Which of these is not a part of a neuron?
Meninges
Neurons are the basic units of the nervous system and its most important part is the brain. Every neuron is made up of a cell body, also called a soma, dendrites and an axon. Axons may sometimes be covered by a fatty insulating layer called the myelin sheath.
The three membranes - the dura mater, arachnoid, and pia mater, that line the skull and vertebral canal and enclose the brain and spinal cord is called meninges. The meninges do not form a part of the neuron.
