Stronger contraction of a muscle requires recruitment of more motor units. There are no sarcomeres. When these arteries relax, more blood flow to the skin which increases heat loss. Differentiate smooth, cardiac and skeletal muscle based on their microstructure. Myofibrils are composed of individual: sarcomeres striations myofilaments fascicles 2. Sarcomeres contract but myofilaments do not. Finally, immerse yourself in the process of the sliding filament theory by interacting with the contractile proteins of a sarcomere.
