A person works an office job that requires them to be in a sitting position for 10 hours a day. They go home and sit until they go to bed. This person never exercises and rarely gets up to move around after being seated. Their joints begin to constantly feel stiff and painful. On a physiological level, what has happened to cause these symptoms?Multiple ChoiceBeing stuck in the same position for long periods of time causes the ligaments to physically decay, stiffening the joints.Lack of movement results in reduced blood flow in the vessels of the synovial membrane, reducing nutrient supply to ligaments which lose elasticity.Lack of movement causes the synovial membranes to stop producing synovial fluid, which then increases friction upon movement of the joints.Disuse of the joint causes ossification of the fibrocartilage, creating arthritic joints.
Question
A person works an office job that requires them to be in a sitting position for 10 hours a day. They go home and sit until they go to bed. This person never exercises and rarely gets up to move around after being seated. Their joints begin to constantly feel stiff and painful. On a physiological level, what has happened to cause these symptoms?Multiple ChoiceBeing stuck in the same position for long periods of time causes the ligaments to physically decay, stiffening the joints.Lack of movement results in reduced blood flow in the vessels of the synovial membrane, reducing nutrient supply to ligaments which lose elasticity.Lack of movement causes the synovial membranes to stop producing synovial fluid, which then increases friction upon movement of the joints.Disuse of the joint causes ossification of the fibrocartilage, creating arthritic joints.
Solution
The most accurate answer would be: Lack of movement results in reduced blood flow in the vessels of the synovial membrane, reducing nutrient supply to ligaments which lose elasticity.
When a person remains in a sedentary position for extended periods of time, it can lead to reduced blood flow, particularly in the synovial membrane which is responsible for producing synovial fluid that lubricates the joints. This reduced blood flow can lead to a decrease in the supply of nutrients to the ligaments, causing them to lose their elasticity and leading to stiffness and pain in the joints.
