Neuron’s Role in Communication Within the Brain by Camille McEvoy https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7 en-us 2023-03-10 20:14:39 UTC 2023-03-11 02:21:25 UTC hello@padlet.com Main Function of Neurons camillemcevoy2003 https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512309151 Neurons respond to stimuli and transmit signals (YouTube, 2015). They are protected by the glial cells (YouTube, 2015). They process all the input and output information in the Central Nervous System (Stufflebeam, 2006). There are estimated 200 billion neurons in the brain alone, not including the neurons flowing all through the rest of the body (Stufflebeam, 2006). ]]> 2023-03-10 20:24:51 UTC https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512309151 Main Function of Glial Cells camillemcevoy2003 https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512312414 Glial cells outnumber the number of neurons in the body. Their main function is to protect and surround the neurons (YouTube, 2015). Astrocytes, Microglial, Ependymal, Oligodendrocytes, Satellite, and Schwann are the types of glial cells (YouTube, 2015). ]]> 2023-03-10 20:28:54 UTC https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512312414 Parts of the Neuron camillemcevoy2003 https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512315484 There are four main parts of the neuron (Stufflebeam, 2006). The first is the cell body which is the control center (Stufflebeam, 2006). Second, the dendrites this is the ingoing signal and third, the axon is the outgoing signal (Stufflebeam, 2006). The neuron may have thousands of dendrites but will always have 1 axon (Stufflebeam, 2006). The fourth part is the axon terminal which is where the neurotransmitters lie (Stufflebeam, 2006). ]]> 2023-03-10 20:33:10 UTC https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512315484 Two Main Ions in Resting Potential camillemcevoy2003 https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512318857 Sodium and Potassium are the two main ions that remain in resting potential (Stufflebeam, 2006). ]]> 2023-03-10 20:38:18 UTC https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512318857 Repolarization camillemcevoy2003 https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512323848 When repolarization occurs, an outward movement occurs causing the channels to close and the membrane's potential to turn to normal (Stufflebeam, 2006). ]]> 2023-03-10 20:45:17 UTC https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512323848 Depolarization camillemcevoy2003 https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512452304 This is when sodium sodium channels open up and the sodium ions rush in (Stufflebeam, 2006). During this time the membrane will become more positive inside than on the outside (Stufflebeam, 2006). After this occurs the channels will then close (Stufflebeam, 2006). ]]> 2023-03-11 01:52:11 UTC https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512452304 Electric Signals camillemcevoy2003 https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512454387 Electric signals in neurons are similar to electrons that move across a wire to to electronic devices (Stufflebeam, 2006). For the neuron this occurs when ions move across the neuronal membrane (Stufflebeam, 2006). ]]> 2023-03-11 01:58:54 UTC https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512454387 Ions camillemcevoy2003 https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512454955 Ions function by moving across the membrane through channels that are opening and closing depending on the neurotransmitter(Stufflebeam, 2006). Ions are simply electrically charged particles (Stufflebeam, 2006). ]]> 2023-03-11 02:00:42 UTC https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512454955 Conclusion camillemcevoy2003 https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512457375 Stufflebeam's article allowed me to further understand how the central nervous system processes information. I was able to learn how neurons, ions, and glial function. I had no idea there was so many of all those in the brain. As well as furthering my understanding of depolarization and repolarization. ]]> 2023-03-11 02:08:50 UTC https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512457375 References camillemcevoy2003 https://padlet.com/camillemcevoy2003/yg8sgxw8bvhl3sd7/wish/2512461152 Neurons, synapses, action potentials, and neurotransmission.
