Front

What do axons running through the central nervous system form?

Back

Tracts.

Front

What is referred to as 'A' in a neuron diagram?

Back

Front

How are neurons classified according to structure?

Back

Neurons can be classified as unipolar, bipolar, or multipolar.

Front

What type of neurons have many processes that issue from the cell body?

Back

Multipolar neurons.

Front

What are the neuroglia of the peripheral nervous system?

Back

Satellite cells and Schwann cells.

Front

What is the primary function of the endoneurium?

Back

To protect and insulate individual axons.

Front

What is the difference between white matter and gray matter in the central nervous system?

Back

White matter consists of myelinated axons, while gray matter contains neuronal cell bodies and unmyelinated axons.

Front

What role do Schwann cells play in the peripheral nervous system?

Back

They form the myelin sheath around peripheral axons.

Front

What is the function of satellite cells in the peripheral nervous system?

Back

They support and protect neuronal cell bodies in ganglia.
