Imagine you're a doctor, and a middle-aged patient comes to you with a medical condition that is causing their collagen fibers to become weak. What affect would this have on the sutures in their skull?
A
Sutures are made of short collagen fibers, so their sutures would loosen and become fragile.
B
There is never fibrous connective tissue in sutures so it wouldn't have an effect.
C
At this patient's age their sutures will have ossified; therefore, this condition won't affect their sutures.
Verified step by step guidance1
Understand the role of collagen fibers in the body: Collagen is a key structural protein found in various connective tissues, including skin, tendons, and bones. It provides strength and elasticity.
Identify the composition of sutures in the skull: Sutures are fibrous joints made primarily of short collagen fibers, which connect the bones of the skull.
Consider the patient's age: In middle-aged individuals, the sutures in the skull typically ossify, meaning they transform from fibrous tissue into bone over time.
Evaluate the impact of weak collagen fibers: Since the sutures have ossified in a middle-aged patient, the weakening of collagen fibers would not affect the sutures as they are no longer primarily composed of collagen.
Conclude the effect on the sutures: The condition causing weak collagen fibers would not impact the ossified sutures in a middle-aged patient, as the sutures have already transitioned to bone.
