nervous

• Neuroglia - are specialized nervous tissue cells, serve to carry out support functions such as vascularization, phagocytosis and myelinization.
• Astrocytes - star shaped with many processes, participate in the metabolism of neurotransmitters, maintain proper K+ balance, help form blood brain barrier
• Oligodendrocytes - fewer processes and are smaller that astrocytes, most common type in the CNS, they are involved in myelinization
• Microglia - small cells derived from monocytes that function as macrophages and carry out phagocytosis.
• Ependymal - columnar to squamous epithelial cells often ciliated that form a lining in the ventricles (fluid filled cavities in the brain
• neuron - the basic unit of nervous tissue. They are responsible for sensing stimuli and transmitting signals to and from different parts of an organism.
• cell body - contains the neuron's nucleus, associated cytoplasm and other organelles
• axons - transmits information and extends away from the soma or cell body. It typically carries signals away from the cell body, but occasionally receives impulses from axoaxonic connections
• Dendrites - are similar to axons, but tend to be multibranched extensions that typically carry signals toward the cell body. They generally receive neurochemical impulses from the axons of other cells
