Hey, everyone. Let's take a look at this question together which of the following statements about axons is true. Is it answer choice? A? They appear as short branches, answer choice B, they have a uniform width throughout the length. Answer choice C they are branched throughout or answer choice D they receive signals from the neurons upstream. Let's work this problem out together to try to figure out which of the following answer choices contains a statement about axons that is true. So in order to solve this question, we have to recall what we have learned about axons to determine which of the following statements contains a true statement about axons. And some information that we can recall about axons is that axons are long and slender projections of neurons, which axons also have a consistent and uniform diameter along the length. And unlike dead rights, which often exhibit branching and receive signals from other neurons. Axons are specialized for sending signals away from the cell body. So looking at our answer choices, which of the following answer choices contains a statement about axons that is true. And we can identify in answer choice B which says that axons have a uniform width throughout the length which we know is true. So they have that consistent and uniform diameter along the length of the axon. So answer choice B is the correct answer. And all other answer choices are incorrect since they do not contain a true statement about axons. Axons are not short branches, they are not branched throughout and they do not receive signals from the neurons upstream. So answer choice B is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
