MR. T. SNOW BECK ON THE NERVES OF THE UTERUS. 
231 
38.38.38. A branch of the sympathetic, which proceeds from the inferior aortic 
plexus (26, &c.), and is distributed to the middle part of the uterus (D), also sending 
a branch (39) to the ovary (E). The branch passes down by the side of the lateral 
hypogastric plexus (29.29), but without being at all connected with it in this subject, 
and then enters the broad ligament passing up to the middle part of the uterus. It 
is formed of gelatinous and tubular fibres. 
39. A branch which is sent to the ovary. Whether any branches come down from 
the renal plexus, in company with the spermatic artery, or not, I am unable to say, 
as the preparation was slightly injured in this part ; but I am inclined to think that 
there were branches supplied to the ovary as seen in Plate XV. 
40.40.40. Branches which pass from the lower border of the lateral hypogastric 
plexus to join the pelvic plexus. 
41. The lumbo-sacral nerve. 
42. Part of the ganglion on the sensitive root of this nerve. 
43. The first sacral nerve. 
44. The ganglion on this nerve. 
45. The second sacral nerve. 
46. The ganglion on this nerve. 
47. The third sacral nerve. 
48. The ganglion on this nerve. 
49.49.49. The ends of funiculi which form the fourth sacral nerve. 
50.50.50. Portions of the sacral plexus. 
51. A branch of the fourth sacral nerve (49.49) distributed to the levator ani (S). 
52. Branches from the third sacral nerve (47), which are distributed to the skin of 
the perineeum and labia majora (N). 
53. Some of the same branches, which, being divided, are turned aside. 
54.54.54. Branches from the third sacral nerve (47) distributed to the sphincter 
ani (R) and skin near the anus (P). 
55.55. Branches from the fourth sacral nerve (49.49, &c.) distributed to the mus- 
cular fibres and skin, at the lower part of the vagina. 
56.56. Large branches from the third sacral nerve (47) distributed to the clitoris (T). 
57.57. The continuations of the preceding branch (56.56). In consequence of this 
branch lying across the preparation it became necessary to divide it, and to turn the 
ends to each side. 
58.58. Branches of the sacral plexus which lie loose in the preparation. 
59. A branch from the second sacral nerve (45) which joins the pelvic plexus 
(61.61, &c.). 
60.60.60. Branches from the third sacral nerve (47) and from the fourth sacral 
nerve (49.49), which join the pelvic plexus (61.61, &c.). The branches from the third 
sacral nerve join the anterior part of the plexus, and are distributed to the bladder 
and tissues of the anterior part of the vagina, and those from the fourth sacral nerve
