Bulbocavernous muscle (M. bulbocavernosus) (0. T. sphincter va- 

 ginae). This muscle extends from the perineal septum behind 

 to the clitoris in front. Note its homologue in the male. 



Ischiocavernous muscle (M. ischiocavernosus) (0. T. erector cli- 

 toridis).

Nerves of the perineum in the female (after Paulet.) (From Poirier et Charpy, Traite d'Anat. hum., 

 Paris, 1899, t. iii., 3, p. 1156, Fig. 594.) 



What is the perineal body 1 



Detach the M. bulbocavernosus and reflect it forward. The 

 M. transversus perinei superficial and M. ischiocavernosus 

 may also be detached. Study also 



(a) Bulb of the vestibule (bulbus vestibuli). 



The bulb will be found just beneath the M. bulbocavernosus. 

 Note its relation to the labia minora and urethra. Trace these ante- 

 riorly and note that the two oblong bodies forming the bulb are 

 united below the clitoris by an intermediate venous plexus (pars 

 intermedia of Kobelt). 



(b) Larger vestibular gland of Bartholin (glandula vestibularis major 



[Bartholini]). (Vide Spalteholz, Fig. 668.) 



Note the relation of this gland to the bulbous vestibule and 

 the M. bulbocavernosus. Dissect out its excretory duct and deter- 

 mine where it opens.
