|---|---|---|---|---|---|
| show | an intricate network of cells that plays a vital role in processing information received through nerve pathways from the body and ind directing actions within the body.
🗑
|
||||
| show | a long, thin bundle of nerve tissue that extends from the base of the brain to the lower back
🗑
|
||||
| show | a sub-division of the PNS that carries sensory and motor information to-and-from the CNS
🗑
|
||||
| Sensory Afferent Nerves (PNS) | show 🗑
|
||||
| Motor Efferent Nerves (PNS) | show 🗑
|
||||
| show | a self-regulating sub-division of the PNS that connects the CNS to the body's internal organs and glands, providing feedback to the brain about their activities
🗑
|
||||
| show | a sub-division of the autonomic nervous system that helps to maintain the internal body environment in a steady, balanced state of normal functioning
🗑
|
||||
| Sympathetic Nervous System (PNS) | show 🗑
|
||||
| Axon (neuron) | show 🗑
|
||||
| show | structure at the end of an axon collateral
🗑
|
||||
| show | thin extension of a neuron that receives information from neighbouring neurons and transmits it to the soma
🗑
|
||||
| Interneuron (neuron) | show 🗑
|
||||
| Motor Neuron (neuron) | show 🗑
|
||||
| Myelin (neuron) | show 🗑
|
||||
| show | receives sensory information from both the external and internal environments and carries it to the CNS
🗑
|
||||
| Soma (neurons) | show 🗑
|
||||
| Astrocyte (glial cell) | show 🗑
|
||||
| show | Microglia are the brain’s immune cells, serving to protect it against injury or disease. The identify when something goes wrong in the body and removes the toxic agent. They also play a role in developing the brain.
🗑
|
||||
| Oligodendroglia (glial cell) | show 🗑
|
||||
| show | Located in the peripheral nervous system, Schwann cells myelinate neurons. They have similar functions as the oligodendrocytes in the CNS. They form the myelin sheath around the axons.

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.
