(sample) GD: Bones 1 (First Timers)

The neck of the horse has about this many bones:

To send one pound of supplies to the ISS costs about: 

The DNA makes it so different areas of bone gets thicker as it is stressed more.

Thick lumbar vertebrae are critical for your neck’s support when you jump!

You can see clumps of DNA with a light microscope but you cannot see the individual rungs of DNA.  (Think!)

How many nerves are in your spinal cord?

The “body” of the vertebrae is the round, solid part of the vertebrae.

What animal has a skull that looks like the skull below?

The pores in the skull below make it lighter so the animal doesn’t have such a heavy skull. These are called sinuses.

The skeleton below is of:

These wide, flat “boxes” are solar panels for the Apollo Moon Lander.

One of the blue-throated hummingbird’s migrations includes an astonishing 500-mile trek across the Gulf of Mexico

A real problem with being in Space for any extended period of time is that your bones begin to shrink in width because of the lack of stress on them. Because of this, astronauts visiting the ISS exercise almost every day.

We have 7 neck vertebrae. Giraffes have long necks but only have twice as many vertebrae as we do.

These bones are the cervical vertebrae of the neck.

We completely understand how bones are formed in the womb of a pregnant woman.

How many bones are in an adult person’s body?

The bony part of the vertebrae which stick out toward the back are called spinous processes. These are the bumps you feel when you rub your hand down a person’s back

These woven white bands are called discs. They cushion the pounding of each vertebrae against its neighbors.

Your backbone, your spine, has 255 discs.

The Nucleus Pulposus (below) swells with water like an airbag in a car fills with air. This helps the discs to cushion the shock of the day-by-day pounding of your vertebrae on each other.

Individual vertebrae curve inward on the sides to give them extra strength.

Back injuries are caused because the human backbone is poorly designed.

You can re-injure back as you sleep because your brain often flips you over as you sleep if you sleep on your

Exercising daily helps you feel better because it releases endorphins, brings clear thinking, far better health, and pleasant fitness.

What is this?

The hole in each of these vertebrae is for the blood supply going to the whale’s head.

A whale’s spinal cord may have as many as 100 billion nerves.

The whale’s ribs are called floating ribs because they do not connect to a bone on the underside.

The pink parts of this diagram are cartilage that connect the ribs to the clavicle.

We have 4 floating ribs.

This (below) is the car piece of the turtle.

The spinal cord of the turtle is connected to its shell.

This skull is the skull of a river otter.

Look carefully at the eye bones of the creature above. Each one is made of several bones that have grown together.

Eye bones are called orbital bones.

Owls can turn their necks a whopping 7/8ths of the way around. (Ask for help if you need it to answer this one.)

Arteries and veins go up through the neck into the skull area.

Owls have special “devices” to make it so doesn’t kill itself when it turns its head around.

In owls, there is roomy extra space around the neck artery which creates multiple air pockets that cushion the artery. These allow it to travel safely during twisting motions.

We have two general types of bones: compact bone (cortical bone) and trabecular bone (springy bone).

Blood is made in the spaces between the trabecular spongy bone network.

This is the feemore bone of a sauropod.

Fingernails and hair are completely dead. There is nothing at all living in them. Bone is different.

The head (the top) of the femur leg bone is trabecular spongy bone.

This is a picture of the caves where the Dead Sea Scrolls were found.

The bones around the human ear are compact bone. There is no spongy bone near the ear.

The cochlea of the ear is shaped like 3 bent tubes in the shapes of upside-down U’s.

The orbital bone around the eye has some compact bone on its edges.

The orbital bone of the human eye fits around the eye very tightly.
