Tuft
Definition:
(n.) A collection of small, flexible, or soft things in a knot or bunch; a waving or bending and spreading cluster; as, a tuft of flowers or feathers.
(n.) A cluster; a clump; as, a tuft of plants.

(v. i.) To grow in, or form, a tuft or tufts.
Example Sentences:

(4) Approximately one-fourth of the cells contained cytoplasmic fibrillar bodies and amorphous fibrous tufts around the nuclear envelope.
(5) Stereociliary tufts in the tectorial region differ from those in the free-standing region in several ways.
(6) Severe mesangial insudation of material containing fibrinogen derivatives resulted in segmental tuft necrosis with almost complete replacement and destruction of the mesangial matrix.
(7) The anaxonic granule cell of the olfactory bulb is believed to inhibit mitral and tufted cells through reciprocal dendrodendritic synapses.
(8) Detached ciliary tufts (DCTs) have been observed in sputum, in cervicovaginal smears and, rarely, in fluid from the pouch of Douglas.
