GD: Bones 5 (First Timers)

The strongest and longest bone in your body is the:

The two bones of your forearm arm are the ulna and radius. The bone of your upper arm is the homerun.

The wide bone of your pelvis that some of your femur muscles attach to is the:

Bone fibers are organized in directions to make the bones stronger.

Trabeculae are built to strengthen your bones to handle stresses better. “Trab” comes from the Latin word which means ‘beam” or “timber”.

The skull has spongy trabecular bone sandwiched between compact bone.

Plane wings have “ribs”. Plane wing “ribs“ might be named after our ribs.

The head of a bird bone (the top of it) may have dense spongy bone in it.

The woodpecker has dense, strong trabeculae in its skull like a hawk has in its wings. But the woodpecker’s are even stronger. These help the bird survive its 1200 head-slams a day.

The picture below is a good example of “trabs in trabs” (trabecular-type bracing in trabecular-type bracing).

Cross members in bridges, cranes, gates, roofs of buildings and toilet plungers often have “trabecular design”.

Built in 1889 for the World’s Fair in Paris, the 1063-foot Eiffel tower is a stunning example of using crossmembers and bracing of all kinds to keep a structure standing.

There are pictures in this article of bracing in buildings in Taiwan that combine arches and bracing.

Some Roman aqueducts were built with no mortar at all yet are still standing today after 1000 years!

Taiwan, Japan, and the Philippines are all islands more than 1000 miles off the coast of Hawaii.

House roof trusses use chewing gum to hold them together.

The keel of a bird is in the center of its foot. The flight muscles of the wings grow into it.

Which has the smaller keel in relation to its body size?

Steamboats have large keels because it helps them negotiate tight turns.

We have a flat sternum.

Your pectoral muscles are connected to your sternum.

“Bone Cliffs” provide more surface area for muscle to attach.

The clavicle’s “bone cliff” of our shoulder blade gives the shoulder muscle greater surface area to attach to.

The pectoral muscle attaches to the clavicle in a wide band.

The supracoracoideus pulls the bird foot up with an interesting pulley system.

The pectoralis muscle (pec muscle) attaches to the keel. It pulls the wing down with a powerful stroke.

Flying birds have a sternum that is nearly equal in width and height. Ostriches don’t have a keeled sternum.

Osteoporosis is a malfunction of the brain. It tends to affect more men than women.

Osteoporosis affects the wrist, the hip and the vertebrae a lot.

Osteoporosis affects the wrist, the hip and the vertebrae mostly because these areas are high in the amount of trabecular bone?

Osteoporosis affects trabecular bone greatly. It makes each of these “struts” thinner and more porous.

The image below is showing that osteoporosis can happen in the lumbar vertebrae and the head of the clavicle.

The ribs connect to the clavicle.

The sternum (the flat bone in the middle of your chest) only runs partly down the front of your chest because you need room for your intestine to expand.

Piezoelectricity is a type of electricity generated by squeezing an object like a crystal.

It was thought that the osteocytes read the fluid pressures in the canaliculi.

Up to about how many “caves” connect to each buried osteocyte cell?

Peter Curie, the brother of Mary Curie, worked on borax experiments in the early 1600’s. He and his sister experimented with the static electricity generated by squeezing logs filled with sargasso termites.

The twisting motion of a tennis serve causes unique stresses on the tennis player’s serving arm. The humerus arm bone of their serving arm is generally stronger than the arm that doesn’t serve the tennis balls.

Have bone designs ever been compared with the structure of the Eiffel Tower?

The six-foot mantis shrimp hits so fast that it causes a spark of light because of the cavitation caused.

The mantis punch creates cavitation where a low pressure bubble is formed that crashes inward.

The mantis shrimp’s claw is uniquely designed on the nano-level so it doesn’t destroy itself with its incredible force.

An ant’s exoskeleton is made of re-formed sugar. The sugar-collagen is skillfully woven in the exoskeleton so it is both lightweight and strong! (Read this carefully!!)

The parathyroid glands are watermelon-sized glands located on the back side of the thyroid. These indispensable glands monitor the calcium levels of the blood.

When the parathyroid glands in the neck detect low levels of calcium in the blood, molecules are released and osteocyte cells in bones cause more calcium to be released

The rice-sized parathyroid glands are on the back side of the thyroid. These are actually located around your windpipe, just below your Adam’s apple.

Richard Owen loved studying bird songs. He named the dinosaurs. He is seen in the picture here with the king-sized 500-pound elephant bird!

Sir Richard Owen named the dinosaurs. He is the first person to identify the parathyroid glands. He found large ones on dead Rhinos

The moon is like a 2000-mile-across nightlight. The sun is an 860,000-mile across heater.
