Thus in many mammals the mesodermal part of the allantois often appears long before the endodermal part, though this is phylogenetically older.
This Keibel ascribes to the fact that the endodermal part is almost functionless.
The walls here are at first only a few score of feet in height, but increase rapidly to almost 5000 ft.
Rivers, see Index to Reports of the Chief of Engineers, United States Army (3 vols.
Their ectodermal muscles are mainly longitudinal, their endodermal muscles are circularly arranged on the body-wall.
The medusoids have no true velum; in some cases a structure more or less resembling this organ, termed a velarium, is present, permeated by endodermal canals.
In contrast with the polyp, the longitudinal muscle-system is entirely ectodermal, there being no endodermal muscles in craspedote medusae.
Amphioxus at a certain stage of development; as a fourth variety of endodermal cells excretory cells should perhaps be reckoned, as seen in the pores in the foot of Hydra and elsewhere (cf.
There is, however, no evidence whatever for this, the gonads of Hydra being purely ectodermal structures, while all medusoid gonophores have anendodermal portion.
Both these medusae have sense-organs of a peculiar type, which are said to contain an endodermal axis like the sense-organs of Trachylinae, but the fact has recently been called in question for Limnocodium by S.
The gonads (g) are produced on the manubrium, which has a hollow endodermal axis, termed the spadix (sp.
Each cordylus is a tentacle-like structure with an endodermal axis containing an axial cavity which may be continuous with the ring-canal, or may be partially occluded.
The endodermal spadix (sp) of the sporosac represents the endoderm of the manubrium; the ectodermal lining of the sporosac (ex.
The development, on the contrary, shows unequivocally that the endoderm-lamella arises as a local coalescence of the endodermal linings of a primitively extensive gastral space.
An endodermal axis is continued through the whole structure, and in one or more of the endoderm cells of the club-shaped body otoliths are always present.
They have a swollen extremity, and are provided with an endodermal axis for half the length of which there is a diverticulum of the gastrovascular canal system.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "endodermal" in a variety of sentences. We hope that you will now be able to make sentences using this word.
