astrocyte
(noun)
a neuroglial cell, in the shape of a star, in the brain
Examples of astrocyte in the following topics:
-
Glia
- Astrocytes make contact with both capillaries and neurons in the CNS .
- Astrocytes also form the blood-brain barrier: a structure that blocks entrance of toxic substances into the brain.
- Glial cells of the (a) central nervous system include oligodendrocytes, astrocytes, ependymal cells, and microglial cells.
- Astrocytes provide nutrients to neurons, maintain their extracellular environment, and provide structural support.
- (a) Astrocytes and (b) oligodendrocytes are glial cells of the central nervous system.
-
Muscle Tissues and Nervous Tissues
- Astrocytes regulate the chemical environment of the nerve cell, while oligodendrocytes insulate the axon so the electrical nerve impulse is transferred more efficiently.
- Also shown are two types of glial cells: astrocytes to regulate the chemical environment of the nerve cell, and oligodendrocytes to insulate the axon so the electrical nerve impulse is transferred more efficiently.
-
Synaptic Transmission
- First, reuptake by astrocytes or presynaptic terminal where the neurotransmitter is stored or destroyed by enzymes.
