Neurotransmitter Functions and Processes

The video explores neural firing in AP Psychology, covering neuron types, action potentials, synapses, and neurotransmitters. It explains how neurons communicate through electrical impulses and chemical signals, detailing the roles of various neurotransmitters like acetylcholine, dopamine, and serotonin. The video also discusses the effects of excitatory and inhibitory neurotransmitters on neuron activity and provides resources for further study.

What type of neurons send information from sensory receptors to the brain and spinal cord?

• Motor neurons

• Mirror neurons

• Afferent neurons

• Interneurons

Which process must occur for a neuron to send a signal?

• Repolarization

• Depolarization

• Hyperpolarization

• Permeability

What is the space between two neurons called where neurotransmitters are released?

• Axon terminal

• Synaptic cleft

• Dendritic gap

• Neuronal junction

Which neurotransmitter is associated with muscle action, learning, and memory?

• Acetylcholine

• Dopamine

• GABA

• Serotonin

What is the role of dopamine in the body?

• Increases heart rate and alertness

• Affects movement, learning, and emotion

• Controls pain and pleasure

• Regulates sleep and movement

Which neurotransmitter is known as the 'feel good' chemical?

• Dopamine

• Endorphins

• Serotonin

• Glutamate

What happens during the process of reuptake?

• Neurotransmitters are reabsorbed

• Neurotransmitters are inhibited

• Neurotransmitters are destroyed

• Neurotransmitters are released

Which neurotransmitter is involved in excitatory messages and long-term memory?

• GABA

• Glutamate

• Serotonin

• Acetylcholine

What effect do inhibitory neurotransmitters have on a neuron?

• Cause immediate firing

• Increase the likelihood of firing

• Decrease the likelihood of firing

• Have no effect

Which neurotransmitter helps with sleep and movement by slowing down the nervous system?

• Dopamine

• GABA

• Serotonin

• Glutamate
