Bone

Activity 1.1.

● Explain the characteristics of the four types of bones.

● Identify the external and internal features of a long

bone.

● Use a microscope to compare the structure of spongy

and compact bone.

● Use diagnostic reasoning to analyze a case.

Bone’s Unique Architecture

● Bones are lightweight, flexible, and strong,

providing a frame for the body.

● Bone is living tissue with cells and protein fibers

wrapped in layers of mineral salts.

● Cells constantly remodel and replace old or

damaged bone.

● Blood vessels and nerves supply nutrients and

signals to bone cells.

● Bones can withstand stress and protect internal

organs.

● There are different types of bones.

Upon Closer Examination

1. Put on gloves.
2. Observe the long bone at your lab table.
3. Draw a diagram of the long bone in your NB.
4. Use the BioDigital to help you identify the external and

internal structures of a long bone.

1. Label the following on your diagram. Use this video to

help.

a. Spongy bone f. Yellow bone marrow

b. Blood vessel g. diaphysis

c. Compact bone h. epiphysis

d. Periosteum i. metaphysis

e. Medullary cavity

The skeleton of our arms and legs are mostly long bones. This

provides the leverage we need to move and interact with our

environment.

Take the Long Bone Quiz to test your knowledge!!

Conclusions

1. Compare the structure of compact

bone with spongy bone. Which one

weighs more? How does the

structure of different bones impact

their function? (you will need to

review the function of each type of

bone to help you)

2. Do bones have blood vessels inside of

them? Explain why/why not.

Upon Closer Examination

1. Obtain a Bone Origami Organelle

template, tape, and scissors.

1. Follow the guide to build the model long

bone using the template.

1. Label the different parts of the long bone

as you assemble it.

The skeleton of our arms and legs are mostly long bones.

This provides the leverage we need to move and interact

with our environment. To further your understanding of

long bones, create and label a model.

A Long Bone Construction

To begin your origami construction, cut the blood vessel from the Small Bone End template.

Cut out around the

fork-shaped blood

vessel.

Cut along the solid black lines, NOT the dashed lines. Fold along the dashed line.

Curl the sides, taping sides and top together.

Cut along the solid black lines. Roll lengthwise and tape to create a tube.

Cut along the solid black lines. Fold along the dashed lines.

Cut the sides, taping sides and top together.

Cut along the solid black lines. Fold sides up along the inner dashed lines. Then fold in half along the outer dashed lines.

Cut sides around, taping to the base. Tape sides together at the front.

Cut along the solid black lines. Fold sides up along the inner dashed lines. Then fold in half along the outer dashed lines.

Cut the sides around, taping to the base. Tape sides together at the front.

Bone shaft, folded before taping.

Cut along the solid black lines. Fold down sides along the dashed lines. Tape the sides lengthwise, but do not tape the flaps yet.lines.

Push the middle inward to make a central channel. Fold the flaps down & tape to the opposite side.

Slide the bone marrow into the central channel.

Slide the bone shaft over the tab of the large bone end; tape the sides and bottom.

Slide the bone shaft over the tab of the small bone end; tape the sides and bottom.

Insert the large & small spongy bone pieces into their respective bone ends.

Add the blood vessel.
