Which one of the following statements about ligaments is correct?

Question

BlackTom AI · Accepted Answer

When evaluating statements about ligaments, it's helpful to recall what ligaments do and their tissue characteristics.
Option 1 says a complete rupture interrupts the connection between bone and muscle. That describes tendons, not ligaments, since tendons connect muscle to bone. Ligaments connect bone to bone, so this statement misattributes the basic anatomy of ligaments.
Option 2 states that if torn they lead to joint instability. This aligns with the primary role of ligaments in stabilizing joints; damage or tearing reduces passive joint stability and can result in increased laxity and an unstable joint, which makes this option plausible and correct.
Option 3 claims ligaments contain a large proportion of elastic tissue. While ligaments do have some elastic components, their core structure is predominantly dense collagen, with relatively less elastic tissue compared to ligaments' counterpart tendons. The description of a large elastic content is not accurate for ligaments in general.
Option 4 asserts ligaments possess a rich blood supply and heal rapidly when injured. In reality, ligaments have a relatively poor blood supply compared with other tissues, which contributes to slower healing after injury. Therefore, this statement is incorrect.
Overall, the most accurate statement is that torn ligaments lead to joint instability, while the other options mischaracterize the anatomy, composition, or healing properties of ligaments.
