Slide 2:  Overview

Slide 3:  The Action Potential causes ____________________channels to open in the synaptic terminal.

Slide 4: The neurotransmitter binds onto a _____________ on the postsynaptic membrane. The

receptor is part of a____________ channel. The result is that the postsynaptic membrane may ___________

or ____________________ .

Slide 5: There are two ways to remove a neurotransmitter from the

synapse: 1) _____________________and 2) ___________________________.

Acetylcholine is broken down by ___________________in the synaptic cleft. Dopamine is broken down by
_______________________(enzyme) in the axon terminal (Look up).

Slide7:  The receptor determines the action of a given neurotransmitter.

Slide 8: Cholinergic receptors are of two types by function: 1) _______________
and 2) ______________________.

They are of two types by their binding of 1) __________________
and 2) _________________________.

Slide 9: Norepinephrin and epinephrin receptors are called ________________-ergic.
They are classified as ________________
and  ___________________. They are found in the ____________________N. S.

Click on Synaptic Potentials

Slide 1: ____________________are incoming signals to the neurons.

Slide 2: Review

Slide 3: Action Potentials are _______________  ________________  events

Slide 4: What was the value (mv) of the EPSP?  ________________?

What is the threshold voltage (define)  __________________________________________

_______________________________________________________________________

Give its value (mv). ______________

The IPSP_____________________-polarizes the membrane.

Slide 5:  Potentiation or summation can occur if action potentials are entrained. If Ca ⁺⁺ ion entry

decreases in the axon terminal by a type synapse, the effect is called _________________________.

Because they vary in amplitude, synaptic potentials are called ________________________.

Slide 6: Unlike the action potential, synaptic potentials decay with increasing  ____________________.

Slide 7: Where one synapse fires repeatedly in a short period of time, a _______________________(type)

summation occurs.

Slide 8: IPSPs can summate with EPSPs. The closer the synapse is to the

of the target neuron, the greater the effect on the neurotransmission.
