nodes of Ranvier(ran-veer)
The small gaps in the
myelin sheath between successive
glial cells along the
axon of a
neuron; also, the
site of high concentration of voltage-gated
ion channels.

microscope in the 18th century, it was discovered that the '
cancer poison' spread from the primary
tumor through the
lymph nodes to other sites ("metastasis").

meiosis.
