Neural Signaling and Nervous Tissue Quiz

What is the function of oligodendrocytes in the central nervous system (CNS)?

• Provide an insulating material that surrounds axons

• Receive stimuli from visual receptors in the eye

• Transmit information to motor neurons

• Interpret and determine an appropriate response

Which cells provide an insulating material that surrounds axons in the peripheral nervous system (PNS)?

• Oligodendrocytes

• Schwann cells

• Neural receptors

• Motor neurons

What is the process of sensory neurons transmitting information to the central nervous system (CNS) called?

• Reception

• Transmission

• Integration

• Actual response

During neural signaling, what happens in the integration stage?

• Stimuli are received by visual receptors in the eye

• Sensory neurons transmit information to the CNS

• Information is interpreted and an appropriate response is determined

• The CNS transmits information to motor neurons

What is the final stage of neural signaling where muscle/glands receive information and instruction from motor neurons?

• Reception

• Transmission

• Integration

• Actual response

What is the function of myelin sheaths in neural tissue?

• To conduct action potentials slowly

• To conduct action potentials rapidly

• To provide insulation for unmyelinated axons

• To interpret and determine an appropriate response

Where are nodes of Ranvier located?

• In the myelin sheath

• In the synaptic cleft

• In the presynaptic terminal

• Gaps in the myelin sheath

What is the term for groups of neuron cell bodies and their dendrites with very little myelin?

• Gray Matter

• White Matter

• Nuclei

• Ganglion

Which term is used to describe bundles of parallel axons and myelin sheaths in the central nervous system (CNS)?

• Gray Matter

• White Matter

• Nuclei

• Ganglion

What type of channels are opened by neurotransmitters?

• Leak channels

• Gated channels

• Chemically gated channels

• Voltage gated channels
