This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1910 Excerpt: ...the two or three vesicles, vs., noted in the preceding figure. These vesicles are not connected with either paraphysis or fore-brain. When followed laterally the velum is seen to expand to form, on each side, a much branched structure, the plexus of the lateral ventricle, figures 5a and 5b, c. p. Figure 53 represents a section laterad to the one just described. It passes through the median edge of the choroid plexus, c. p., just described, and through the lateral portion of the paraphysis, p., whose walls appear thick merely because cut tangentially. Figure Sb is a section of a somewhat older embryo than the one shown in figures 5 and 53. It is about, though not exactly, in the plane a-b of figure 5. It shows the laterally compressed paraphysis, p., and in each lateral ventricle, c., the much convoluted plexus, c.p. Figure 6 shows the paraphysal region of an embryo of about 7 cm. length. This embryo is several times the length of the one represented by figure 5, and has practically the external form of the adult, even the pigmentation of the skin being partially formed. In spite of this great advance in general development, about the only change in the paraphysis, p., is a slight increase in length. Its walls are still practically smooth and unconvoluted; they are composed of a simple columnar epithelium. The velum, v., has, in this median plane, nearly the same appearance as in figure 5; in it are seen four or five of the same small vesicles, vs., lined with cuboidal cells, that were seen in figures 4 and 5. The prolongations of the velum into the lateral ventricles, the choroid plexuses, as seen in more lateral sections, are now large and much convoluted. The post-velar arch, v. a., is much reduced in extent, so that the distance between the posterior com...
