What's the difference between somatopleure and vertebrate?
Somatopleure
Definition:
(n.) The outer, or parietal, one of the two lamellae into which the vertebrate blastoderm divides on either side of the notochord, and from which the walls of the body and the amnion are developed. See Splanchnopleure.

(13) Thus, avian extra-embryonic somatopleure, both ectoderm and mesoderm, possesses the information for feather development: the extra-embryonic ectoderm, if it is brought in contace with an appendage-forming dermis, is able to respond to the dermal induction by initiating feather morphogenesis; the extra-embryonic mesoderm, if it is experimentally transformed into a dense dermis, can express its feather-forming capacity by specifying feather tract morphology and barb-ridge number, thus leading to the acievement of feather morphogenesis.
(14) Labeling in the ten tissues indicated (1) a tissue-specific spectrum of incorporation of [3H]thymidine, (2) close correlation between frequency and intensity of labeling within a tissue and (3) asymmetrical quantities of incorporation between right and left somatopleure.
(15) In quail embryos of day 2-5, Quox-7 transcripts were found essentially in the ventral mesenchyme (neural crest-derived mesectoderm of the face and hypobranchial structures, somatopleure, and limbs) and also in a narrow dorsomedial band of cells of the superficial ectoderm and neural tube.
(16) Quail-to-chick grafting experiments were performed on 2-day embryos in order to test the differentiating abilities of the somatopleure.
(17) The skeletal musculature of chick limb buds is derived from somitic cells that migrate into the somatopleure of the future limb regions.
(18) We conclude that the somatopleure, and most likely its connective tissue component, contains the information for setting up a specific axon guidance system in the developing limb.
(19) As soon as the 14-somite stage, increased proliferative activities occurring in a limited area of the embryonic somatopleure close to the caudal end of the coelomic cavity point out the onset of limb morphogenesis.
(20) In early stage embryos, Msx-1 was expressed in the somatopleure.
Vertebrate
Definition:
(n.) One of the Vertebrata.
(a.) Alt. of Vertebrated
Example Sentences:
(1) Local embolism, vertebral distal-stump embolism, the dynamics of hemorrhagic infarction and embolus-in-transit are briefly described.
(2) An axillo-axillary bypass procedure was performed in a high-risk patient with innominate arterial stenosis who had repeated episodes of transient cerebral ischemia due to decreased blood flow through the right carotid artery and reversal of blood flow through the right vertebral artery.
(3) Two cases of posterior lumbar vertebral rim fracture and associated disc protrusion in adolescents are presented.
(4) The greatest advantages of spinal QCT for noninvasive bone mineral measurement lie in the high precision of the technique, the high sensitivity of the vertebral trabecular measurement site, and the potential for widespread application.
(5) With the successful culture of these tissues, their development, biochemistry, and physiology, potentially of great importance in understanding early vertebrate evolution, can be better understood.
(6) In this paper, we examine corticosteroid 11 beta-oxidation and 11-reduction as properties of the microsomal 11 beta-hydroxysteroid dehydrogenase complex in vertebrate livers.
(7) The bony elements of both adjacent vertebral bodies are secondarily involved.
