The Neuron’s Role in Communication Within the Brain by Mika Hall https://padlet.com/mistypaws14/9szsc64nbnhp0l7d By Mika Hall NorthWest University en-us 2021-03-11 23:06:16 UTC 2025-09-26 15:03:55 UTC hello@padlet.com What are the main functions? mistypaws14 https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300579198 There are four basic parts and these include the dendrites, cell body or soma, axons and the axon terminal  (Kolb, et al., 2019). 

Dendrites- Receives and processes electrical and or chemical signals from rootlike extensions  (Kolb, et al., 2019). 
Cell Body (soma)- Neuron's core which carries the genetic information, maintains the structure and provides energy to complete a given task.  (Kolb, et al., 2019) 
Axons-Transmits electrical or chemical signals to to other cells. Insulated by myelin which helps to conduct signals (Kolb, et al., 2019).
Axon Terminal- Where the message is carried out and connected to other neuron dendrites  (Kolb, et al., 2019). ]]> 2021-03-11 23:12:13 UTC https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300579198 What are neurons and glial cells? What one has the most abundant amount of cells? mistypaws14 https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300579798 Neurons are the conducting cells of the nervous system  (Kolb, et al., 2019). Glial cells or neuroglial are more numerous than neurons and do not conduct nerve impulses but rather they are a caretaker for neurons  (Kolb, et al., 2019). ]]> 2021-03-11 23:12:34 UTC https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300579798 What are the four parts of a neuron and what do they do? mistypaws14 https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300586534 2021-03-11 23:16:05 UTC https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300586534 How are action potentials different from other electrical signals? mistypaws14 https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300587423 Action potentials are electrical signals carried along neurons and allow neurons proper signaling to move the body or do any action much like electronic devices. 
When you point a tv remote and press the turn on/ off towards the tv, it causes an unseen action which promptly starts up the tv. In the same way, our neurons send billions of messages and continuously receives and relays those messages until that action is done  (Kolb, et al., 2019). ]]> 2021-03-11 23:16:33 UTC https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300587423 What are ions and how do they move in and out of a cell? mistypaws14 https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300588168 Ions are atoms or groups of atoms that gain an electrical charge by losing or acquiring electrons  (Kolb, et al., 2019).
To enter or exit the neuron, ions must pass through special proteins called ion channels which all have different configurations such as closed, inactive and open. These ion channels are sensitive to their environment allowing them to change their shape accordingly and respond to voltage changes. ]]> 2021-03-11 23:16:58 UTC https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300588168 What are the two main ions that contribute to the resting potential? mistypaws14 https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300589034 Resting potential is the result of different concentrations inside and outside the cells with Na+ and K+ ions inside and out of the cell  (Kolb, et al., 2019). ]]> 2021-03-11 23:17:26 UTC https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300589034 What happens during the depolarization or rising phase of the action potential? mistypaws14 https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300589461 When a nerve impulse stimulates ion channels to open, positive ions flow into the cell and cause depolarization which then leads to muscle cell contraction. ]]> 2021-03-11 23:17:40 UTC https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300589461 What happens during the repolarization or falling phase of the action potential? mistypaws14 https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300594400 During repolarization, the sodium gates close and potassium gates open allowing potassium to rush out of the axon  (Kolb, et al., 2019). This returns a negative charge to the inside of the axon reestablishing the negative potential. ]]> 2021-03-11 23:20:16 UTC https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1300594400 Conclusion mistypaws14 https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1307994317 The value of a neuron and their parts are that by understanding neurological structures and functions, neuropsychology can determine the correlation of brain related strengths and or weaknesses and evaluate how to help whether it is the cause of a neurological impairment or a cause of treatment. 
A neuron has four parts and all of them help to decode signals that are much like an electrical signal from a tv remote to a tv and all possible actions between the neurons and ions within it lead to actions called potentials which indicate what concentrations are held within the cells and the charges within them. ]]> 2021-03-14 20:00:07 UTC https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1307994317 References mistypaws14 https://padlet.com/mistypaws14/9szsc64nbnhp0l7d/wish/1308046866  ● Kolb, B., Whishaw, I., & Teskey, G.
