Dendritic spines

Mushroom- or button-shaped protrusions on dendrites, at the tip of which there is usually a synapse, which is the site of communication between two nerve cells. The spines increase the surface area of dendrites, which thus have space for additional synapses. They play an important role in synaptic plasticity. The dendritic spines can swell and shrink depending on activation.
