What is the main effect of myelin around an axon?
- A. It insulates the axon and increases conduction speed
- B. It produces every neurotransmitter
- C. It acts as the neuron's nucleus
- D. It prevents all ion movement at nodes
What are nodes of Ranvier?
- A. Gaps between two neurons
- B. Gaps between adjacent myelin segments
- C. Branches of dendrites
- D. Vesicles in an axon terminal
Dendrites of a typical neuron mainly
- A. receive signals and conduct them toward the cell body
- B. carry impulses only away from the cell body
- C. produce myelin in every neuron
- D. form blood vessels
A long neuronal process carries impulses away from the cell body toward distant targets. What is it?
- A. Nissl body
- B. Dendrite
- C. Axon
- D. Cell body
An axon loses its myelin sheath but remains structurally intact. Which change is most likely?
- A. The synaptic cleft closes
- B. Conduction becomes faster
- C. The nucleus disappears
- D. Impulse conduction becomes slower
The specific receptors for neurotransmitters in a synapse are present on .
- A. Schwann cell
- B. Pre-synaptic membrane
- C. Myelin sheath
- D. Post-synaptic membrane
Common mistakes in Neuron structure and nerve fibre types
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Imagining that the myelin sheath itself conducts the action potential.
- Treating dendritic branching and myelination as unrelated to neuronal function.
- Assumes myelin speeds conduction by increasing ion leakage everywhere.
- Assumes loss of insulation makes conduction faster.
