|---|---|---|---|---|---|
| Nervous System | refers to body's electrochemical communication system
🗑
|
||||
| Neuron/Nerve Cell | basic unit of nervous system
🗑
|
||||
| Neuroscience | mult-disciplinary study of the nervous system(biology and etc)
🗑
|
||||
| Nervous system characteristics; complexity | brain composed of billion of nerve cells
🗑
|
||||
| Integation | brain coordinates & integrates information from many sources
🗑
|
||||
| Adaptability | brain is capable of change
🗑
|
||||
| Electrochemical Transmission | brain uses electrical & chemical communication
🗑
|
||||
| Pathways in the Nervous System/ Afferent Nerves | recieve incomeing/senory information from the body(approach brain)(enter)
🗑
|
||||
| Efferent Nerves | send motor commands from brain to muscles and body(exit the brain)
🗑
|
||||
| Neural Networks | integrate sensory input & motor output
🗑
|
||||
| Central Nervous System | brain & spinal cord (central)
🗑
|
||||
| Peripheral Nervous System (side) | PNS carries messages to & from CNS & the organs, glands, & skeletal muscles
🗑
|
||||
| Somatic Nervous System | carries senory information to the CNS & motor information from the CNS to skeletal muscles
🗑
|
||||
| Autonomic Nervous System | carries info to & from CNS to body's organs & glands
🗑
|
||||
| Sympathetic | nervous system(arousing)(sensative)
🗑
|
||||
| Parasympathetic | calms the body
🗑
|
||||
| Neuron | basic unit to the nervous system that serves to process info
🗑
|
||||
| Glial Cells | provides support & nutritional benefit(feeds cells)
🗑
|
||||
| Parts of a basic cell;soma/cell body | contains nucleus
🗑
|
||||
| Dendrite | recieves info & channels it toward cell body
🗑
|
||||
| Axon | carries electrical info away from cell to other cells
🗑
|
||||
| Myelin Sheath | insulation that helps message travel faster; implicated in Multipe Sclerosis
🗑
|
||||
| Communitcation in the Cell; Resting Potential | is the difference in voltage between the inside & outside of axon membrane; NA+ions are in high concentration outside of cell wall, while K+ions are in high concentration inside the cell
🗑
|
||||
| Resting Potential part B | at rest, some K+ions can leave the cell causing the exterior of the nerve cell membrane to be slightly positive relative to the inside of the axon
🗑
|
||||
| Action Potiential | NA+gates at base of neuron open; NA+ rushes into neuron, temporarily altering charges present at membrane; the charge on K+ion cause next gate to open; gates open & close sequentially down the length of the axon
🗑
|
||||
| Action Potiential part B | when the gate closes, K+ions flow out of the neuron to re-establish resting potiential
🗑
|
||||
| All or None Principle | when electical impulse is released, it travels down the axon at the same speed(resulting in neurotransmisson)
🗑

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.
