454 APPENDIX. 
6. The penis (p. 262, and Figs. 111 and 113). Cut the skin 
along the dorsum of the penis and reflect. Dissect the ligamentum 
suspensorium penis. Then introduce a bristle into the urethra and 
remove the integument from the whole penis and identify the corpora 
cavernosa and corpus spongiosum and the urethra. 
7. Remove the fat at the side of the rectum and find the levator 
ani muscle (p. 269, and Fig. 162, 11). Transect and reflect it. 
The internal sphincter ani (p. 269, and Fig. 113, 4). Find the 
external opening of the anal gland (p. 239); slit and examine it. 
8. Dissect the ischiocavernosus (p. 269) and bulbocavernosus 
(p. 271) muscles (Fig. 113), and find the bulbus of the corpus caver- 
nosum beneath the former. Cut it free from the ischial ramus. 
g. Clean the muscles from the pelvis on the side from which the 
crus penis is removed, and remove with bone forceps the body of the 
pubis and the ramus of the ischium. Then trace the neck of the 
bladder to its junction with the vasa deferentia, and the urethra from 
that point to the external opening (Fig. 111). Study the compressor 
urethra muscle (p. 271, and Fig. 113, ”). Find Cowper’s glands 
(p. 261) and the prostate gland (Fig. 113). Dissect the other muscles 
of the urogenital organs (pp. 268 to 273, and Fig. 113). 
10, Slit the urethra on one side throughout its length and find 
the veru montanum (p. 261); the openings of the vasa deferentia 
(p. 261), by bristles passed into the urethra from them; the openings 
of the prostate gland and the openings of Cowper’s glands. 
11. Study the structure of the penis (p. 262) by making a cross- 
section, and that of the glans by making a longitudinal section. 
Note, if possible, the os penis. 
C. Female Urogenital Organs (p. 263, and Fig. 112), The kidney 
and its ducts and the bladder are like those of the male (p. 255), 
except the neck of the. bladder, which will be seen in dissecting the 
uterus and vagina. 
a, Without cutting anything examine— 
1. The ovaries (p. 264); the ligaments of the ovary (p. 264, and 
Fig. 112). 
2. The uterine tube. Its ostium (p. 264). 
3. The body of the uterus (p. 266) as far as exposed. 
4. The cornu of the uterus. 
5. The broad and round ligaments of the uterus (p. 266). 
6. Slit open one Fallopian tube, cornu, and body of the uterus 
as far as the junction of the divisions of the body of the uterus. 
4. Remove the ventral wall of the pelvis on one side only and 
find the vagina and urogenital sinus (p. 267). The levator ani 
muscle (p. 269, and Fig. 162, 11) must be cut and reflected. 
1. Note the constrictor vestibuli, caudovaginalis, and urethralis 
muscles (p. 272, and Fig. 114). 
2. Introduce a probe from the uterus into the vagina and feel 
‘with the finger for the hard cervix uteri (p. 266). Then open the 
vagina on the side, but do not cut the os uteri (p. 266),
