Besides, what is the dorsal lip?
Definition of dorsal lip. : the margin of the fold of blastula wall that delineates the dorsal limit of the blastopore, constitutes the primary organizer, and forms the point of origin of chordamesoderm.
Similarly, how is the dorsal lip specified? These cells form the dorsal lip of the blastopore. The cells of the dorsal lip are committed to invaginate into the blastula, thus initiating gastrulation and the formation of the notochord. He found that the cells of the early gastrula were uncommitted, but that the fates of late gastrula cells were determined.
Then, what does the Archenteron become?
archenteron. archenteron A primitive digestive cavity of the embryo at the gastrula stage of development in animals. It is formed by invagination of mesoderm and endoderm cells, opens to the outside by a blastopore, and finally develops into the gut cavity.
What is the role of dorsal lip of Blastopore as primary organizer?
The dorsal lip of blastopore (chordamesoderm) acts as the primary organizer. The chordamesoderm of a neurula stage is used as the implanted material. The anterior portion used as graft into the blastocoel induces a head, while the posterior part as a graft produces a secondary trunk and tail.
