High-resolution views of these [alpha]-actinin-positive cells within these cultures indicated that this sarcomeric protein was exhibited in a nonstriated
pattern (Figure 4(c)).
The avian iris musculature is composed mainly of striated muscle fibers with variable amounts of nonstriated
muscle fibers (myoepithelium and/or smooth muscle).
Tubular molds with impressions of internal striations and nodes were determined to represent horsetails (Equisetum), whereas nonstriated
impressions may include rush (Juncus) and bulrushes (Scirpus).
Each perradial muscle bundle is comprised of nonstriated
muscle fibers that splay out at its terminus below the nerve ring (Fig.
(11,20) It has been suggested that a nonvascular nasal leiomyoma might represent a late evolutionary stage in the progression of the lesion from a vascular hemangioma, to an angioma with much nonstriated
muscle, to a leiomyoma with many vessels, and finally to a solid leiomyoma.
The gut is relatively thick, long, straight, and nonstriated
. PDL and PAL remain in the ranges of 70-75% and 71-76% BL, respectively (except for the 17.0-mm larva, which had a PDL and PAL of 62% BL).
