Voltage Changes During Neuron Impulse: 3rd Neuro Drawing

January 26, 2012 at 4:12 pm | Posted in action potential, Art, drawings, Kristin Bell, Mental Health, Mental Illness, neuron, neuron impulse, neuroscience, resting potential, voltage changes | Leave a comment

This is my third drawing for neuroscience class and it is showing the voltage changes and what is going on during the time when a neuron fires. The resting potential is about -70 millivolts, it shoots up to about +30 millivolts and then comes back down below the resting potential before it returns to the resting potential of -70 mV. This all happens in about 1-5 milliseconds depending on the particular neuron. FAST! :) Oh, also keep in mind that we have about 100-500 BILLION neurons in our heads too and nine times as many glial cells!!!

The Synapses: 2nd Drawing for Neuro Class

Here is my second drawing for neuroscience class. It is a picture of the synaptic gap basically and shows ionotropic and metabotropic receptors and other brain stuff. lol. :)

My Drawing of the Neuron

I had to draw the neuron and its parts for my neuroscience class. Here is what I made! Click the pic for a larger view. :) NOTE: I had to change my picture a bit, because I didn’t have the astrocytes connecting to the synapses. I also added a few other things. It is a little more crowded now, but I guess more correct. Another NOTE: I deleted the first two pics because they had mistakes. Here is the final version which may also have mistakes, but I think it is the most correct version. :)
