What is the primary function of neuroglial cells in the nervous system?

  1. Conduction of electrochemical impulses along axonal fibers
  2. Secretion of neurotransmitters into the synaptic cleft
  3. Support, nutrition, and myelin-based insulation of neurons
  4. Storage and replication of genetic information in the brain
Show answer and explanation

Correct answer: Support, nutrition, and myelin-based insulation of neurons

While neurons transmit signals, neuroglia (such as astrocytes and oligodendrocytes) provide the essential microenvironment for neurons. They assist in nutrient transfer, debris removal, and the formation of myelin sheaths.
