Term:	dendritic spine
Synonyms:	branched dendritic spine | dendrite spine | mushroom dendritic spine | sessile dendritic spine | stubby dendritic spine | thin dendritic spine
Definition:	A small, membranous protrusion from a dendrite that forms a postsynaptic compartment, typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable:they can be thin, stubby, mushroom, or branched, with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity.
