sclerotome[′skler·ə‚tōm] (embryology) The part of a mesodermal somite which enters into the formation of the vertebrae. (medicine) A knife used in sclerotomy. (vertebrate zoology) The fibrous tissue separating successive myotomes in certain lower vertebrates. Sclerotome in chordate (including human) embryos, the inferior internal portion of a primary segment, or somite. A sclerotome consists of skeletogenous mesenchyma, which during embryonic development separates from the somite, surrounds the cord and the central nervous system, and forms an axial skeleton; in fish the skeleton of the paired fins is also formed by the mesenchyma. sclerotomeenUK
sclerotome [skle´ro-tōm] 1. an instrument used in incision of the sclera.2. the area of a bone innervated from a single spinal segment.3. one of the paired masses of mesenchymal tissue, separated from the ventromedial part of a somite, which develop into vertebrae and ribs.scle·ro·tome (sklē'rō-tōm), 1. A knife used in sclerotomy. 2. The group of mesenchymal cells emerging from the ventromedial part of a somite and migrating toward the notochord. Sclerotomal cells from adjacent somites become merged in intersomitically located masses that are the primordia of the centra of the vertebrae.
