Stage 22 Urogenital 3D Model
The individual serial slices have also been incorporated into a 3D model of this embryo [UG3dmodelst22.htm Urogenital System].

[../wwwhuman/lowpower/HumF/F3L.htm F3]: R testis with thick tunica albuginea (pale) and thin urogenital mesentery.Note spleen on L. | [../wwwhuman/lowpower/HumF/F4L.htm F4]: Testes. Narrow urogenital mesentery. Remains of mesonephric tubules near hilus (future efferent ductules at mediastinum testis). | [../wwwhuman/lowpower/HumF/F5L.htm F5]: Broader urogenital mesentery on R (still narrow on L). | [../wwwhuman/lowpower/HumF/F6L.htm F6]: On R: Remnants of mesonephric tubules (primordia of ductuli efferentes). Mesonephric duct (origin of vas deferens). Laterally, the paramesonephric duct (primordia of appendix testis). Note abdominal location of testes in relation to adjacent structures. |

[../wwwhuman/lowpower/HumF/F7L.htm F7]: Developing efferent ductules, mesonephric duct and medially, the paramesonephric duct (appearing solid). Note how the paramesonephric duct crossed the mesonephric duct ventromedially. Urogenital mesentery - note how testis is attached to the developing efferent ductules by a separate narrow flange,the mesorchium. | [../wwwhuman/lowpower/HumG/G1L.htm G1]: On R: Lateral mesonephric duct and medial paramesonephric groove. (Changing from a tube to a groove). On L: testis (lower than on R), mesonephric tubules, mesonephric duct (lateral), paramesonephric duct (ventromedial - appearing solid).Bladder. Umbilical arteries. Sigmoid colon and mesocolon. | [../wwwhuman/lowpower/HumG/G1L.htm G2]: Transition from abdominal cavity to superior pelvis. note iliac crest, femoral nerve, psoas major muscle, internal iliac vein and artery. Medial convergence of paramesonephric cords and more laterally-located mesonephric ducts, ventral to the colon and dorsal to the bladder. Note position of ureters. N.B. Testis lies above this level which is close to the plane of the future inguinal canal. | [../wwwhuman/lowpower/HumG/G3L.htm G3]: Transition from superior (major) pelvis to inferior (minor) pelvis. Rectovesical pouch. Note wide expanse of loose tissue ventral to the pubic symphysis: site of testicular descent. |

[../wwwhuman/lowpower/HumG/G3L.htm G4]: Transition from superior (major) pelvis to inferior (minor) pelvis. Rectovesical pouch. Note wide expanse of loose tissue ventral to the pubic symphysis: site of testicular descent. | External genitalia (male)[../wwwhuman/lowpower/HumG/G5L.htm G5]: Minor pelvis. Obturator foramen. Ischium. Head of femur. Acetabulum. Ganglion cells of pelvis plexus. Obturator externus muscle. Urogenital sinus (the caudal enlargement is due to junction of mesonephric ducts). | [../wwwhuman/lowpower/HumG/G6L.htm G6]:Level of pelvic floor. Pelvic plexus. Recto-anal junction. Ischium. obturator internus muscle. Greater sciatic notch. Alar of sacrum. Sacro-iliac joint. | [../wwwhuman/lowpower/HumG/G6L.htm G7]: Urethra opening ventrally. Genital tubercle (embryonic glans penis). |
