Somites
[Gr. somatikos - of or for the body]. Segmented mesodermal blocks located on either side of the developing spinal cord which arise from the dorsal mesoderm.
somites Mesodermal structures formed during embryonic development that give rise to segmented body parts such as the muscles of the body wall.
special senses Vision, hearing, taste, and smell.
somite - block of dorsal mesodermal cells adjacent to the notochord during vertebrate organogenesis.
somite
A serial segment of the animal body.
sorus (pl. sori)
A group of sporangia developed on the underside of sporophylls (spore-bearing leaflets) of the sporophyte generation of a fern.
somite One of the blocklike masses of mesoderm arranged segmentally (metamerically) in a longitudinal series beside the neural tube of the embryo; metamere.
sonar A technique or equipment used to locate objects underwater by the detection of echoes.
Soma (somatic cells) Somatic-cell nuclear transfer (SCNT) Somatostatin SomiteOne of the blocks of mesoderm that develop in a longitudinal series on either side of the notochord in vertebrate embryos.
After one month the embryo is 5 mm long and composed mostly of paired somite segments. During the second month most of the major organ systems form, limb buds develop. The embryo becomes a fetus by the seventh week.
The mesoderm forms the somites, the notochord, and the mesenchyme, which give rise to the muscles, circulatory and excretory systems of the body.
The maternal effect is a phenotype of severe neural kinking, accompanied by somite abnormalities, suggesting again, a role in the determination or maintenance of the integrity of the body axis.
