❥ Does calcium ion concentration in blood cause tetany in some cases? Compare fluctuation in blood calcium with tetany.

❥ How does the slipped disc affect the lower back and overall health?

❥ Describe the significance of Ca2+ ions in the contraction of muscles.​

Answer 1

❥A slipped disc can cause very sudden and severe shooting pain. If it occurs in the neck area, the pain might radiate into the arms. Slipped discs in the lumbar (lower back) region are the main cause of sciatica. Sciatica is pain that radiates down one leg and into the foot

❥Ca2+ ions play an important role in muscle contraction by creating interactions between the proteins, myosin and actin. The Ca2+ ions bind to the C component of the actin filament, which exposes the binding site for the myosin head to bind to in order to stimulate a muscle contraction.

❥ Hypocalcemia is the primary cause of tetany. Low ionized calcium levels in the extracellular fluid increase the permeability of neuronal membranes to sodium ion, causing a progressive depolarization, which increases the possibility of action potentials.

❥ Injury or weakness can cause the inner portion of the disc to protrude through the outer ring. This is known as a slipped, herniated, or prolapsed disc. This causes pain and discomfort. If the slipped disc compresses one of your spinal nerves, you may also experience numbness and pain along the affected nerve

❥ Importance of Calcium Ions. Ca2+ ions play an important role in muscle contraction by creating interactions between the proteins, myosin and actin. The Ca2+ ions bind to the C component of the actin filament, which exposes the binding site for the myosin head to bind to in order to stimulate a muscle contraction.
