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.
[sclero- + G. tomē, a cutting]

sclerotome

[sklir′ətōm]
Etymology: Gk, skleros + temnein, to cut
(in embryology) the part of the segmented mesoderm layer in the early developing embryo that originates from the somites and gives rise to skeletal tissue of the body, specifically the paired segmented masses of mesodermal tissue that lie on each side of the notochord and develop into the vertebrae and ribs. See also somite.

DISCUSSION: The vertebral column develops from paired somites, each composed of a dermatome, myotome and sclerotome.
The last theory was probably proposed to explain the common occurrence of this disorder in particular sclerotomes.
Within a limb, melorheostosis is usually confined to a single sclerotome and even within a particular sclerotome, the lesions may cross the joint space to involve bones on either side but the intervening joint is usually not involved (5).
