Everyone. Let's take a look at this question together which of the following distinguishing features between tendons and apo neurosis is true. Is it answer choice. A tendons are flat and ribbon like while apo neurosis are cord like in shape. Answer choice B tendons are composed of collagen fibers arranged in a grid like pattern. While apo neurosis have parallel bundles of collagen fibers. Answer choice C tendons attach muscles to bones. While apo neurosis attach muscles to other muscles or answer choice D both answer choices B and C. Let's work this problem out together to try to figure out which of the following distinguishing features between tendons and apo neurosis is true. So in order to determine which of the following distinguishing features between both tendons and apo neurosis are true. Let's recall what we've learned about them individually so that we can determine which of the following distinguishing features between them is true. So starting off with tendons, we know that tendons attach the muscles to the bones, they have a cord like shape and they are also composed of collagen fibers that are in parallel bundles. And compared to tendons, we note that apo neurosis attach muscles to other muscles or bones and they also have collagen fibers that are arranged in a grid like pattern. So now that we know the differences between both tendons and apo neurosis, let's try to determine which of the following answer choices is correct. So answer choice A says that tendons are flat and ribbon like while apo neurosis are chord like in shape. Well, we know that the tendons are chord like in shape. So answer choice A is incorrect answer. Choice B says that tendons are composed of collagen fibers arranged in a grid like pattern. While apo neurosis have parallel bundles of collagen fibers, which we note that the tendons are composed of the collagen fibers in the parallel bundles and not the grid like pattern. So answer choice B is also incorrect, which means that answer choice D is also incorrect since it cannot be answer choice B which leaves us with the correct answer, which is answer choice C tendons attach muscles to bones. While Apo neurosis attach muscles to other muscles, which we know is a true statement. Since those tendons do attach the muscles to the bones and the apple neurosis, attach muscles to other muscles or to bones. So answer choice C is the only true statement and the correct answer.
