Definition:
(a.) Of or pertaining to an embryo; embryonal; rudimentary.

(15) p50B is able to form heteromeric kappa B-binding complexes with RelB, as well as with p65 and p50, the two subunits of NF-kappa B. Transient-transfection experiments in embryonal carcinoma cells demonstrate a functional cooperation between p50B and RelB or p65 in transactivation of a reporter plasmid dependent on a kappa B site.
(16) At the adult neuromuscular junction, acetylcholine (ACh) receptors are highly localized at the subsynaptic membrane, whereas, embryonic myotubes before innervation have receptors distributed over the entire surface.

Myotome
Definition:
(n.) A muscular segment; one of the zones into which the muscles of the trunk, especially in fishes, are divided; a myocomma.
(n.) One of the embryonic muscular segments arising from the protovertebrae; also, one of the protovertebrae themselves.
(n.) The muscular system of one metamere of an articulate.
Example Sentences:
(1) To improve the slightly disappointing voice rehabilitation results of the myotomized laryngectomees, a modified myotomy is proposed.
(2) Root anatomy and the concept of myotomes and dermatomes are reviewed, as is the pathophysiology of radiculopathy.
(3) The possible relationship of these data with the appearance of mononucleated differentiated cells in myotomes in vivo and the possible neural control of this stage of myogenesis are discussed.
(4) Parasagittal sections of the caudal myotomes of 10.5-d-old embryos showed that expression of contractile proteins preceded the expression of myogenin or MyoD and, when coexpressed, MHC and myogenin did not co-localize within all the cells of the myotome.
(5) "Ventral nerves" are seen on the midmedial surface of each myotome.

(8) Serial sections of stage 18-27 HH (3-5 days of incubation) chick embryo myotomes were investigated by electron microscope.
(9) The map may be important for the proper control of the many muscles arising from the myotomes in amniotes because it facilitates the development and evolution of motor systems in which anatomically and functionally different muscles have spatially separate motor pools in the cord.
