Nervous system
Mylan sheets wraparound what of a neuron to provide protection and installation
Axon
microglial cells
Defend
Schwann cells
Form myelin sheaths around PN fibers Regeneration of damaged nerves
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
Oligodendrocytes
Wrap and insulate , form myelin sheath
What is the name of the glial cells that act as phagocytes to aid in protecting CNS neurons
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 )
Retrograde
toward cell body (ex:organelles to be degraded/recycled)
