WorksheetsTRANSMISSION OF IMPULSE
Total questions: 10
Worksheet time: 8mins
The transmission of information across the synaptic cleft involves conversion of the electrical impulse to a chemical impulse and is in (a) direction only.
What is the role of calcium ions during a synaptic transmission?
Generate action potential
Speed up the impulse transmission
Depolarisation of the synaptic knob
trigger the vesicles to move and fuse with the presynaptic membrane
Neurotransmitters are released from the
Dendrites
Post-synaptic neuron
Presynaptic neuron
Schwann Cells
What chemical is activated by the action potential in the presynaptic neuron that causes the vesicles containing neurotranmitters to move toward the synaptic cleft?
calcium
potassium
sodium
phosphorus
Neurotransmitters are released from presynaptic membrane to synaptic cleft by process of
Osmosis
Diffusion
Active transport
Exocytosis

voltage-gated channel
mechano-gated channel
ligand-gated channel
