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.

fasciculus cuneatus of medulla oblongata
the continuation into the medulla oblongata of the fasciculus cuneatus of the spinal cord.
fasciculus cuneatus of spinal cord
the lateral portion of the dorsal funiculus of the spinal cord, composed of ascending fibers that end in the nucleus cuneatus.
