Neuron Structure and Function Quiz

During a biology class, Evelyn asked which part of the neuron is responsible for receiving signals from other neurons. What should the teacher answer?

• Axon

• Soma (cell body)

• Dendrites

• Terminal buttons

Arjun is learning about neurons in his biology class. What is the function of the myelin sheath in a neuron?

• To receive signals from other neurons

• To protect the soma

• To insulate the axon and speed up message transmission

• To connect neurons to muscles

In a classroom experiment, Benjamin is studying the structure of a neuron. Where are the terminal buttons located in a neuron?

• At the end of the dendrites

• At the end of the axon

• Surrounding the soma

• Inside the myelin sheath

During a biology class, Abigail asked, 'What is the main function of the soma (cell body) in a neuron?'

• To transmit electrical signals

• To receive signals from other neurons

• To house the nucleus and maintain cell function

• To insulate the axon

Charlotte and Kai are studying how neurons work in their biology class. What is the function of the myelin sheath in a neuron?

• To transmit electrical signals

During a science experiment, Priya observed a sudden change in the electrical activity of a neuron. What causes this action potential in a neuron?

• Changes in the flow of charged molecules (ions) across the neuron's cell membrane

• The release of neurotransmitters

• The formation of synapses

• The breakdown of myelin sheath
