fasciculus

 [fah-sik´u-lus] (pl. fasci´culi) (L.)
a small bundle or tract, especially of nerve or muscle fibers. Called also fascicle.
cuneate fasciculus of medulla oblongata the continuation into the medulla oblongata of the cuneate fasciculus of spinal cord.
cuneate fasciculus of spinal cord the lateral portion of the dorsal funiculus of the spinal cord, composed of ascending fibers that end in the nucleus cuneatus.
gracile fasciculus of medulla oblongata the continuation into the medulla oblongata of the gracile fasciculus of spinal cord.
gracile fasciculus of spinal cord the median portion of the dorsal funiculus of the spinal cord, composed of ascending fibers that end in the nucleus gracilis.

Plural of fasciculus.

fasciculus

[fəsik′yələs] pl. fasciculi
Etymology: L, little bundle
a small bundle of muscle, tendon, or nerve fibers wrapped by a layer of connective tissue called the perimysium (muscle) or perineurium (nerve fiber). The arrangement of fasciculi in a muscle is correlated with the power of the muscle and its range of motion. The patterns of muscular fasciculi are penniform, bipenniform, multipenniform, and radiated. Also called fascicle. fascicular, adj.

This arrangement resulted in the appearance of distinct clusters of similarly oriented acicular crystals termed fasciculi, visible at the skeletal surface (Fig.
Bundles of acicular crystals that form fasciculi at the septal surface can not be visualized.
Also found on septa were clusters of acicular crystals forming fasciculi, fusiform crystals, and a novel lamellar type of crystal.
The surface of coral skeleton is frequently characterized by groups of nearly parallel acicular crystals termed fasciculi (Wise, 1972).
Hidaka (1991b) also recognised this paradox and suggested that fasciculi may form in several different ways.
Microscopically, round and polygonal muscle fibers of several diameters were observed, and altered muscle fibers with a central nucleus, degenerating fibers and macrophages were noted in more deeply fasciculi.
The masseter muscle of control animals showed polygonal muscle fibers comprising fasciculi in the superficial region of the muscle (Fig.
In the malocclusion group, the masseter muscle on the right side showed polygonal and round muscle fibers present in the fasciculi of the superficial region.
Microscopic analysis yielded the following findings: 1) both in the malocclusion and control groups, the two posterior thirds of the masseter muscle consist of altemating muscle bundles and thick septae of connective tissue; 2) in the control group, a similar arrangement of polygonal muscle fibers in the fasciculi of superficial region was observed on the right and left side and; 3) in the malocclusion group, a large amount of morphologically altered fibers of variable diameters were observed in the deep bundle on the ipsilateral side, with these changes being more discrete on the contralateral side, while the superficial bundle presented characteristics similar to the control group.
