Neuron Structure and Function Quiz

What are the three main components of a neuron?

• Axon, dendrites, and synapse

• Cell body, axon, and dendrites

• Cell body, axon, and synapse

• Cell body, synapse, and nucleus

Which property allows neurons to respond to environmental changes?

• Durability

• Conductivity

• Excitability

• Flexibility

What unique structure is found in the neuron's cell body?

• Lysosomes

• Golgi apparatus

• Mitochondria

• Nissl bodies

What is the primary function of dendrites?

• Produce energy for the neuron

• Store genetic information

• Receive signals from other neurons

• Transmit signals over long distances

How are dendrites metaphorically described in the video?

• As a spider's web

• As a tree with branches

• As a river with tributaries

• As Don King's haircut

What is the role of the axon in a neuron?

• To transmit signals

• To store nutrients

• To protect the neuron

• To receive signals

What is the difference between fast and slow axonal transport?

• Fast transport moves substances quickly, slow transport moves them slowly

• Fast transport is only retrograde, slow transport is only anterograde

• Fast transport moves only towards the cell body, slow transport moves away

• Fast transport is used for repair, slow transport is not

Which diseases exploit fast axonal transport?

• Rabies and tetanus

• Influenza and measles

• Chickenpox and mumps

• Malaria and dengue

What is the primary function of slow axonal transport?

• To transmit signals quickly

• To repair axonal damage

• To store neurotransmitters

• To produce energy

What analogy is used to describe slow axonal transport?

• A car driving on a highway

• A train stopping at stations

• A plane flying non-stop

• A river flowing downstream
