Neuron Structure and Function Quiz

Which part of the neuron receives incoming signals from other neurons?

• Axon

• Dendrites

• Myelin sheath

• Axon terminal

What is the main function of the axon?

• Store nutrients

• Receive electrical impulses

• Transmit impulses away from the cell body

• Protect the nucleus

The gap between two neurons where neurotransmitters are released is called the:

• Cell body

• Synapse

• Myelin sheath

• Axon hillock

What is the purpose of the myelin sheath?

• Slow down nerve impulses

• Store neurotransmitters

• Speed up the transmission of impulses

• Produce hormones

Which part of the neuron contains the nucleus?

• Axon terminal

• Synaptic cleft

• Cell body

• Myelin sheath

Neurons transmit information through which type of signal?

• Electrical only

• Chemical only

• Both electrical and chemical

• Magnetic

What do we call the branching structures at the end of the axon?

• Dendrites

• Axon terminals

• Synapses

• Nodes of Ranvier

Which of the following best describes a sensory neuron?

• Sends impulses from the brain to muscles

• Connects neurons within the brain and spinal cord

• Sends impulses from sense receptors to the brain/spinal cord

• Sends impulses from muscles to the brain

Motor neurons carry messages:

• From senses to the brain

• From the brain/spinal cord to muscles

• Between neurons in the brain

• Only within the spinal cord

What is the main part of the neuron that contains the nucleus?

• Axon

• Synapse

• Cell body (soma)

• Dendrites
