central nervous system nervous system consisting of brain and spinal cord
peripheral nervous system nervous system consisting of peripheral nerves
'glue' provide support for neurons, 5 type, 4 in CNS, 1
glia
in PNS
neurons nerve cells, transmission of information
dendrites recieve input, send info into cell body
cell body contains nucleus and organelles
carries electrical impulses, may/may not be
axon
myelinated
axon terminals end terminus of the axon, neuro transmitter release
tract bundle of axons in the CNS
grey matter group of cell bodies in cerebral cortex/spinal cord
white matter bundle of axons in cerebral cortex/spinal cord
ganglion group of cell bodies in PNS
nerve bundle of axons in PNS
dendrites and cell body, receives chemical signals
input zone
from other neurons
summation zone axon hillock, decides to transmit signal or not
, axon may be quite long, carry electrical signals
conduction zone between brain areas to and from spinal cord or to and
from peripheral sensory receptors
axon terminals, contact input of other neurons,
output zone
release of neuro transmitter
multiple processes emanate from the cell body, the
multipolar
'typical' neuron
2 processes emanate from the cell body (axon and
bipolar
long bridge to dendrites
1 process emanates from cell body (hangs on side of
unipolar
axon)
anaxonic no distinct axon, all processes look alike
supply nutrients to neuron, ensheath blood
astrocytes
capillaries, transmit information, CNS
immune cells of the CNS, engulf micro organisms /
microglia
debris
line fluid filled spaces of brain and spinal cord, have
ependymal cells
cillia to circulate CSF, CNS
oligodentrocytes support nerve fibres, ensheath them with myelin, CNS
support peripheral nerve fibres, ensheath them with
schwann cells
myelin, similar to oligodendrocytes, PNS
lipid wrapped around axon, increases conduction
velocity, multiple schwann cells in a row form the
myelin sheath
myelin sheath, gaps between myelin called nodes of
ranivier
Synapse/Synpatic Cleft neuro transmitter release from one axon terminals
where electrical turns to chemical
afferent information going into the brain
efferent information out of brain
