| communicate information to the muscles and glands of the body. Simply blink your eyes activates thousands of motor neurons | show 🗑
|
||||
| communicate information between neurons. By far, most of interneurons connect other interneurons | show 🗑
|
||||
| short branching fibers extending from the cell body receive messages from other neurons or specialized cells many branches give it greater surface ares, which increases the amount of information the neuron can receive | show 🗑
|

| is a single, elongated tube that extends from the cell body in most, though not all , neurons (some neurons do not have axons) carry information form the neuron to other cells in the body, including other neurons, glands, and muscles vary by length | show 🗑

🗑
|
||||
| each neuron requires a minimum level of stimulation from other neurons or sensory receptors to activate it. This minimum level of stimulation is called the neurons...? | show 🗑
|
||||
| show | Resting Potential
🗑
|
||||
| there is no such thing as partial action potential, either it happens all the way to the end of the axon or it does not happen at all | show 🗑
|
||||
| following the action potential occurs during which the neuron is unable to fire lasts for about a thousandth of a second or less during this time the neuron depolarized and reestablished the negative inside, positive outside | 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.
