Sorry, no etymologies found.
In each of the provertebrae it is called the "sclerotome" (in opposition to the outlying muscular plate, the "myotome").
The cells of the segment become differentiated into three groups, which form respectively the cutis-plate or dermatome, the muscle-plate or myotome, and the sclerotome (Fig. 64).
The cells of the sclerotome are largely derived from those forming the core of the myocl, and lie next the notochord.
The lower or ventral part of each sclerotome (the inner and lower edge of the cube-shaped provertebra) divides into two plates, which grow round the chorda, and thus form the foundation of the body of the vertebra
