Summary
[edit]DescriptionGallus gallus domesticus (02).jpg | Fig. 156. Cleavage in chick blastoderm, sectional views. (After Patterson, '10.) (A) Median section through blastoderm approximately at right angles to furrow shown in fig. 155 A. (B) Section through blastoderm of about eight-cell stage. (C) Section through blastoderm, showing 32 cells, also showing horizontal cytoplasmic cleft (segmentation cavity). (D) Median section through blastoderm similar to that shown in fig. 155E. (E) Median section through blastoderm similar to that of fig. 155G. (F, G) Diagrammatic views of developing avian blastoderms. (F) Diagrammatic section and surface view of chick blastoderm shown in fig. 155G and fig. 156E. (G) Section of chick blastoderm about time that egg is laid, depicting the primary blastocoel below the blastoderm and syncytial tissue at the margins. Observe that the syncytial tissue serves to implant the blastoderm upon the yolk substance. |
