Neuroanatomy Basics Quiz

What is the primary function of the Nodes of Ranvier in a neuron?

• To store neurotransmitters

• To allow ions to flow in and out, speeding up nerve signal transmission

• To produce myelin

• To connect neurons to blood vessels

Where is the action potential initiated in a neuron?

• Dendrite

• Axon Hillock

• Synapse

• Myelin Sheath

Which type of glial cell is responsible for myelinating neurons in the central nervous system (CNS)?

• Schwann Cells

• Microglia

• Oligodendrocytes

• Astrocytes

What is the role of Schwann cells in the nervous system?

• To myelinate neurons in the peripheral nervous system (PNS)

• To act as immune cells in the CNS

• To transmit electrical signals

• To produce neurotransmitters

Which type of synaptic connection involves the axon of one neuron connecting to the dendrite of another?

• Axosomatic

• Axodendritic

• Axoaxonic

• Dendrodendritic

What is the primary function of microglia in the central nervous system?

• To transmit electrical signals

• To clean up debris and fight infection

• To produce myelin

• To store nutrients

What is myelination?

• The process of removing waste from neurons

• The process of covering axons with myelin to speed up electrical signal transmission

• The process of producing neurotransmitters

• The process of forming synaptic connections

Which type of synaptic connection involves the axon of one neuron connecting to the cell body of another?
