Question

Sprain of body is due to pulling of
A)Muscles
B)Ligament
C)Tendons
D)Nerves

Answer 1

Sprain is referred to the wear and tear of the elastic tissue around the joints. It is due to some kind of sudden movement. It causes damage to soft tissues of the body It can last for about two weeks.

Complete answer:
The excess pulling of the ligaments causes sprain. Ligaments connect bone to bone and provide support to the joints limiting their movement. The stretching and tearing make joints unstable. The ligaments are found in ankles, shoulders, elbows etc. Ligaments are composed of fibrous collagen tissue. The main function of the ligament is to provide support to the bones and prevent the breakage of bones from each other. Our body contains around 900 joints.

Muscles- The muscle is a soft tissue which is found in all animals. The muscle cells are made up of actin and myosin filaments which slides over one another causing contraction and facilitating movement. The function of muscles is to generate force and cause motion.

Tendons- It is a tough band of connective tissue which connects muscles to bones. It is capable of holding tension. It is made up of collagen protein.

Nerves- It is involved in control and coordination of the body parts. Nerves are the part of the nervous system. The nerves help in transmitting the impulses from parts of the body to the brain through chemical signals.

Hence, the correct answer is option (B)

Note: The tendons and ligament both are made up of collagen proteins. Tendons join muscle to bones whereas ligament join bone to bone. The tendons are inelastic whereas ligaments are elastic. Excess pressure on tendons causes tendonitis.
