Nerve Cells

1. a type of neuron which has two processes a axon and a dendrite
3. these cells have a protective role transforming into a special macrophage which phagocytizes unwanted substances.
4. neuroglia cells which form a barrier between cerebrospinal fluid and tissue fluid bathing the cells of the CNS.
5. the conducting region of the neuron, generating impulses and transmits them.
7. one principle cell of nervous tissue which which support and wrap around the more delicate neurons
8. neuroglia cells which function like oligodendrocytes but exclusively in the PNS
10. the main receptive or input regions of a neuron
12. a type of neuron which has three or more processes, one axon the rest dendrites

2. neuroglia cells which produce an insulating covering around cells called a myelin sheath
5. neuroglia cells which support and brace the neurons while attaching them to a nutrient supply
6. is a part of a neuron, has a large nucleus and cytoplasm
8. neuroglia cells which function like astrocytes but exclusively in the PNS.
9. a type of neuron which has a small cell body and proximal and distal branches function as sensory neurons
11. one principle cell of nervous tissue which are excitable and transmit electrical signals
