4 Neurotransmission Quiz

What is the main role of the nervous system?

• To produce neurotransmitters

• To regulate body temperature

• To communicate information

• To control muscle movement

What allows neurons to send electrical signals called action potentials?

• Difference in electrical charge

• Difference in temperature

• Difference in blood flow

• Difference in hormone levels

What is the role of ions in creating an action potential?

• To generate heat

• To maintain cell structure

• To create electrical charge

• To produce neurotransmitters

How do ions move into or out of the cell?

• Through specialized channels

• Through the cell membrane

• Through the bloodstream

• Through the digestive system

What is the purpose of neurotransmitter chemicals?

• To regulate body temperature

• To maintain cell structure

• To create electrical charge

• To send signals between neurons

Which type of synapse allows for extremely quick synaptic transmission?

• Chemical synapse

• Electrical synapse

• Mitochondrial synapse

• Gap junction synapse

What is the role of voltage-gated calcium channels in neurotransmission?

• To generate heat

• To maintain cell structure

• To initiate release of neurotransmitters

• To produce action potentials

What is the process called when neurotransmitters are released from the presynaptic cell?

• Endocytosis

• Exocytosis

• Phagocytosis

• Pinocytosis

What is the main role of ionotropic receptors?

• To regulate body temperature

• To maintain cell structure

• To open ion channels

• To produce neurotransmitters

How do metabotropic receptors differ from ionotropic receptors?

• They work more quickly

• They have a more complex function

• They are found only in the brain

• They are not involved in neurotransmission
