What are the 3 functions of astrocytes?
Functions of astrocytes include physical and metabolic support for neurons, detoxification, guidance during migration, regulation of energy metabolism, electrical insulation (for unmyelinated axons), transport of blood-borne material to the neuron, and reaction to injury.
What are astrocytes and why are they so important?
They have a regulatory role of brain functions that are implicated in neurogenesis and synaptogenesis, controlling blood–brain barrier permeability and maintaining extracellular homeostasis. Mature astrocytes also express some genes enriched in cell progenitors, suggesting they can retain proliferative potential.

What are the functions of astrocytes and microglia?
Each of the populations of non-neuronal cells of the adult CNS are remarkably adapted to support neuronal function: astrocytes maintain ionic and neurotransmitter homeostasis, refine synaptic connections, and provide neuronal metabolic substrates; microglia monitor synaptic elements and networks, responding to …
What is the function of dendrites in the neurons?
Most neurons have multiple dendrites, which extend out-ward from the cell body and are specialized to receive chemical signals from the axon termini of other neurons. Dendrites convert these signals into small electric impulses and transmit them inward, in the direction of the cell body.
What is the function of the dendrites of a neuron quizlet?
The dendrites conduct impulses toward the cell body, through the cell body, and onto the axon away from the body.
What is the main function of axon?
The function of the axon is to transmit information to different neurons, muscles, and glands.
