(19) myf-5 is the only myogenic factor sequence present in the somite prior to muscle formation and thus is potentially involved in an earlier step of muscle determination.
(20) 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.
Tergite
Definition:
(n.) The dorsal portion of an arthromere or somite of an articulate animal. See Illust. under Coleoptera.
Example Sentences:
(1) By the structure of hypopigium males belong to the group of the species A. mariae and A. pulchritarsis but differ from the former in smaller basal warts and approximated lobes of IXth tergite and from the latter in the square shape of phallosome, approximated lobes and in the absence of the thorn on the basal wart.

(3) Mitotic recombination was X-ray induced in larvae and clones scored in the tergites of emerged adults.
(4) The adults are characterized by 4 dark postsutural mesonotal vittae, 1-2 bristles dorsally on the stem vein, the hairs on the ventral surface of r4 + 5 confined to the vein base, and the predominantly orange-yellow tergite I + II.
(5) The microtrichia of abdominal tergite six and sometimes four and five of the males of ten species of Sergentomyia (Subgenera Grassomyia, Sintonius, Sergentomyia and Parrotomyia) were found to be dimorphic.
(6) If P element mutagenesis creates additional variation for quantitative traits, accelerated response to artificial selection of progeny of M female female X P male male strain crosses is expected, compared with that from progeny of P female female X M male male strain crosses.--Divergent artificial selection for number of bristles on the last abdominal tergite was carried out for 16 generations among the progeny of P-strain males (Harwich) and M-strain females (Canton-S) and also of M-strain males (Canton-S) and P-strain females (Harwich).
(7) This is particularly striking in clones in the wing disc, slightly so in clones in the tergites.
(8) Labeled grafts were reimplanted into paired animals to detect cytotoxicity as follows: grafts removed from under the second tergite were placed back into their original positions to serve as autograft controls; grafts removed from under the fourth tergite were reciprocally transferred between paired animals; and grafts were recovered after various time intervals and processed for scintillation counting.
(9) The main consequences of treatment were failed eclosions at higher alkaloid concentrations (10(-4) M), while lower concentrations (10(-5) M) permitted the eclosion of adults, but these showed abdominal abnormalities ranging from severe distortions to reduced numbers of tergite bristles.
(10) Most of this pheromone is produced by cells whose precursors on the blastoderm surface are very close to, or identical with, the blastoderm precursors of the tergites.
(11) The cuticular pattern elements and pigmentation in the fifth sternite of the male housefly, when compared to those of other segments as well as the tergites of both sexes, are quite distinct.
(12) Both Minute and non-Minute adult progeny from Minute mothers suffer from Minute maternal effects such as abdominal segmentation defects, fused tergites, and missing or defective legs and halteres.
