What is the Meaning of Dendritic Spines?

Dendritic spines are small, membranous protrusions that extend from the dendrites of neurons, serving as the primary postsynaptic sites for excitatory synaptic input. These mushroom-shaped structures are fundamental to synaptic plasticity, memory formation, and learning, representing the physical substrate of neural communication. Their density and morphology are highly dynamic and profoundly influenced by circulating neuroactive hormones.

What is the Origin of Dendritic Spines?

The name is purely descriptive, combining 'dendritic,' referring to the neuron's branching extension, with 'spines,' describing their thorn-like appearance. This anatomical term emphasizes their small, specialized structure on the neuronal surface.

What is the Mechanism of Dendritic Spines?

The structural remodeling of dendritic spines is powerfully regulated by neurosteroids and sex hormones, including estrogen and progesterone, which exert rapid, non-genomic effects on neuronal membranes. These hormones modulate the actin cytoskeleton within the spine head, leading to changes in spine shape and size, which directly correlates with synaptic strength. This hormonal influence highlights a critical link between endocrine status and cognitive health, particularly in areas like the hippocampus.
