PRACTICAL ANATOMY. 



Dissection. Place the subject in the proper lithotomy position, as described 

 previously for dissecting the male perineum. Thoroughly remove all pubic hair. 

 Find the following structures and dissect them in this order : 



1. TIic clitoris, homologous to the penis. 



2. The labia iiiajora, homologous to the scrotum. 



3. T/ie bulbo-cavcrnosus, homologous to the accelerator. 



4. The bulbi vcstibuli, homologous to the bulb of the urethra. 



5. The gland of Ilartliolin, homologous to Cowper's gland. 



6. TJic sphincter ani, the superficial transversus perinaji, and superficial part of 

 the triangular ligament. 



The Clitoris. The clitoris is homologous to the penis. Its size is often 

 underestimated, because the foreskin the labia minora binds it clown so you are

able to see only the distal end, called the glans. In the penis the prepuce 

 covers the glans and terminates below in a frenum ; in the clitoris the prepuce 

 terminates in the two elongated labia minora, owing to the vertical cleft of the 

 vaginal orifice. To dissect properly this organ, grasp the glans in the forceps of 

 your left hand, and, with the scissors in your right hand, cut the skin along the 

 dorsum of the clitoris for an inch upward. Then you can see the corona glandis 

 and the glans clitoridis in full view. Next remove carefully the skin from the 

 two crura along the ischio-pubic ramus. You will find these crura covered by a 

 muscle, the erector clitoridis, homologous to the erector penis. 



Remove the skin from the labia majora and trace the crescentic muscular fibres 

 of the bulbo-cavernosus muscle around the orifice of the vagina. This is the 

 sphincter muscle of the vagina. The transversus periiuei and sphincter ani are
