Sorry, no etymologies found.
The cells which it encloses are possessed of ameboid movement.
Large rounded cells, termed splenic cells, are also seen; these are capable of ameboid movement, and often contain pigment and red-blood corpuscles in their interior.
By means of these ameboid properties the cells have the power of wandering or emigrating from the bloodvessels by penetrating their walls and thus finding their way into the extravascular spaces.
They can be further recognized by their irregular form and ameboid processes, and by the fact that their cytoplasm has no affinity for ordinary stains, but assumes a brownish tinge when treated by osmic acid.
In an ameboid cell, there is a framework of spongioplasm, which stains with hematoxylin and similar reagents, enclosing in its meshes a clear substance, hyaloplasm, which will not stain with these reagents.
Blood platelets possess the power of ameboid movement.
These marrow cells proper, or myelocytes, resemble in appearance lymphoid corpuscles, and like them are ameboid; they generally have a hyaline protoplasm, though some show granules either oxyphil or basophil in reaction.
If this view be true, it is a matter of great interest, and, as Schäfer has shown, harmonizes the contraction of muscle with the ameboid action of protoplasm.
Leucocytes are defined to be "minute, nucleated, colorless masses of protoplasm, capable of ameboid movements, found swimming freely in blood and lymph, in the reticulum of lymphatic glands, and in bone-marrow and other connective tissue."
It is well known that the moment the leucocytes are submitted to an alcoholic solution, their ameboid movements cease, and their function is arrested.
