SpletAs discussed in Section 2.6 of Chapter 2, the stomochord has attracted much interest as a notochord-like ancestral trait, ever since Bateson (1886) demonstrated it as a “hemi-chord.” It is a diverticulum of the anterior gut that extends into the posterior proboscis and is thought to support the heart–kidney complex along its dorsal surface (Fig. 9.1B; Fig. 1.3B). Splet22. okt. 2024 · Firstly, the developing notochord is always tightly attached to the ventral floor of the developing central nervous system. This is the case from its first appearance in stage 8 (17–19 days) until the definitive notochord is formed in stage 12 (26–30 days).
