## Step1<br />The first statement is about the structure of muscles. Muscles are indeed composed of bundles of muscle fibers held together by connective tissue. This is a true statement.<br /><br />## Step2<br />The second statement is about the behavior of muscles during contraction. When muscles contract, they actually become shorter and thicker, not longer and thinner. This statement is false.<br /><br />## Step3<br />The third statement is about the nature of muscle function. If a muscle functions without conscious thought or control, it is called involuntary, not voluntary. This statement is false.<br /><br />## Step4<br />The fourth statement is about the attachment of muscles to bones. When a muscle attaches to a bone, the end that does not move is indeed called the origin. This statement is true.<br /><br />## Step5<br />The fifth statement is about the state of muscles when not in use. Muscles are indeed partially contracted at all times even when not in use. This statement is true.<br /><br />## Step6<br />The sixth statement is about muscle atrophy. Muscles do not atrophy when they are exercised to the point of pain. Instead, they atrophy when they are not used or when they are injured. This statement is false.<br /><br />## Step7<br />The seventh statement is about foot drop. Foot drop is indeed a common contracture. This statement is true.<br /><br />## Step8<br />The eighth statement is about the role of intercostal muscles in breathing. The intercostal muscles are indeed important for breathing. This statement is true.<br /><br />## Step9<br />The ninth statement is about muscular dystrophy. Muscular dystrophy is a chronic condition in which nerve impulses are not properly transmitted to the muscles. This statement is true.<br /><br />## Step10<br />The tenth statement is about muscle spasms. Muscle spasms are indeed sudden, painful, involuntary muscle contractions. This statement is true.<br /><br />## Step11<br />The eleventh statement is about pronation. Pronation is not an overstretching of or injury to a muscle. Instead, it is a rotational movement of a body part. This statement is false.
