The pseudopodia are pushed forward in the direction which the animal is to go, the rest of the body following.
The pseudopodia radiating from the latter pierce the calymma, form the sarcodictyum at its surface, and radiate from its nodal points freely into the surrounding water.
The piercing pseudopodia radiate everywhere between the spines, and are very numerous and thin.
Since, however, only a few species of this great legion have been observed in a living state, their pseudopodia require further accurate examination.
Specially modified pseudopodia and axial threads in particular do not seem to occur in this legion.
Also the characteristic motion of granules in the pseudopodia is very different.
They perform the latter action, however, when they fall accidentally upon a firm basis or are accidentally placed upon it, but they seem normally always to float freely in the water with pseudopodia radiating in all directions.
Perhaps it is always connected with the central nucleus by intracapsular axial fibres, and is to be regarded as a specially differentiated bundle of pseudopodia (or axopodia?
These projections, which are presently drawn in again, are called pseudopodia or false feet.
The Foraminifera are sometimes named Reticularia, because their pseudopodia interlace.
The pseudopodia emerge from the body between this membrane and the shell margin.
Pseudopodia are long, thin, and thread-form, with rounded ends.
Diameter 25 to 80ยต; pseudopodia twice as long as the body diameter; the plasm often contains chlorophyll bodies (Zoochlorella).
The short pseudopodiawhich give to the periphery a fringed appearance are quite regularly placed in connection with the pseudopodia.
A delicate layer of ectoplasm surrounds the granular endoplasm, and pseudopodia formation is eruptive, beginning with the accumulation of ectoplasm.
The protoplasm becomes massed outside of the mouth-opening and from here a dense network of pseudopodia forms a trap for diatoms and smaller Protozoa.
The pseudopodia are occasionally withdrawn, and the flagellum is the sole means of locomotion.
The pseudopodia have axial filaments that can be traced to the periphery of the nucleus.
Pseudopodia short and finger-form, emerging from the edge of the mantle-opening and swaying slowly from side to side or quiescent.
The pseudopodia are lobose, sometimes absent, the body then progressing by a flowing movement; the body consists of ectoplasm and endoplasm, the latter being granular and internal, the former hyaline and external.
On the long thin plasma-threads orpseudopodia which stream out from the unicellular body of the radiolaria and thalamophora, thousands of fine particles move about, like promenaders in a street.
If they are killed and examined with the aid of the best methods of coloring, it is quite impossible to detect any structure in them; and this is also true of the pseudopodia of the mycetozoa and many other rhizopods.
A fine network of pseudopodia pierces the calymma, which fills up the shell-cavity.
The entire shell is enveloped by the calymma and surrounded by radiatingpseudopodia (drawn much too short).
Numerous long pseudopodia arise from the granular sarcomatrix, which the capsule surrounds, and pass through the pores of the siliceous shell.
Numerous pseudopodiaradiate from the supporting spines of the sagittal ring.
In the jelly-calymma, between the capsule and the alveole, numerous thin ramified pseudopodia are expanded.
Numerous yellow cells or xanthellae are scattered between the radial pseudopodia in the periphery.
Between the radiant pseudopodia very numerous small yellow cells (xanthellae), which are scattered everywhere.
On the surface of the alveolated jelly-sphere the pseudopodia form a dense radiating zone.
The big spherical central capsule; a, the large alveoles filling the central capsule and surrounding a central nucleus; f, the pseudopodia piercing the extracapsular calymma.
Between these radiate numerous pseudopodia (compare for the single parts, Pl.
The polygonal network of lines, in which the radiating pseudopodiaare symmetrically arranged, is partly visible.
As for the temporary prolongations or pseudopodia which the amoeba seems to make, they would be not so much given out by it as attracted from it by a kind of inhalation or suction of the surrounding medium.
Dujardin, working on living forms, and he referred them to his Rhizopoda, characterized by pseudopodia given off from the sarcode (protoplasm) as organs of prehension and locomotion.
Rhizopoda Filosa, and are included here to show the characteristic filose pseudopodia in contrast with the reticulate spread of the others.
The long pseudopodia reaching beyond the spicules are not lettered.
The membrane of the capsule is usually rather thick and double-contoured, and bears on the truncate basal pole a circular "porochora" or area porosa, through which the pseudopodia are protruded.
Commonly the siliceous threads of the arachnoidal wickerwork are very thin, often extremely delicate, representing "pseudopodia metamorphosed into silex.
The pseudopodia arising from the central capsule form a loose network in the calymma, and proceed over its surface as numerous delicate radial filaments, often supported by the radial spines.
Very numerous radial pseudopodia arise everywhere from the sarcomatrix and run to the surface of the calymma, usually forming a rich network in it by means of numerous branches and anastomoses (compare Pl.
Between these the network of the anastomosing pseudopodia is expanded.
I there figured a complete living specimen with expanded pseudopodia and a double central capsule (in the stage of self-division).
The pseudopodiaare protruded from the central capsule through the porochora only.
The numerous pseudopodia are commonly branched, with rather rare anastomoses.
He gave the first description and figures of the central capsule of this group, with the characteristic lobes developed from its basal part; and of the pseudopodia radiating on all sides (loc.
The pseudopodiaarising from this peculiar "podoconus" proceed from the capsule piercing the "porochora," whilst the other parts of the capsule are not perforated.
An extensive division of rhizopods in which the pseudopodia are more or less slender and coalesce at certain points, forming irregular meshes.
It increases in size rapidly, gradually draws in its pseudopodia (the rays of the star) and makes its way through the ectoderm to the exterior.
One of these cells, the future egg, grows more rapidly than the others, some or all of which it finally absorbs by means of lobose pseudopodia extruded from its margin.
The positions of the protoplasm which the vesicles fashion change continually; only the grainless protoplasm of the pseudopodia develops no air.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "pseudopodia" in a variety of sentences. We hope that you will now be able to make sentences using this word.
