A skeletal muscle refers to multiple bundles (fascicles) of cells joined together called muscle fibers. The fascicles of nerve fibers in the PNS (homologous to CNS tracts) are called nerves. The collagen fibers are parallel to each other and organized into fascicles. The left bundle branch further divides into the left anterior and the left posterior fascicles. It usually surrounds multiple nerve fascicles as well as blood vessels which supply the nerve. On each foot, the five clearly distinguished toes are grouped into two fascicles. The southwestern subspecies has , stout needles in fascicles of three (averaging ). The left bundle branch has two fascicles. Oracle bone inscriptions were published as they were discovered, in fascicles. The collection contains some 22,000 volumes, 700 fascicles, and a number of manuscripts. The forty fascicles she created from 1858 through 1865 eventually held nearly eight hundred poems. Currently some two dozen fascicles of the "Corpus Speculorum Etruscorum" have been published.
