of the oviduct, although in rare instances it may take place elsewhere in the genital tract or…
Plate 11-1 Open full size image THE OOCYTE AND OVULATION The completion of the final steps of meiosis I and the release of the oocyte from the parenchyma of the ovary constitute the process of ovulation. Through a process that…
Plate 10-1 Open full size image OVARIAN STRUCTURES AND DEVELOPMENT The ovaries develop from a thickening of cells that form ridges medial to the müllerian and wolffian bodies. These germinal ridges appear at the sixth week. Primary oocytes, arising in…
Plate 9-1 Open full size image FALLOPIAN TUBES The fallopian tubes are musculomembranous structures, each about 12 cm in length, commonly divided into the intramural, isthmic, and ampullary sections. The intramural (interstitial) portion traverses the uterine wall in a more…
Plate 8-1 Open full size image PELVIC VISCERA The interrelationships between the uterus and the surrounding muscles, nerves, vessels, and organs determine both the pathophysiology of uterine function and dysfunction in addition to the therapeutic modalities available when pathologies exist.…
Plate 7-1 Open full size image THE VAGINA The vagina (from Latin, literally “sheath” or “scabbard”) serves as the portal to the internal female reproductive tract and a route of egress for the fetus during delivery. The viscera contained within…
