What is the function of myelin sheath

Increase speed of nerve impulse, protect an electrically insulate axon

Schwann cells

Insulate , help form myelin sheath

ependymal cells

Line cavities

Neurons (nerve cells)

Long lived, Amitotic, High metabolic rate, plasma membrane functions in electrical signal

The axons of some neurons in the CNS are protected by glial cells that for Myelin sheath around axons. These glial cells are called?

Oligodendrocytes

glial cells

Provide support, nutrition, insulation, help with transmission in the nervous system

ependymal cells

Squamous to columnar, May be ciliated, Line central cavities of brain and spinal column, moves cerebral spinal fluid in the cavities

Astrocytes

Support, regulate ions

sattelite cells

Surround Neuron cell bodies in PNS

microglia

Schwann cells

produce myelin in PNS

Microglia

small, ovoid cells with spiny processes Phagocytes that monitor the health of neurons

Satellite cells (PNS)

surround neuron cell bodies in PNS

The axon

the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands

Anterograde

toward axonal terminal(ex: mitochondria proteins )
