MCQ IN MEDICINE

Detailed explanation-1: -Skeletal muscle function can be studied by the use of voluntary contractions (handgrip strength) or involuntary contractions (muscle contraction in response to an electrical stimulus).

Detailed explanation-2: -Definition: A process in which force is generated within involuntary skeletal muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis.

Detailed explanation-3: -Muscular contractions can be voluntary or involuntary. The action that involvement of thoughts is a voluntary action. The brain is responsible for voluntary muscle contraction.

Detailed explanation-4: -Peripheral neuromuscular diseases are associated with many forms of involuntary muscle contractions, the most common of which is a muscle cramp that can occur in both health and disease. Muscle cramps are an involuntary and painful shortening of skeletal muscles. During cramping, muscles feel firm.
