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.
