Hi, everyone. Here is our next question. It says, identify which of the following is matched correctly. Choice. A bipolar neurons and brain B, multipolar neurons and ears. C bipolar neurons and eyes or D multipolar neurons and nose. So clearly, the important distinction here is what is the difference between a bipolar and multipolar neuron. And we can recall that a bipolar neuron is a neuron with only two processes. And that would be one dendrite n one axon and these type of neurons are mainly found in sensory organs. Then if a bipolar neuron is a neuron with only two processes, you can probably guess that a multipolar neuron can have more than two. So multiple processes again, usually consisting of one axon but multiple dendrites. So we have a big clue that the bipolar neurons are mainly found in sensory organs. So we look at our answer choices. Choice A has bipolar neurons in the brain. But that wouldn't correspond with the idea that bipolar neurons tend to be associated with sensory organs. So we eliminate choice. A choice B is multipolar neurons and the ears, but the ears are one of those specialized sensory organs. So we'll eliminate that. Joy C says bipolar neurons and eyes. Well, this is correct. The eyes are a sensory organ and tend to have these bipolar or organ bipolar neurons, excuse me. And finally choice D multipolar neurons and the nose. Well, the no nose is an example of a sensory organ that has bipolar neurons. So choice D is not correct. So again, we have the correct match in choice C bipolar neurons and eyes. See you in the next video.
