370 DISSECTION OF THE RABBIT. 



vulva. Its walls are very vascular, and corre- 

 spond to the corpus spongiosum in the male. 



d. The clitoris is a small rod-like body, corresponding 



to the penis of the male, and lying in the anterior 

 or ventral wall of the vestibule, just within its 

 external opening. In the rat it is traversed 

 by the urethra. It ends in a soft conical body, 

 the glans clitoridis, and is connected with the 

 ischia by two corpora cavernosa similar to those 

 of the male, but smaller. 



e. Cowper's glands are reduced or absent. 



f. The perinseal and rectal glands are similar to those 



of the male (p. 368). 



Slit up with scissors the vestibule and the hinder part of 

 the vagina along one side. Note the great vascularity of the 

 walls, the position and relations of the clitoris, and the opening 

 of the bladder into the vestibule. 



Slit up the anterior part of the vagina along the mid-ventral 

 line, to expose the openings of the uteri into the vagina. Note 

 the very prominent lips of these openings. 



VIII. DISSECTION OF THE NECK. 



A special dissection of the neck is desirable, on account of 

 the great importance of the structures contained in it, more 

 particularly the nerves (see fig. 65, p. 374). 



Lay the rabbit on its back on a dissecting -board ; and pin 

 back the head so as to extend the neck fully. Make a median 

 ventral incision through the skin of the neck, and dissect the 

 skin away from the underlying parts, taking care not to 

 damage the muscles. Keep the dissection moist. 



A. The Hyoid Bone. . . 



The body of the hyoid is a transverse bar of bone, deeply 

 placed between the rami of the mandible, and about midway 

 between the hinder end of the mandibular symphysis and 

 the angles of the jaw.
