Front

What is the primary function of oligodendroglia in the nervous system?

Back

To form the myelin sheath around CNS neurons.

Front

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

Front

Define interneurons and their function in the nervous system.

Back

Interneurons are nerve cells that connect sensory and motor pathways, facilitating communication between the CNS and PNS.

Front

What is the significance of dopamine in the nervous system?

Back

Dopamine is a neurotransmitter that plays a key role in movement and coordination; its deficiency is linked to Parkinson's disease.
