Quiz Synapse

Neurotransmitters are released from the

• Dendrites

• Post-synaptic neurone

• Presynaptic neurone

• Schwann Cells

W is

• Synaptic Terminal

• Neurotransmitters

• Dendrite

• Synaptic cleft

What is the chemical released by synaptic vesicles diffusing across a synapse to another nerve cell?

• Neurotransmitters

• Synaptic cleft

• Mitochondria

• Receptor

What generates a nerve impulse on the post-synaptic membrane? 

• Calcium binding with a receptor site
• Potassium leaking into the post-synaptic membrane 
• Neurotransmitter binding with receptor sites
• Neurotransmitter being removed from the synapse

How does neurotransmitter cross the synaptic cleft?

• Facilitated diffusion

• simple diffusion

• carrier mediated transport

• osmosis

Synapse can be found between:

• Synaptic terminal and dendrite

• Dendron and cell body

• Receptor and dendrite

• Synaptic terminal and effector

Which of the following are examples of neurotransmitter?

• Acetylcholine

• Noradrenaline

• Cerebrospinal fluid

• Dopamine

The conversion of signal at presynaptic membrane is

• Electrical signal to chemical signal

• Chemical signal to electrical signal

• Potential signal to electrical signal

• Potential signal to chemical signal

The conversion of signal at postsynaptic membrane is

• Electrical signal to chemical signal

• Chemical signal to electrical signal

• Potential signal to electrical signal

• Potential signal to chemical signal

There are large number of mitochondria at synaptic terminal / knob is to:

• Supply large amount of energy for transmission of impulse across synapse

• Supply nutrients to synapse

• Supply protein to receptor at postsynaptic membrane
