Ch.2 Activation of receptors and postsynaptic potentials
Help!
|
|
||||
|---|---|---|---|---|---|
| postsynaptic receptors | show 🗑
|
||||
| neurotransmitter-dependent ion channels | show 🗑
|
||||
| show | a molecule of the appropriate neurotransmitter attaches to it, the ion channel opens
🗑
|
||||
| show | neurotransmitters bind with the receptor and activates a G protein which activates an enzyme that stimulates the production of a chemical called a second messenger which travels through the cytoplasm and attach themselves to nearby ion channel an open
🗑
|
||||
| show | activated by an enzyme to cause ion channels to open.
🗑
|
||||
| show | sodium, potassium, chloride, calcium
🗑
|
||||
| excitatory postsynaptic potential (EPSP) | show 🗑
|
||||
| inhibitory postsynaptic potential (IPSP) | show 🗑
|
||||
| show | the opening of these channels serves to neutralize EPSP's
🗑
|
||||
| show | depolarizes the membrane producing EPSP's, but calcium released into the terminal button and triggers the migration of the synaptic vesicles and the release of the neurotransmitter.
🗑
|
||||
| calcium in dendrites in the postsynaptic cell | show 🗑
|
||||
| show | the process is an extremely rapid removal of neurotransmitter from the synaptic cleft by the terminal button
🗑
|
||||
| enzymatic deactivation | show 🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
