478 ANATOMICAL TECHNOLOGY. 



1224. Endyma, me?. Fig. Ill, 112, 121-123 ; 1079. Gray, A, 630 ; Quain, A, 

 II, 540. 



Syn. Ependyma, pia mater interior. 



The epithelial lining of the crelise, which is reflected upon the plexuses. 



1225. Epencephalon (az.), epen.Fig. 88, 104, 110-114, 117; PI. I, Fig. 1, 2; PI. II, 

 Fig. 3, 4; PI. Ill, Fig. 12 ; PL IV, Fig. 15. Gray, A, 111 ; Quain, A, II, 755. 



The encephalic segment including the cerebellum, pons, pedunculi, valvula, and the cor- 

 responding part of the " medulla." 



While it is convenient to recognize the segment, its precise limits are difficult to 

 assign, and Spitzka (7, 165) inclines to abandon the segmental name altogether. If the 

 caudal boundary coincides with the margin of the pons, the trapezium of man will be 

 included therewith, while that of the cat remains in the meteucephalon. 



1226, Epiccelia (az.\ epc.Fig. 110-113, 117 ; PL II, Fig. 4; 1141. Gray, A, 635 ; 

 Quain, A, II, 512. 



Syn. Ventriculus quartus or fourth ventricle, the cephalic part ; ventriculus cerebelli. 

 The cavity of the epencephalon, covered by the cerebellum and valvula. 



1237. Fasciola, fsd.Flg. 121 ; PL IV, Fig. 14, 17. Gray, A, 627 ; Quain, A, 

 II, 545. 



Syn. Fascia dentata, fasciola cinerea. 



The somewhat thickened margin of cinerea along the fimbria. In man the ventral 

 portion has commonly been called fascia dentata ; in the cat, however, there is no denticu- 

 lation, and the name fascia is certainly misleading ; hence the senior author proposed 

 (?>, 135) to employ fasciola for the whole. 



1228. Fimbria, fmb. Fig. 121 ; PL IV, Fig. 14, 17. Gray. A, 627; Quain, A, II, 

 542, 544. 



Syn. Corpus fimbriatum, taenia hippocampi. 



The strip of alba forming the border of the hypocampa and one of the boundaries of 

 the ritna. See fornix ( 1238). 



1229. Fissura ansata, F. an. This and the other cerebral fissures (including all 

 the fissures named in 1129 excepting the four appertaining to the myeloii) are briefly 

 discussed in the last part of this chapter. See especially the Table of Synonyms ( 1342). 



1230. Fissura dorsilateralis (myelonis), F. dl Fig. 112; PL I, Fig. 1. Gray, A, 

 605 ; Quain, A, II, 493.

1232. Fissura ventrilateralis, F. vl.Fig. 112, 116 ; PL II, Fig. 3. Gray, A, 605 ; 

 Quain, A, II, 493. 



1233. Fissura ventrimesalis (az.\ F. vms.F'ig. 99, 100, 109, 112 ; PL II, Fig. 3. 

 Gray, A, 605 ; Quain, A, II, 493. 



The " anterior fissure of the cord." 



1234. Flocculus, ^c.-Gray, A, 634; Quain, A, II, 518. 



We are not sure that this is represented in the cat, although it has been homologized 

 by some with the Lobulus appendicularis. 



1235. Foramen caecum (az.), Fm. ce.Pl. II, Fig. 3,4. Gray, A, 610; Quain, A, 

 II, 504. 



Syn. Fossa cca Spitzka, 3, 6.
