Question

Generally, people of old age complain of stiff joints. What do think of a possible reason for such a type of situation?

Answer 1

Hint: The inclination, which involves joint movement, is restricted or troublesome, known as Joint stiffness. Due to the agony, the inclination is not brought about by shortcoming or hesitance to move the joint. However, some people who have firmness can be equipped to move the joint through its full scope of movement; thus, this movement can require power.

Complete answer:
A few joints like the shoulder joint, the knee joint should be held immovably in position to be lubricated. Such joints contain a greasing liquid called synovial liquid, which fills in as a pad between the bones and eliminates grating during developments. Synovial liquid greases up your joints for smooth development. With age, this liquid abates, causing stiffness in joints.
As we age, the joint movement becomes stiffer and less adaptable because the measure of greasing liquid inside the joint reduces, and the ligament gets slender. In general, ligaments will abbreviate and lose some adaptability, causing the joints to feel hardened.
Elderly individuals complain about stiff joints due to their less stamina, loss of CaPO4(calcium phosphate), making their bones powerless. Huge numbers of these age-related changes to joints are brought about by the absence of exercise or any physical activity. Movement of the joint, and the related 'stress' of movement, helps keep the liquid moving. Being dormant makes the ligament contract and solidify, diminishing joint versatility.

Note:
The abatement of synovial liquid, which is available in the middle of joints to grease up bones, causes elderly individuals or old people to complain about stiff joints or joint agonies. Stiff joints even outcomes with the loss of their strength and loss of calcium phosphate in bones, making their bones feeble. With age, the size of the hyaluronic corrosive particles in your joints diminishes, hindering its capacity to fill in as successfully in support cushioning and lubrication.
