Web8 jul. 2011 · A muscle contraction represents shortening of the myofilaments with individual cells that comprise the muscle. A tiny tube-like network called the sarcoplasmic reticulum, or SR, surrounds each myofilament. In a relaxed state, the SR contains a high concentration of calcium. The SR controls muscle contraction and relaxation by regulating calcium ... WebActinide Contraction. The atomic size/ ionic radii of tri positive actinides ions decrease steadily from Th to Lw due to increasing nuclear charge and electrons entering the inner (n-2) f orbital. This gradual decrease in the size with an increasing atomic number is called actinide contraction like lanthanide contraction.
