Neural Communication Quiz

What is transduction?

• Conversion of one form of energy to another

• Communication between neurons

• Generation of action potentials

• Release of neurotransmitters

Which sensory system converts light into neural activity?

• Visual system

• Olfactory system

• Gustatory system

What type of energy is involved in neural communication?

• Electrochemical energy

• Mechanical energy

• Thermal energy

• Nuclear energy

What determines the generation of an action potential?

• Neural integration

• Neurotransmitter release

• Axon hillock

• Presynaptic cell

What happens when the threshold of excitation is reached?

• An action potential is fired

• Resting potential is maintained

• Neurotransmitter release is inhibited

• Voltage-dependent potassium channels open

What is the function of the axon hillock?

• Integrate and generate action potentials

• Receive and process sensory information

• Release neurotransmitters

• Maintain the structural integrity of the neuron

Which sensory system is responsible for detecting smells?

• auditory system

• tactile system

• olfactory system

What is the role of voltage-dependent potassium channels in neural communication?

• Regulate depolarization phase of action potentials

• Regulate repolarization phase of action potentials

• Control synaptic transmission

• Initiate action potentials

What is the function of the dendrites?

• Receive signals from other neurons and transmit them to the cell body.

• Protect the neuron from damage

• Store and release neurotransmitters

• Generate electrical signals

What is the role of myelin sheath in neural communication?

• The myelin sheath inhibits neural communication.

• The myelin sheath has no role in neural communication.

• The myelin sheath slows down neural communication.

• The myelin sheath insulates and speeds up neural communication.
