A young woman sees her doctor with complaints that the bones in her left knee regularly dislocate, or move out of their usual pl
ace, painfully. Which of the following is the most likely conclusion to be drawn from this? Her knee joint's synovial fluid is not an effective lubricant between her bones.
Her bones have become perforated and brittle due to lack of calcium in her diet.
Her cartilage has deteriorated, providing less cushioning and causing her pain.
Her knee ligaments are weakened or injured so they can't stabilize the bones
Option D, Her knee ligaments are weakened or injured so they can't stabilize the bones
Explanation:
Ligaments act as a strong bands of body tissue whose main function is to provide connection between two bones or cartilages. It also supports bones and cartilages.
One of its major function is to provide strength and support to a joint so that it do not move too far from its line and get dislocated.
Here, the young woman has knee dislocation issue and since supporting a joint is the function of ligand , it is sure that some problems are there with the ligand
Her knee ligaments are weakened or injured so they can't stabilize the bones
Explanation:
Ligaments are dense connective tissues that serve to connect bones to each other. Ligaments are made by definite arrangement of collagen fibers in particular pattern. Weakening or injury to ligament makes the joints unstable. Since ligaments are not strong enough to hold the bones together, weakened or injured ligaments lead to bone dislocation. The woman with complaint of regular bone dislocation in her left knee must have weak or injured ligaments that can’t stabilize the bones.
Complex molecules are made up of other elements bonded with carbon. Carbon is able to bond with other molecules so easily because it has four valence electrons.
