Question

Which of the following is important for muscle contraction and nerve impulse transmission-

• A. $C{a}^{++}$ and $M{g}^{++}$ ions
• B. $F{e}^{2+}$ ions
• C. $C{a}^{2+}$ Ions
• D. $M{g}^{++}$ ions

Answer 1

The correct option is A $C{a}^{++}$ and $M{g}^{++}$ ions

Calcium is important to the transmission of nerve impulses to the muscle fiber via its neurotransmitter triggering release at the junction between the nerves. Inside the muscle, calcium facilitates the interaction between actin and myosin during contractions.
Magnesium also plays a role in regulating muscle contractions. It acts as a natural calcium blocker to help muscles relax. It plays an essential role in nerve impulse transmission and conduction.

So, the correct answer is- option b.
