NASM 2024 Practice Test Questions with Correct Answers A-Band - Answer-The region of the sarcomere where myosin filaments are predominantly seen with minor overlap of the actin filaments Abduction - Answer-A movement in the frontal plane away from the midline of the body Acceleration - Answer-When a muscle exerts more force than is being placed on it, the muscle will shorten. Also known as concentric contraction or force production Acidosis - Answer-The accumulation of excessive hydro...

1. Myocyte Muscle cell 2. Sarcolemma Plasma membrane of myocyte 3. Sarcoplasm Cytoplasm of myocyte 4. Myofibril Tightly packed filament bundles found within skeletal muscle fibers. Contractional unit of a muscle cell. 5. Sarcoplasmic reticulum Site of calcium storage in a muscle cell. Surrounds the myofibrils 6. Transverse tubules (T-tubule) Inward extensions of the sarcolemma that dive into the muscle fiber and surround each myofibril to form a tunnel- like network within the musc...

AMP 1 test nervous system & muscular Question and answers 2023 verified to pass skeletal muscle - correct answer is responsible for voluntary movement of the body. They are made up of muscle fibers with connective tissue wrappings Epimysium - correct answer the dense, fibrous connective tissue surrounding the entire muscle. At the ends of the muscle it is continuous with the tendons and periosteum of the bone. Perimysium - correct answer The connective tissue that surround bundle...
