Astrocytes: Anatomy, Location, and Function - Verywell Health Astrocytes are star-shaped cells found in the brain. Similarly to other neuronal cells, astrocytes are comprised of synapses, or cell ends that allow for chemical and electrical communication between cells. Astrocytes also consist of dendrites that allow for communications from other cells to be transmitted within the cell body of the astrocyte.

They are the most abundant glial cells present in brain. Astrocytes have two subtypes and are performing a number of functions. In the article, we will review different aspects related to astrocytes. Structure As the name suggests, astrocytes are star-shaped cells.

Which of the following is not a function of astrocytes? The astrocytes are an abundant macroglial cell that occurs throughout the brain and spinal cord. This type of neuroglia seems to help guide the axonal development of neurons. They also occur near to the blood vessels of the brain and are thought thus to play an important role in the exchange of materials between neurons and blood capillaries.

Astrocytes quiz Flashcards | Quizlet Astrocytes play an important role in synaptic transmission. Astrocytes have the same NT receptors as the postsynaptic terminal, and when these receptors on the astrocytes are active it increases intracellular calcium and releasing gliotransmitters. What are gliotransmitters? NT's that can be only released from astrocytes Astrocyte - Wikipedia Astrocytes are a sub-type of glial cells in the central nervous system. They are also known as astrocytic glial cells. Star-shaped, their many processes envelop synapses made by neurons. In humans, a single astrocyte cell can interact with up to 2 million synapses at a time.
