synapse.
Thank you!!!
Complete each sentence to assess your knowledge of neurotransmitter storage and release at a typical neuronal synapse, SNARE As action potentials propagate along a myelinated fiber, they jump from one node of Ranvier to the next and for this reason such propagation is called reuptake presynaptic Eventually, the action potential reaches the terminal of the neuron postsynaptic Depolarization in the terminat...

If necessary, refer to Animation: Chemical Synapses. When an action potential reaches the axon terminal: sodium ions are released from the axon terminal, enter the cell body of the postsynaptic neuron through its sodium channels, and may initiate an action potential in that neuron. neurotransmitter molecules are released from the axon terminal and bind to receptors on the postsynaptic neuron, causing either an inhibitory hyperpolarization or an excitatory depolarization. neurotransmitter molecules are released from the axon terminal, bind to and...

Passage IV (Questions 114-117) Electrical impubses are transferred from one neuron to another via a synapse. Synapses can be electrical or chemical. In response to an electrical stimalus such as an action potential the presynaptic neuron in a chemical synapse releases a neuro- transmitner across a small space between the two neurons known as a symaptic cief. Neurotransmitiers may have excita- ory...

INFORMATION ABOUT IMAGE G FOR QUESTIONS 12-15:
GABAB receptors (GABABRs) are
G-protein-coupled receptors that can be found on both pre- and
postsynaptic neurons. When they are activated by GABA, they can
have a range of effects. For the synapse you are studying in the
following questions, the effects of GABABRs are
indicated in IMAGE G.
You are doing a series of experiments in which you are recording
from the pre- and postsynaptic cell at a synapse. The experiments
