The anatomical region of a multipolar neuron where the AP is initiated is the a. soma, b. dendrites, c. axon's initial segment, d. axon terminals.

Hey, everyone. Let's take a look at this question together which of the following neurons have a short process which divides into proximal and distal branches. Is it answer choice? A bipolar neurons, answer choice B unipolar neurons, answer choice C multipolar neurons or answer choice D pseudo unipolar neurons. Let's work this problem out together to try to figure out which of the following neurons is the correct answer. So we are looking for a neuron that has a single short process. And since we are looking for a single short process, we can eliminate answer choice A and answer choice. C since answer choice, a bipolar neuron has two processes and answer choice C multipolar neuron has multiple processes. So now we have to decide, are we looking for the unipolar neurons or the pseudo unipolar neurons? Well, we are looking for that neuron with this single short process that divides into both the proximal and distal branches. And we note that while the unipolar neuron has a single short process, the unipolar neurons lack the proximal branch. So that means that answer choice B is incorrect and answer choice D pseudo unipolar neurons is the correct answer since those are the neurons that have both a single short process and they divide into both the proximal and the distal branches. I hope you found this video to be helpful. Thank you and goodbye.
