Copy of Electricity – Video 8 – Second Timers Quiz

BONE ELECTRICITY 1: The trabecular (spongy) bone of a turkey or a person has complex reinforcing bracing in it like the bracing found in the Eiffel Tower, buildings, train trellises and house trusses. 

BONE ELECTRICITY 1: Compact (or cortical bone), the dense white bone found in places like a femur, the upper leg bone of a cow. This bone looks simple because it is simple.

BONE ELECTRICITY 1: Every BB-sized amount of compact bone is home to many granulocytes which are “imprisoned” in lacunae. 

BONE ELECTRICITY 1: There are bone tunnels that connect the imprisoned osteocytes. A water-like fluid runs through the bone tunnels giving the imprisoned osteocytes food and oxygen. 

BONE ELECTRICITY 1: The osteocytes can live to be 100 years old.

BONE ELECTRICITY 1: This fluid moves like a lazy river through a million bone tunnels in every BB-sized amount of bone. WHY? It gives these sometimes 50-year-old imprisoned osteocyte cells continual oxygen and food during their stay in their boney prison cells.

BONE ELECTRICITY 1: These tunnels of bone, weirdly enough, also serve as communication tunnels. These connect all the insides of all your bones to the life-saving rice-sized thyroid glands which are on the back side of the neck’s thyroid gland.

BONE ELECTRICITY 1: When calcium atom levels in the blood are low, the puny parathyroid glands in your neck release billions of messenger proteins into your blood. These eventually get into the millions of bone caves and then to the imprisoned osteocytes. Then the imprisoned osteocytes send out message molecules to trigger the bone-dissolving osteoclasts to begin dissolving bone and release calcium into your blood.

BONE ELECTRICITY 2: The imprisoned osteocytes also read electrical fields. You have billions of electricity-reading imprisoned bone cells throughout all your bones!  

BONE ELECTRICITY 2: The imprisoned osteocytes detect bone electrical fields that happen as the bone is put under pressure. The osteocytes send out message molecules called hormones to trigger the bone-building osteoclasts to begin laying down thicker bone material in stressed bone areas. This, for instance, is how professional tennis players get thicker bone in just the right places on their serving arm. This helps keep them from breaking the arm they serve the tennis ball with.
