A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. Protrusion from a dendrite. Spines are specialised subcellular compartments involved in the synaptic transmission. They are linked to the dendritic shaft by a restriction. Because of their bulb shape, they function as a biochemical and an electrical compartment. Spine remodeling is though to be involved in synaptic plasticity. A prolongation or process extending from a cell, e.g. a flagellum or axon. A small membranous protrusion, often ending in a bulbous head and attached to the neuron by a narrow stalk or neck. A spine that originates from the axon, usually from the initial segment.
