528 MALE PELVIS CONTENTS. 



brane, which is continuous with the lining membrane of the tubuli, 

 and forms a cup-like pouch, the calyx, around each papilla. 



The calices communicate with a common cavity of larger size, 

 situated at each extremity, and in the middle of the organ ; and 

 these three cavities the infundibula constitute by their union the 

 large membranous sac, which occupies the hilus renalis, the pelvis 

 of the kidney. 



The kidney in the embryo and foetus consists of lobules. See the 

 anatomy of the foetus in the succeeding chapter. 



The Ureter (ou^ov, urine, T%IV, to keep), the excretory duct of the 

 kidney, is a membranous tube of about the diameter of a goose-quill, 

 and nearly eighteen inches in length ; it is continuous superiorly 

 with the pelvis of the kidney, and is constricted inferiorly, where it 

 lies in an oblique direction between the muscular and mucous coats

* A side view of the viscera of the male pelvis in situ. The right side of the pelvis 

 has been removed by a vertical section made through the os pubis near to the sym- 

 physis; and another through the middle of the sacrum. 1. The divided surface of the 

 os pubis. 2. The divided surface of the sacrum. 3. The body of the bladder. 4. Its 

 fundus; from the apex is seen passing upwards the urachus. 5. The base of the blad- 

 der. 6. The ureter. 7. The neck of the bladder. 8, 8. The pelvic fascia ; the fibres 

 immediately above 7 are given off from the pelvic fascia and represent the anterior 

 ligaments of the bladder. 9. The prostate gland. 10. The membranous portion of the 

 urethra, between the two layers of the deep perincal fascia. 11. The deep perineal 

 fascia formed of two layers. 12. One of Cowpcr's glands between the two layers of 

 deep perineal fascia, and beneath the membranous portion of the urethra. 13. The 

 bulb of the corpus spongiosum. 14. The body of the corpus spongiosum. 15. The 

 right crus penis. 16. The upper part of the first portion of the rectum. 17. The rccto- 

 vesical fold of peritoneum. 18. The second portion of the rectum. 19. The right 

 vcsicula seminalis. 20. The vas defcrens. 21. The rectum covered with the descend- 

 ing layer of the pelvic fascia, just as it is making its bend backwards to constitute the 

 third portion. 22. A part of the levator ani muscle investing the lower part of the rec- 

 tum. 23. The external sphincter ani. 24. The interval between the deep and super- 

 ficial perineal fascia; they are seen to be continuous beneath the figure.
