Answer
No, invertebrate axons do not have nodes of
Ranvier.
- Nodes of Ranvier are the gaps formed by myelin sheath in
the myelinated neurons.
- The nerve impulse jumps from one node of Ranvier to other in
order to pass through the axon.
- Invertebrate axons do
not posses myelin sheath around the axon and hence it do not
have nodes in between.
- Invertebrate neurons will have continous condition which is
slower than the saltatory conduction present in myelinated
neurons.
- Due to lack of myelin sheath in invertebrates, it does not have
nodes of Ranvier.
