Multiple Choice

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?

Sutures are made of short collagen fibers, so their sutures would loosen and become fragile.

There is never fibrous connective tissue in sutures so it wouldn't have an effect.

At this patient's age their sutures will have ossified; therefore, this condition won't affect their sutures.

Verified step by step guidance

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.
