| Name: | 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. |
