Which of these processes helps in skeletal muscle relaxation after contraction?

Explanation

Option A: Motor neurons are covered with ion channels, which open in response to electrical signals from the brain. Once these ion channels are open, a series of cascading reactions allows the signal to reach the skeletal muscle cells, which ultimately results in muscle contraction. Option B: Troponin C (TnC) is the calcium-binding subunit of the muscle protein complex troponin. The binding of calcium ions to TnC triggers the contraction of vertebrate striated muscle. Option: C Calcium release from intracellular storage sites plays a central role in the excitation-contraction coupling of striated and smooth muscle cells. It is a function of Calcium in the relaxation and contraction of the muscle.
