Document Summary

Tract: way we get info from one part of the cns to another (bundle of axons in the cns) Nerves go from cns to pns (bundle of axons in. Astrocytes: star shaped, most abundant, help anchor neurons close to capillaries. Roles in nutrient exchange, antigen presentation, control of neuron environment. Microglia: protective, touch neurons to monitor well being, transform into macrophages when needed, can move around. Ependymal cells: squamous, columnar, many ciliated; line cavities of brain and spinal cord as barrier, between csf and uid bathing cells of cns; cilia circulate. Oligodendrocytes: few branches ; provide myelin sheaths to cns neurons. Satellite cells: surround neuron cell bodies in ganglia-in uence chemical environment of these neurons, cell body. Schwann cells: form myelin sheaths around larger neurons in pns, vital to peripheral nerve cell regeneration, axon. Multipolar: 3+ processes arising from soma-most common type and major type in cns.
