. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. mv- ..... ;•,•• . - . -•. FIG. 8. Section of crista acustica of one of the ampullae of a chick of eight days incubation. (X 235.) , ganglion cells. , nerve tract running from crista to brain. Other abbreviations as in Fig. ~. appearing in two places, separated by the host mesenchyme. The character of the cellular differentiation is distinctive. In one of the groups, the differentiation is like that of the ductus and saccus endolymphaticus. These structures are connected, the ductus appearing as a tube leading from the saccus. Xear these, a canal-like formation appears for a few sections These parts are not widely separated from the other group of structures which are adjacent to the mass of cartilage. The parts in this group are in the form of distinct vesicles and tubules, resembling histologically, utriculus, sacculus and a small portion of a canal. In the utricular wall are two areas interpreted as crista? acu>ti-M-. one of which is associated with the canal-like portion already mentioned. It would seem therefore, from the data given for the a!»o\e cases, that the differentiation of the constituent parts of the otic vesicle is very specific, and that it takes place independent of i he relationships of the various parts, which depend on mechanical Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
