Consequently, what is the dorsal blood vessel attached to?The dorsal blood vessel runs along the length of. The ventral blood vessels are responsible for carrying blood to the back of the earthworms body. The dorsal blood vessels are responsible for carrying blood to the front of the earthworms body. The forearm has two muscle compartments, the dorsal compartment (in which the extensor/supinator muscle group resides) and the ventral compartment (in which the flexor/pronator muscle group resides.) Notice how we see mostly extensor/supinators on the dorsal side, but a few flexor/pronators creep over there. In this manner, what is a DISI deformity?A DISI deformity is a condition in which there is a mutual change in position of two carpal bones in. What is dorsal intercalated segment instability?ĭorsal intercalated segment instability (DISI) is a deformity of the wrist where the lunate angulates to the posterior side of the hand. Weak or overstretched muscles in the upper thoracic area account for many cases of dorsal kyphosis. The slang term for this phenomenon is a hunchback. Word origin: from Greek (blastos), meaning "sprout" See also: blastula.ĭorsal kyphosis is a technical term for a very common phenomenon, which is that of a rounded upper back posture. ![]() It is marked by the presence of a blastocoel. It entails cleavage resulting in a blastula consisting of about 128 cells. Likewise, people ask, what is Blastopore?īlastopore, the opening by which the cavity of the gastrula, an embryonic stage in animal development, communicates with the exterior.īlastulation is the process following the morula and precedes the gastrulation. Gastrulation is a phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a multilayered structure known as the gastrula. Subsequently, question is, what is the process of gastrulation? Gastrulation occurs when a blastula, made up of one layer, folds inward and enlarges to create a gastrula. As these first cells pass into the interior of the embryo, the dorsal blastopore lip becomes composed of cells that involute into the embryo to become the prechordal plate (the precursor of the head mesoderm). ![]() These cells later become the pharyngeal cells of the foregut. the dorsal marginal region of the blastopore, which acts as a center of differentiation: as cells move through this region to the interior of the embryo during gastrulation, they acquire the ability to induce the overlying ectoderm to develop into a variety of tissues.Īlso to know is, what does the dorsal lip become?
