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...

Function of all musclesto generate force and movement Skeletal muscles- voluntary (somatic neurons) - striated - Multi-nucleated - insertion is more distal - antagonistic muscle groups = flexor-extensor pairs - 40% of body weight Cardiac Muscle- Primarily involuntary - striated and uninucleated - spontaneous electrical activity - altered by autonimc NS and hormones - intercalated disks that connects them - desmosomes (mechanical link) - gap junctions (electronical link) - larger but less T-Tub...
