Etymology
From axo- + -plast.
Noun
axoplast (plural axoplasts)
- (biology) A dense structure, with no microtubules, located in the center or close to the nucleus of a cell, and from which radiate axopodia.
1991, Michael A. Sleigh, Protozoa and Other Protists, →ISBN, page 183:Centroaxoplastids have an axoplast at the centre of the cell, in a membrane-enclosed cavity within the nucleus, and radiating bundles of microtubules in a pin-wheel array (Fig. 6.13j), which is an extension of the cryptoaxoplastid pattern.
2012, O. Roger Anderson, Radiolaria, →ISBN, page 46:According to the distributional pattern of the axopodia and the location and form of their intracapsular organizing center, the axoplast, Hollande and Enjumet identified the following taxa: (1) the anaxoplastidies lacking a well-defined axoplast -- the radial axopodia arise in the central capsule cytoplasm from isolated ponts, sometimes near the papillae of the nuclear memberanel (2) the periaxoplastidies possessing a distinct axoplast occurring outside the nucleus either in a juxtanuclear position or in a concavity formed by the slight invagination of the nuclear envelope, or variously embedded within the fold-like center of a capiform nucleus; and (3) the centroaxoplastidies, exhibiting a centronuclear axoplast. In the latter group, the axoplast is surrounded by the nucleus.
2012, Pierre Dustin -, Microtubules, →ISBN, page 155:All axopodia appear to arise either from the nuclear membrane or from an axoplast.
2013, P.C. Reid, Carol Turley, P.H. Burkill, Protozoa and Their Role in Marine Processes, →ISBN, page 27:Large bundles of axopodia radiate from an axoplast granule at each smaller pore, and the large pore is said to act as a cytostome.
