| What is responsible for spontaneous generation of impulses in the SA and AV node? | show 🗑
|
||||
| show | Occur in myocardial tissue (muscle) and the ventricular conduction (electrical)system.
🗑
|
||||
| show | Rapid depolarization due to rapid sodium channels opening (Na+ Influx), inside of cell becomes more positive.
🗑

||||
| What is Phase 1 in Fast Potentials? | show 🗑
|
||||
| What is Phase 2 in Fast Potentials? | show 🗑
|
||||
| show | Calcium ions (Ca++) stops influx and Potassium (K+) rapidly exits the cell. This returns the cell membrane to its normal electrical charge.
🗑

|
||||
| show | Relative Refractory Period
🗑
|

| show | Sinoatrial (SA)node
🗑
|
||||
| show | All mycocardial tissue both contractile and conductive.
🗑

| show | K+ Potassium
🗑

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.
