Root Explanation

Troponin is derived from the Greek word 'tropos' (meaning turn or change) and 'tonos' (meaning tension or tone). Troponin is a protein complex that plays a crucial role in muscle contraction by regulating the interaction between actin and myosin, thus affecting muscle tone and contraction dynamics.

Memory Tip

Think of 'turning' ('tropos') and 'tension' ('tonos') to remember that troponin is involved in regulating muscle contraction and tone.
