4. Introduce a probe through the neck of the bladder and note its
emergence into the urogenital sinus.
5. Find the end of the clitoris (p. 267), and its prepuce, and then
dissect the integument carefully from about the external opening of the
urogenital sinus and note an external sphincter of the sinus (M. levator
vulvæ) (p. 272, and Fig. 114), equivalent to the levator scroti in the
male and continuous with the external sphincter ani.
6. Find (if possible) the corpora cavernosa of the clitoris (p. 267)
and the ischiocavernosi muscles (p. 269).
