Zona was guide and chief of the party; he knew the land well, and he knew the river.
Zona shrugs his square thin shoulders, and Kenneth and Archie laugh.
Zona used to retire to the bush, and it is but fair to say that, according to his lights, he was as good at heart as any of the others.
Zona brought with him a bold but honest-looking black boy.
The layer of cells lining the interior of the vesicle next to the zona pellucida forms Rauber's "Deckschichte" or prochorion.
The zona pellucida appears thickened, and contains many spermatozoa which failed to penetrate the ovum.
Situated around the vitellus, or between the vitellus and zona pellucida of an ovum.
Situated under a zone, or zona; -- applied to a membrane between the zona radiata and the umbilical vesicle in the mammal embryo.
It is liable to affect the hands, and to return at distant periods; and is probably a secondary disease, as well as the zona ignea, or shingles, described below.
Defn: Situated under a zone, or zona; -- applied to a membrane between the zona radiata and the umbilical vesicle in the mammal embryo.
Defn: Situated around the vitellus, or between the vitellus andzona pellucida of an ovum.
Pyriform bodies surrounding the zona radiata of the ovum, probably the remains of epithelial cells.
Will did not enter with Senor Sarasta into the house, but went straight to the stables with the vaqueros and saw his horse and Zona cared for.
I do not like to think of the last part of it; we were both worn out, Zona and I, and if we had not come down upon the river we should have both died.
However, it is not as a poet, but rather as a short story writer that we are remembering Zona Gale.
Zona Gale remembers much of the play life and the school life in her home town during the eighties and early nineties of the last century.
Stories must happen somewhere, and the capital of Zona Gale's character world is "Friendship Village.
The result was persistent smuggling, extensive emigration from the southern to the northern bank, and the commercial decline of the frontier states of Mexico, till the Zona Libre adjusted the commercial discrepancy.
It is important for here begins the cultivated zone which extends as far as the Andes and which is known as the Zona del Riego.
The country at the foot of the Andes near the latitudinal center of Argentina which is watered by the mountain streams is called the Zona del Riego.
The ovum when laid is usually invested in the zona radiata only, though a vitelline membrane is sometimes present in addition, e.
It is still invested by the zona radiata, and in the rabbit an albuminous envelope is formed around it in its passage downwards.
It soon fuses with the zona radiata, or at any rate the zona ceases to be distinguishable.
We may commence with a blastodermic vesicle, closely invested by the delicate remnant of the zona radiata, at the stage in which the medullary groove is already established.
In the region of each swelling the zona around the blastodermic vesicle is closely embraced, in a ring-like fashion, by the epithelium of the uterine wall.
Impregnation is external, and on its occurrence a contraction of the vitellus takes place, so that a space is formed between the vitellus and the zona radiata, which becomes filled with fluid.
The nature of these processes requires further elucidation, but in some instances they appear to proceed from the zona (the Rabbit) and in other instances from the subzonal membrane (the Dog).
The ovum, enclosed by the zona radiata, passes into the Fallopian tube and undergoes a segmentation which has not been studied with great detail.
It is enclosed by a membrane formed from thezona radiata and the mucous layer around it.
The egg still lies freely in the uterus, and is invested by its zona radiata.
The ovum is, the reader will remember, first surrounded by the transparent structureless ovolemma or zona pellucida (Figures 1.
The human ovum possesses all the distinctive features of the ovum of the viviparous mammals, especially the characteristic formation of its membrane (zona pellucida), which clearly distinguishes it from the ovum of all other animals.
The globular yelk is surrounded by the thick transparent germinal membrane (ovolemma, or zona pellucida).
The little globule is surrounded by a thick capsule of glass-like transparency, the zona pellucida, or ovolemma pellucidum (Figure 1.
As a fact, all the embryonic peculiarities that distinguish the mammals from other animals are found also in man; even the ovum with its distinctive membrane (zona pellucida, Figure 1.
The thick, outer, structureless envelope that encloses it is the original ovolemma or zona pellucida, modified, and clothed with a layer of albumin that has been deposited on the outside.
In birds both vitelline membrane andzona radiata are present, but the latter atrophies early, leaving the former as the sole membrane when the egg is ripe.
The formation of the zona radiata has been studied by Selenka.
The zona radiata attains a very great development, and is generally provided with knobs of various shapes on its outer surface.
In both Phascolosoma and Sipunculus a vitelline membrane with radial pores--zona radiata--is formed, and in Phascolosoma the external part of this is separated off as a structureless vitelline membrane.
The term zona radiata will be applied to perforated membranes of this kind.
Within the zona radiata a third and delicate membrane is occasionally found, especially when the ovum is approaching maturity.
Externally to the zona radiata there may be observed a granular membrane irregular on its outer surface on which the cells of the discus are supported.
The vitelline membrane also gradually atrophies, though it lasts much longer than the zona radiata.
In the ripe ovum of the Herring there is a distinctly developed membrane external to the zona radiata which is probably the vitelline membrane.
As became a young captain of contrabandistas who longed to prove that he deserved to wear his spurs, his time had been passed for the most part in making handsome dashes from the Zona Libre into the interior.
They have around them a dark contour line, which I can only interpret as the commencement of the membrane (zona radiata?
Osseous fish have almost always a zona radiata, which it seems best to assume to be equivalent to that in Elasmobranchii.
Internal to this is a thin membrane, the equivalent, according to Eimer, of the membrane found by the same author within the zonain Reptilia.
The inner one is the zona radiata with a typical radiately striated structure.
A special internal differentiation of the zona radiata is apparently found (Eimer) in many Reptilia.
In Amphibia the single late formed and radiately striated (Waldeyer) membrane would appear to be a zona radiata.
Of these the inner one, or zona radiata, will probably be admitted on all hands to be a product of the peripheral protoplasm of the egg.
In Petromyzon, a zona radiata appears to be present[420], which is divided in the adult into two layers, both of them perforated.
The zona becomes marked off from the yolk, and its radial striae become easy to see even with comparatively low powers.
The first formed membrane, whether or no it becomes the zona radiata, is very similar to the vitelline membrane of Elasmobranchii and arises at a corresponding stage.
Foulis regards the zona pellucida as a product of the ovum and not of the follicle.
The zona radiata has been made rather too thick by the artist.
Both the vitelline membrane and the zona radiata are found in Raja, but in a much less developed condition than in Scyllium.
From this stage onwards, both vitelline membrane andzona gradually atrophy, simultaneously with a series of remarkable changes which take place in the follicular epithelium.
Most superficially is the zona glomerulosa, then the zona fascicularis, and most deeply the zona reticularis.
