0 one part of a book that is published or made available separately:
1 a group of muscle or nerve fibres:
muscle fascicles
axonal fascicles
the medial longitudinal fasciculus
The volume is made of a series of fascicles, each of which begins with a new document.
I take my pen-knife and slit the whole book up into forty or so fascicles.
A section of the original text is missing: apparently one or two fascicules.
The left bundle branch divides into two or three sheet-like fascicles that spread over the left ventricular subendocardial surface.
These areas are connected by a bundle of axons known as the arcuate fasciculus.
In the central nervous system the nerve fibres are organized in bundles called tracts, or fasciculi.
Each fascicle is subdivided into smaller fascicles of axons arranged around a group of glial cells with large nuclei.
The intrinsic tectal astrocytes closely associated with fascicles of vimentin labeled radial glial cells, indicating a presumptive radial migration of astrocytes.
