16. What are the relations of the prostate gland?
17. What opens into the prostatic urethra?
18. The lymphatic drainage of the prostate is into superficial inguinal nodes.
19. Does the superficial perineal pouch extend into the penis? the scrotum?
20. What structures are innervated by the perineal nerve?
21. What are the boundaries of the perineum?
22. What are where is the perineal body? What muscles attach here?
23. What forms the floor and roof of the superficial perineal pouch?
24. What are the contents of the pouch?
25. What constitutes the urogenital diaphragm?
26. Name the parts of the male urethra?
27. In case of a ruptured bulbar urethra, where does the blood and escaped urine accumulate?
28. What occupies the ischio-rectal fossa?
29. What are the anal columns? What causes hemorrhoids?
30. Why is a strong levator ani muscle essential for normal perineal functions?
31. Why is pudendal block insufficient anesthesia for perineal surgery?
32. Why does adductor paralysis sometimes occur following childbirth?
33. Which of the vaginal fornices is the deepest?
34. What is an unusual obturator artery?
35. In both sexes, all parts of the urinary bladder are covered by peritoneum.
36. The lymphatic drainage of the penis is into superficial inguinal nodes.
37. The two components of the body of the penis are enclosed by the deep fascia of the penis.
38. The ischiocavernosus muscle covers the crura of the penis, or the crura of the clitoris.
39. The contents of the spermatic cord includes the vas deferns, two arteries, a venous plexus, a nerve, and lymphatics.
40. The lymphtic drainage of the anal canal above the pectinate line is to lumbar nodes, whereas the area below this line drains into the superficial inguinal nodes.
41. The female genital tract is mostly formed by the Wolffian duct. The Mullerian ducts form only functionless vestiges, (paroopheron, Gartner's duct, epoopheron) which can give rise to cysts.
42. The males genital ducts are derived from the Wolffian ducts. The Mullerian duct forms the prostatic utricle.
43. The descent of the testicle may be arrested. The testicle can remain stationary anywhere in the inguinal canal (cryptorchism).
44. Anomalies of the fusion of the Mullerian ducts produce such malformations as double uterus.
45. Hypospadia is caused by the failure of the genital folds to fuse.
46. Which perineal pouch is completely closed?
47. Which fascia bounds both the U.G. diaphragm and the superficial perineal pouch?
48. Name the nerve supply of the muscles of the superficial perineal pouch.
49. The fascia on the obturator internus contributes to the fomation of the pudendal canal.
50. The transpyloric line bisects a line bewteen the xiphoid process and the symphysis pubis.
51. The entire nerve supply of the scrotum is through branches of the pudendal nerve.
52. Can you trace the pathway of the spermatozoa beginning at the rete testis?
53. The testicular artery is the only blood supply of the testis.
54. The superficial inguinal lymph nodes are the first nodes involved in the lymphatic drainage of the male and female genital organs.
55. Name the parts of the uterus.
56. Define anteversion and anteflexion of the uterus.
57. All parts of the uterus are covered by peritoneum.
58. The pelvic cavity contains, aside from spinal nerves, only parasympathetic nerves.
59. The mesosalpinx is a separate entity, not related to the broad ligament.
60. The round ligament, when approaching the uterus, is outside the broad ligament.
61. The lymphatic drainage of the cervix is to external and internal iliac nodes and to sacral nodes.
62. The ovary has a dual blood supply.
63. The right ovarian vein drains into the inferior vana cava, whereas the left one drains into the left renal vein.
64. The ampulla of the Fallopian tube opens into the peritoneal cavity.
65. All walls of the vagina are of equal length.
