Cranial Nerves of Anolls carolinensis. 



PLATE 5. 



Fig. 12. Transverse section (No. 767) through the mid-orbit region. 

 The lingual and chorda tympani' nerves are leaving the alveolar canal. No 

 taste buds are found on the floor of the mouth, but they appear in the roof 

 of the mouth among the median palatine glands, and to a less extent along the 

 lateral glandular area. Different parts of the infraorbital plexus appear in the 

 floor of the orbit. 



Fig. 13. Transverse section (No. 909) through orbit, showing the connec- 

 tion of the optic nerve with the retina. The chorda tympani is closely applied 

 to the median side of the ramus alveolaris inferior. The muscle of the lower 

 lid {dep. palb. if.) shows some of its fibers originating from the connective 

 tissue near the median part of the roof of the mouth. 



Fig. 14. Transverse section (No. 988) through the anterior part of the optic 

 chiasma (blue tint omitted), showing entrance of ciliary nerves into the eye- 

 ball. The retina is cut tangentially; the infraorbital ganglion, the anterior 

 part of the lachrymal gland, and the mechanism of the bursalis muscle in its 

 relation to the ligament of the nictitating membrane, also fall in the plane of 

 the section. 



Fig. 15. Transverse section (No. 1064), posterior to the orbit, through the 

 posterior part of the optic chiasma (not lettered). The ciliary ganglion and 

 the lachrymal plexus around a large post-lachrymal blood sinus are shown. 

 The columella (epipterygoid) is cut where it articulates with the pterygoid 

 bone.
