Synaptic Transmission

IPSP neurotransmitter causes __________ of the postsynapse.

• Depolarization

• Hyperpolarization

EPSP neurotransmitter causes __________ of the postsynapse.

• Depolarization

• Hyperpolarization

The following is an example of the excitatory postsynaptic potential (EPSP) neurotransmitter except for

• Acetylcholine

• Glutamate

• GABA

• aspartic acids.

The binding of the IPSP neurotransmitter to its receptor causes the opening of

• ligand-gated potassium channel

• ligand-gated sodium channel

An electrical synapse is a connection between two synapses via:

• Gap Junction

• Neurotransmitter

The following is an example of the graded potential, except for:

• Postsynaptic potential

• Presynaptic potential

• Generator potential

• Pacemaker potential

The name of the specialised gap between 2 neurons

• Dendrites

• Terminal buttons

• Synaptic Vesicles

• Synapse

When an action potential reaches the terminal button it causes...

• vesicles to migrate towards and fuse with the cell membrane

• neurotransmitter molecules to bind to the receptor sites on the postsynaptic cell

• enzymes to breakdown leftover molecules of neurotransmitter in the synaptic cleft

• chloride ions to flood into the postsynaptic cell

Neurotransmitter molecules diffuse across the synapse before binding to ...... on the post synaptic cell

• receptors

• schwann cells

• the nodes of Ranvier

• the axon hillock

Neurotransmitters are released from the....

• Dendrites

• Post-synaptic neuron

• Presynaptic neuron

• Axon
