What is the relationship between the muscles crossing a joint and that joint\'s

Question

What is the relationship between the muscles crossing a joint and that joint's properties (ie: joint stability, mobility or range and type of motion)? When answering this question, assume muscles are balanced on all sides of the joint. The stronger the muscles crossing a joint, the more stable the joint The weaker the muscles crossing a joint, the less range of motion that joint has O The fewer muscles crossing a joint, the more types of motions a joint can create The stronger the muscles crossing a joint, the more likely that joint is to dislocate

Explanation / Answer

Answer:- Option A - The stronger the muscles crossing a joint, the more stable the joint.

Explanation:- Weak muscles in the joint region or crossing the joint cannot carry out the joint movement to the full capacity and strength. Thus weak muscles result in weakening of the joint with respect to stability, mobility and type of motion). Range of motion of the joint may not be affected, but the strength and stability in the joint and its motion is affected.Thus option B is not correct answer.

Fewer muscles may lead to imbalance of the joint. The balanced strong muscles are necessary for the proper stability. The stronger muscles on one side of a joint and weaker muscles on the other side of the joint may lead to dislocation. Thus option 3 and 4 are not correct answers.

The stronger muscles that are balanced on all sides of the joint ofter more stability to the joint.
