| NG tube | Naso-Gastric tube |
|---|---|
| PE tube | Polyethylene Ventilating tube placed in the eardrum |
| SB tube | Sengstaken-Blakemore tube |
| ET | educational therapy; effective temperature; ejection time; embryo transfer; endothelin; endotoxin; e... |
| OET | oral endotracheal tube; oral esophageal tube |
| primary embryonic cell | In a very young embryo, a cell still capable of differentiation. (05 Mar 2000) |
|---|---|
| embryonic | Undeveloped, related to the embryo. (16 Dec 1997) |
| embryonic axis | The cephalocaudal axis established in the embryo by the primitive streak. (05 Mar 2000) |
| embryonic blastoderm | That part of the blastoderm that takes part in the formation of the embryonic body. (05 Mar 2000) |
| embryonic cataract | A congenital cataract situated near the anterior Y suture of the foetal lens nucleus. (05 Mar 2000) |
| embryonic cell | One of the cells produced as the result of cell division, cleavage, in the fertilized egg. (18 Nov 1997) |
| embryonic circulation | The basic plan of the circulation of a young mammalian embryo, at first similar to that in aquatic forms, with an unpartitioned heart and conspicuous aortic arches in the branchial region; as gestation progresses, the arrangement of the major blood vessels gradually approaches that of an adult, but the routing of blood through the heart, characteristic of an adult, cannot be attained until lung breathing begins at birth. (05 Mar 2000) |
| embryonic disk | Germ disk, the point in a telolecithal ovum where the embryo begins to be formed. Synonym: embryonic disk, germinal area, area germinativa. (05 Mar 2000) |
| embryonic haemoglobin | See: haemoglobin Gower-1, haemoglobin Gower-2. (05 Mar 2000) |
| embryonic induction | The induction of differentiation in one tissue as a result of proximity to another tissue arising, for example: during gastrulation. One of the best known examples is the induction of the neural tube in the ectoderm by the underlying chordo mesoderm. Although the information to form the tube is present in the competent determined ectoderm, it must be elicited by the inducing tissue. In some cases it is known that cell cell contact between epithelium and mesenchyme is necessary. (18 Nov 1997) |
| embryonic membrane | A structure or tissue that develops from the fertilised ovum but does not form part of the embryo proper. Synonym: embryonic membrane, extraembryonic membrane. (05 Mar 2000) |
| embryonic shield | A thickened area of the embryonic blastoderm from which the embryo develops. (05 Mar 2000) |
| embryonic structures | The anatomical features of the animal embryo deriving from the fertilised ovum, that eventually become the offspring. (12 Dec 1998) |
| fibroblast growth factor receptor-like embryonic kinase | <enzyme> Found in avian embryonic tissue; involved in early differentiation of skeletal muscle. Registry number: EC 2.7.1.- Synonym: frek (26 Jun 1999) |
| Abbott's tube | A tube with two lumens, one ending in a small collapsible balloon and the other in a metallic tip with numerous perforations; used for intestinal decompression. Synonym: Abbott's tube. (05 Mar 2000) |
