What's the difference between embryonic and parachordal?
Embryonic
Definition:
(a.) Of or pertaining to an embryo; embryonal; rudimentary.
Example Sentences:
(1) Brain and ganglia of embryonic Periplaneta americana were grown for 2 to 3 weeks in a chemically defined medium.
(2) It was found that the skeletal muscle enzyme of the chick embryo is independent of the presence of creatine and consequently is another constitutive enzyme like the creatine kinase of the early embryonic chick heart.
(3) Right orchiectomy and retroperitoneal lymph node dissection for embryonal carcinoma had been performed 5 years earlier.
(4) Blocks of hippocampal tissue containing the fascia dentata were taken from late embryonic and newborn rats and transplanted to the hippocampal region of other newborn and young adult rats.
(5) In conclusion, autoimmune thyroiditis in an animal model can be prevented by reducing thyroidal iodine or its metabolism and optimal effects require intervention at the embryonic stage.
(6) On embryonic day 3.5 (E3.5), 1 day after surgery, there is a 42% average increase in volume of the polyganglia compared with the corresponding DRG on the unoperated side.
(7) Isoenzyme LDH4 was absent in the human pancreas in all the studied periods of embryonic development.
(8) The mRNA data of the developing gut correspond with previous protein data, which showed that the shorter Mr 210,000 polypeptide predominates during earlier developmental stages and the larger Mr 260,000 polypeptide appears later in the embryonic gut (Aufderheide, E., and P. Ekblom.
(9) Almost nothing is known about nature and timing of the embryonic cues which induce or initiate spicule formation by these cells.
(10) Implantation is dependent on embryonic age and is independent of endometrial maturation within this window.
(11) The junctional currents were already constant 1 ms after step changes in the junctional voltage; this was three orders of magnitude faster than the other known examples of voltage-controlled gap junctions between embryonic cells.
(12) Zona pellucida solubility, plasminogen activator production, and plasminogen conversion to plasmin increased as embryonic stage advanced; however, plasminogen activator production and plasmin conversion to plasmin were poorly correlated with zona pellucida solubility.
(13) He fashioned alliances with France in the 1950s, and planted the seeds for Israel’s embryonic electronics and aircraft industries.
(14) Both kinds of experiments show that 1, 25-(OH)2D3 has effects on embryonic bone which are typical for high concentrations of parathyroid hormone (PTH).
(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.
(17) Embryonal carcinomas were found in 15 tumours, two being of pure type and the remaining 13 a part of mixed tumours.
(18) A large portion of the N-terminal globule of human collagen VI was prepared from the culture medium of stably transfected human embryonic kidney cell clones.
(19) The tissues were derived from the three germ layers and were prevalently mature; only a bit of them was represented by embryonic mesenchymal tissue.
(20) Phosphotyrosine-modified proteins were also abundant in and highly restricted to the process-rich layers of the embryonic optic tectum.
Parachordal
Definition:
(a.) Situated on either side of the notochord; -- applied especially to the cartilaginous rudiments of the skull on each side of the anterior part of the notochord.
(n.) A parachordal cartilage.
Example Sentences:
(1) The Processus recessus can be regarded as a part of the parachordal plate that was shifted laterally together with the Recessus scalae tympani by the enlargement of the cochlear part of the otic capsule in the ancestors of living mammals.
(2) As a result, the possible and probable sources of the cranial and spinal meninges are believed to be: (a) prechordal plate, (b) unsegmented paraxial (parachordal) mesoderm, (c) segmented paraxial (somitic) mesoderm, (d) mesectoderm (neural crest), (e) neurilemmal cells (neural crest), and (f) neural tube.
(3) The occipitocervical region settles down around the rostral extremity of the chorda, from components coming from the parachordal cartilage, the occipital somites and the first cervical somites.
(4) D. Stresses resulting from paired otic capsules of unequal size bent the parasphenoid bone and the parachordal cartilage through angles of predictable direction relative to the notochord.
(5) The parietal and squamosal bones, and possibly the parasphenoid bone and parachordal cartilage apparently used the capsule as a substrate, spreading over its surface.
(6) On the 28th d of ontogeny (the gestation period of Tupaia belangeri is 43 d), it is fused with the lateral edge of the parachordal plate.
