Where can you find bipolar neurons? Retina of the eye, olfactory region, and inner ear Where can you find unipolar neurons? Most sensory Where can you find multipolar neurons? Most CNS and efferent neurons Neuroglia of the CNS -astrocytes (blood-brain barrier) -microglial cells -ependymal cells -oligodendrocyte Neuroglia of the PNS -Schwann cells -satellite cells Olfactory nerve (CNI) 1- Smell Optic nerve (CNII) 2- visual

Neuroglia support, insulate and protect the neurons Astrocytes compose half of all nervous tissue. Star shaped; Cling to neurons and bring them blood supply Microglia spider-like phagocytes that dispose of cellular debris and bacteria Ependymal Cells line the CNS cavities. Contain cilia that move CSF around. Oligodendrocytes produce the fatty coverings around neurons called myelin sheaths, that insulate the neurons. Schwann Cells form myelin sheaths arou...
