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) _________________________.

(neurotransmitter) onto adrenergic receptors on cardiac and smooth muscle cells.

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.
