Understanding Synapses

What is the primary focus of the lesson on synapses according to the exam guidelines?

• The formation of vesicles

• The structure of neurons

• The significance of synapses

• The chemical reactions in synapses

What is the space between the terminal branches of one neuron and the dendrites of another called?

• Dendrite

• Axon

• Vesicle

• Synapse

How do neurons communicate with each other across the synapse?

• Through neurotransmitters

• Through electrical impulses

• By magnetic fields

• By direct contact

What are neurotransmitters packaged in before they are released into the synapse?

• Axons

• Dendrites

• Vesicles

• Receptors

What happens when vesicles burst at the axon terminal?

• They create a new synapse

• They release neurotransmitters into the synapse

• They destroy the axon terminal

• They form new neurons

What is the role of receptor regions on the dendrite side of the synapse?

• To send messages to the axon

• To receive and convert chemical messages

• To create neurotransmitters

• To destroy neurotransmitters

Why is it important that the direction of flow in a synapse is only one way?

• To prevent messages from bouncing back

• To allow multiple messages at once

• To increase the speed of transmission

• To enhance the strength of the signal

What is the benefit of using multiple neurons at the same time in synaptic transmission?

• It increases the speed of transmission

• It allows a single message to reach multiple neurons

• It strengthens the signal

• It prevents signal loss

What does the concept of 'filtering out' in synapses refer to?

• Reducing signal strength

• Increasing signal speed

• Ignoring unnecessary impulses

• Enhancing important signals

Why might your body choose to ignore certain pain signals while sitting?

• Because the signals are too strong

• Because the signals are too weak

• Because you are not in danger

• Because the signals are too frequent
