Structure of Neuron- Neuron consists of a star shaped cell. Which is called Cyton.
The longest of the many thin filaments of a cyton is called an axon or axon.
Its other branched and small amplifications are called dendrites.
The axons themselves branch at their ends that end in a microscopic knot-like formation called synapse knots or synaptic knobs.
Axons are surrounded by a covering of fatty substances called medullary or myelin sheaths.
Where there is no medullary or myelin sheath, they are called nodes of Ranvier.
The part between two nodes is called internode.
Above the myelin sheath is a thin membrane called neurilemma.
It is made up of flat and vertical cells called Schwann cells.
When the axon is too long, it is called a nerve fibre.
