Neuron-Glia Interaction

Flashcards focusing on vocabulary related to neuron-glia interactions, covering key concepts, cells, and processes involved in neuroscience.

Glial Functions

The roles and activities of glial cells, including promoting neuron survival, guiding axon growth, and facilitating synapse formation.

Oligodendrocytes

Glial cells in the central nervous system responsible for myelinating axons.

Astrocytes

Star-shaped glial cells that support neurons and participate in neurotransmitter regulation.

Myelination

The process of forming a myelin sheath around the axons of neurons to improve signal transmission speed.

Tripartite Synapse

A synaptic model that includes the presynaptic neuron, postsynaptic neuron, and surrounding astrocytic processes, which modulate synaptic transmission.

Brain-Blood Barrier

A selective permeability barrier formed by tight junctions between endothelial cells in the brain, protecting the brain from harmful substances.

Glial Growth Factor (GGF)

A factor that influences the differentiation of neural crest cells into glial cells, particularly Schwann cells.

Platelet-derived growth factor (PDGF)

A growth factor crucial for the development and differentiation of oligodendrocytes in the central nervous system.

Cajal-Retzius cells (CR)

A type of glial cell involved in radial glial cell development and guiding neural migration during development.

Neuregulin

A protein that plays a significant role in the proliferation and survival of Schwann cells and the interaction with axons.

Intermediate progenitor cells (IPC)

Cells derived from radial glial cells during neurogenesis that contribute to the formation of neurons and glial cells.
