A 42-year-old man presents to the emergency department with severe muscle pain and weakness after intense physical activity. Blood tests reveal a markedly elevated level of creatine phosphokinase (CPK). CPK is an enzyme found predominantly in skeletal muscle, heart muscle, and brain tissue. When muscle cells are damaged, CPK leaks into the bloodstream, causing elevated serum levels. Elevated CPK is commonly used as a biomarker to detect muscle injury, myocardial infarction, or other conditions involving muscle breakdown. Question:An increased blood concentration of creatine phosphokinase (CPK) most likely indicates:

Aponeuroses are broad, flat sheets of dense fibrous connective tissue that connect muscles to bones or to other muscles. Unlike tendons, which are cord-like structures, aponeuroses provide a wide area of attachment and help distribute muscle force across a larger surface. They are commonly found in areas requiring strong but flexible support, such as the abdominal wall and the scalp. Question:Which of the following best describes the primary function of an aponeurosis?
