Brain Structure and Functions

What is the order of the last 4 steps of neurotransmission?

• Recycle, New message, Synapse, Receptors

• Receptors, Recycle, Synapse, New message

• Synapse, Receptors, New Message, Recycle

• New message, Receptors, Synapse, Recycle

The message is received in the ______________.

• Synapse

• Dendrites

• Soma

• Axon

The combined messages generate an electrical impulse (Neuron fires) right after...

• The message travels through the axon

• The message is received

• The neurotransmitters attach to special receptors

• Neurotransmitters move across the gap (synaptic cleft) between neurons

In the step called (a)   , the neurotransmitters move across the gap between neurons.

What is the order of the first 4 steps of neurotransmission?

• Message Received, Neuron Fires, Axon, Neurotransmitters

• Axon, Neurotransmitters, Message Received, Neuron Fires

• Message Received, Neuron Fires, Neurotransmission, Axon

• Neuron Fires, Neurotransmission, Axon, Message Received

After neuron fires, the next place it travels is down the ________.

• Axon

• Dendrites

• axon terminals

• Soma

The order in which the signal travels in the neuron is________, _____________, ____________.

• Axon Terminals, Axon, Dendrites

• Dendrites, Axon, Axon Terminals

• Axon, Dendrites, Axon Terminals

• Dendrites, Axon Terminals, Axon

When the combined messages generate an electrical impulse, this is called...

• Axon

• Message Received

• Neuron Fires

• Neurotransmitters

In the last step of neurotransmission, the leftover neurotransmitters are __________________.

• destroyed

• absorbed

• recycled

• lost

What happens right after the neurotransmitters are released into the synapse?

• The message is received

• The impulse travels to the end of the axon

• The neurotransmitters are recycled (cleared from the synapse)

• The neurotransmitters cross the synaptic gap
