Actually girls grow more than boys because girls develope faster and mature faster.
Skeleton muscles relay on contractions to move the bone they are attached to so it can contract and relax
Answer:
206 bones
and babies have 300 bones which then fuse together as they grow older to the 206
Explanation:
At the onset of a muscle contraction, the presence of calcium triggers the opening of the Na-K channels in the membrane. Potassium is a calcium inhibitor, so as the potassium flows out of the cell, it eventually reduces the presence of calcium. This causes the closure of the Na-K channel (negative feedback mechanism). In a hypokalemic state, the lack of sufficient K doesn't inhibit the calcium channel, and in turn doesn't properly terminate the muscle contraction at the cellular level.
