The cranial bones are bones that surround and protect our brain. In infants, the cranium is composed of different separate cranial bones.
- The bone that exists as five separate bones when you are an infant is the CRANIUM.
- The major bones (bony plates) that form the cranium of an infant (newborn) are 2 frontal bones, 2 parietal bones and one (1) occipital bone.

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.
