Mass
Definition:

(v. i.) To celebrate Mass.
(n.) A quantity of matter cohering together so as to make one body, or an aggregation of particles or things which collectively make one body or quantity, usually of considerable size; as, a mass of ore, metal, sand, or water.

Sclerotome
Definition:
(n.) One of the bony, cartilaginous, or membranous partitions which separate the myotomes.
Example Sentences:
(1) From the survey of another 21 patients having bony abnormalities at the craniovertebral junction, the first type of arterial anomaly described above was seen in 4 patients and associated with failure of segmentation of the embryonic sclerotome such as occipitalization of the atlas or Klippel-Feil syndrome.
(2) In implants of either multiple rostral or caudal somite-halves, the grafted mesoderm dissociates normally into sclerotome and dermomyotome.
(3) In contrast, changes in the prevalence of N-CAM did not strictly accompany the remodeling of the somitic epithelium into dermamyotome and sclerotome.
(4) (2) When the transplantation reversed only the rostrocaudal axis, two days after the operation the rudiments of dorsal root ganglia were formed at the caudal (originally rostral) halves of the transplanted sclerotomes.
(5) In contrast, neural crest cells were never observed in the posterior sclerotome or in the perinotochordal space.
(6) In the remaining 11 cases multiple sclerotomes appeared to be involved and the clinical manifestations were correspondingly more severe.
(7) Adjacent to the caudal half of each somite, these cells penetrated no further than the myosclerotomal border, but opposite the rostral somite half, they were found next to the sclerotome almost as far ventrally as the notochord.
(8) The notochord and neural tube are well developed by 3 days and surrounded by sclerotome, myotome, and dermatome cells.
(9) The principal link in the formation of the viscero-cutaneous and viscero-sclerotomic sensation syndrome are transitory presynaptic terminals formed by the axons of the vegetative sensor neurons (cells of Dogel type 2) on the surface of the somatic receptor neurons innervating the skin and the sclerotomic tissues, and responding to temperature and pain.
(10) The results indicate the presence of three migratory routes in the trunk: (1) a ventral pathway through the anterior sclerotome; (2) a ventral pathway between the neural tube and the posterior sclerotome; and (3) a dorsolateral pathway between the somites and ectoderm.
