Whe examining hyaline cartilage under a microscope, one expects to find which of the following?

A. canaliculi
B. microscopic blood vessels
C. peptide fibers
D. Volkmann's canals


I thought the answer should have been C, but EK says it's B. I thought cartilage has no blood vessels. Is hyaline cartilage an exception?

I would go with elimination of wrong answers first. D and A are in bones, which leaves the choice between C and B. Peptide fibers are found in elastic cartilage, and according to my anatomy book, the fine collagen fibers cannot be seen in hyaline cartilage. That leaves choice B.

However, my anatomy book also states that cartilage does not contain nerves or blood vessels. The nerves and vessels are located in the perichondrium which surrounds the cartilage and the cells in the cartilage receive nutrients from diffusion... That eliminates the last choice. There is no RIGHT answer. Send the question to EK and tell them that you want your money back.

thought it would be C as well, how in the world does it have blood vessels when the reason cartilage can't repair itself is because it does NOT have blood vessels

key word is microscopic and peptide fibers would be muscle, as an example, which contains proteins.

dude collagen is basically a peptide fiber and collagen is abundant in cartilage, i think this question is crap lol

yea i was just trying to rationalize their answer, but i agree it is crap

Another person in agreement. Especially when this is one of those cut and dry things where the books specifically say "NO blood vessels," etc.
