Final answer:
A strain is the tearing of muscle or tendon fibers, while a sprain is the tearing of ligaments, both occurring as a primary pathogenesis. Strain/sprain injuries can be caused by factors like inadequate warm-up and fatigue. These injuries involve a type of dysfunction characterized by damage to muscles, tendons, or ligaments.
Step-by-step explanation:
A strain is the result of muscle or tendon tearing due to overstretching, while a sprain is a ligament tear caused by excessive force on a joint. Both strains and sprains can be categorized as primary pathogenesis since they occur directly as a result of an injury. Strain/sprain injuries can occur due to underlying factors such as inadequate warm-up or insufficient muscle strength.
Fatigue can be associated with strain/sprain injuries since tired muscles are more prone to injury. These injuries involve a type of dysfunction characterized by the tearing or damage to muscles, tendons, or ligaments.
