MUSCLE PHYSIOLOGY

Detailed explanation-1: -Sometimes called pulled muscles, strains commonly occur in the lower back and in the muscles at the back of the thigh (hamstrings).

Detailed explanation-2: -A muscle strain is an injury to a muscle or tendon (the tissue that connects a muscle to a bone) and can range from a minor stretch injury to a partial or complete tear of the muscle fibers or tendon. The injury often happens at the junction where the muscle and tendon meet (musculotendinous junction).

Detailed explanation-3: -In sports, it’s possible to pull almost any muscle. The most common sports strains affect the leg or groin muscles, such as the: Quadriceps-the muscle in the front of your thigh. Hamstring-the muscle in the back of your thigh.

Detailed explanation-4: -Muscles that cross two joints, such as the hamstrings (the hip and knee joints), the calf (the knee and ankle joints), and the quadriceps (the hip and knee joints) are the most susceptible to injury.
