The primitive gut that forms during gastrulation in the developing blastula is known as the archenteron . It develops into the digestive tract of an animal. Formation of the Archenteron in Sea Urchins See Gastrulation . As primary mesenchyme cells detach from the vegetal pole in the gastrula and enter the fluid filled cavity in the center the blastocoel , the remaining cells at the vegetal pole flatten to form a vegetal plate . This buckles inwards towards the blastocoel in a process called invagination . The cells continue to be rearranged until the shallow dip formed by invagination transforms into a deeper, narrower pouch formed by the gastrula s endoderm . This narrowing and lengthening of the archenteron is driven by convergent extension . The open end of the archenteron is called the blastopore . File Protovsdeuterostomes.svg right thumb The Archenteron is labeled as the digestive tube The filopodia thin fibers formed by the mesenchyme cells found in a late gastrula contract to drag the tip of the archenteron across the blastocoel. The endoderm of the archenteron will fuse with the ectoderm of the blastocoel wall. At this point gastrulation is complete, and the gastrula has a functional digestive tube. The indentation that is actually formed is called the lip of the blastopore in amphibian s and fish , and the primitive streak in bird s and mammal s. Each is controlled by the dorsal blastopore , and primitive node also known as Hensen s node , respectively.

Posterior to the node is the primitive pit, where the cells of the epiblast the upper layer of embryonic cells initially begin to invaginate. This invagination expands posteriorly into the primitive groove as the cells layers continue to move into the space between the embryonic cells and the yolk. This differentiates the embryo into the germ layer s endoderm, mesoderm, and ectoderm. The primitive knot migrates posteriorly as gastrulation proceeds, eventually being absorbed into the tail bud. The cells of the primitive knot secrete many cellular signals essential for gastrulation including Fibroblast Growth Factor s, Sonic hedgehog , and retinoic acid . Cilia beating within the knot cause differential buildup of secreted factors in the nodal cavity, leading to development of the right left axis in the embryo.

Refimprove date October 2006 File Oocyte Poles.jpg thumb An oocyte with poles depicted In developmental biology , a blastula embryo is divided into two hemispheres the animal pole and the vegetal pole . The animal pole consists of small cells that divide rapidly, in contrast with the vegetal pole below it. The animal pole draws its name from its liveliness relative to the slowly developing vegetal pole. In some cases, the animal pole is thought to differentiate into the later embryo itself, forming the three primary germ layers and participating in gastrulation . The vegetal pole contains large yolky cells that divide very slowly, in contrast with the animal pole above it. The vegetal pole draws its name from its inactivity relative to the lively animal pole. In some cases, the vegetal pole is thought to differentiate into the extraembryonic membranes that protect and nourish the developing embryo, such as the placenta in mammals and the chorion in birds. In frog, Xenopus laevis pigment pattern provides the oocyte with features of radially symmetrical body with a distinct polarity. The animal hemisphere is dark brown, and the vegetal hemisphere is only weakly pigmented. The axis of symmetry passes through on one side the animal pole, and on the other side the vegetal pole. The two hemispheres are separated by an unpigmented equatorial belt. Polarity has a major influence on the mergence of the embryonic structures. In fact, the axis polarity serves as one coordinate of geometrical system in which early embryogenesis is organised. ref P. Hausen, M.

Unreferenced date December 2009 Triploblasty is a condition of the blastula in which there are three primary germ layer s the ectoderm , mesoderm , and endoderm . The germ layers form during gastrulation of the blastula . Additionally, the term may refer to any ovum in which the blastoderm splits into three layers. citation needed date January 2011 All higher and intermediate animals from flat worms to humans , arise from a triploblastic ovum. Triploblastic organisms are organisms which develop from such an ovum. Generally speaking, triploblastic organisms belong to the Bilateria subregnum. Triploblastic organisms generally possess bilateral symmetry, which is where the clade Bilateria takes its name. Simpler animals qualified as diploblasty diploblastic , such as cnidaria which include jellyfish, corals and hydra , possess two germ layers. Even simpler animals such as sea sponge sponges within the formally termed Porifera phylum contain no true tissues.

Unreferenced stub auto yes date December 2009 Invagination means to fold inward or to sheath. In biology , this can refer to a number of processes. Invagination is the morphogenetic processes by which an embryo takes form, and is the initial step of gastrulation , the massive reorganization of the embryo from a simple spherical ball of Cell biology cells , the blastula , into a multi layered organism , with differentiated germ layer s endoderm, mesoderm, and ectoderm. More localized invaginations also occur later in embryonic development, to form coelom, etc. Invagination is the formation of a cleavage furrow during cytokinesis in animal cells. The inner membrane of a mitochondrion invaginates to form cristae, thus providing a much greater surface area to accommodate the protein complexes and other participants that produce ATP. Invagination occurs during endocytosis and exocytosis when a vesicle forms within the cell and the membrane closes around it.
