TOPIC: Locomotion
Aim: Explain the life process of locomotion and
bone structure.
Do Now: Label the endocrine system diagram in
your notes.

is?

Your Femur (thigh bone)
is stronger than concrete.
• It’s about 1/4 of your
height.
• Bone is stronger, inch
for inch than the steel
used in skyscrapers.
The jawbone is the hardest in
the human body.
Locomotion • Movement of the
body or body parts
from 1 place to
another
Skeletal 1. Movement
System
functions
2. Protects organs & tissues
3. Gives body shape &
support
4. Produces blood cells
5. Stores calcium and phosphorus

Bone
1. Compact bone =
Structure outside of bone
• Ca & P (hardness
& strength)
2. Spongy bone = ends of long
bones for added strength
3. Marrow = inside of bone
• 2 types:
–Yellow marrow = fat cells
–Red marrow = produces
blood cells
4. Periosteum = Tough outer
membrane
• Blood vessels and nerves
• Bone-forming cells
5. Canals = blood vessels and nerves
Let’s summarize…
1. Explain the process of
locomotion.
2. Explain some functions of the
skeletal system.
3. Explain some parts of the bones.
Determine if the following statements are true or
false. If false, change the underlined word to
make the correction.
1. Blood vessels and nerves travel through
bone canals.
2. Yellow marrow found inside bones
produces blood cells.
3. The end of long bones contains the
periosteum.
4. Compact bone is found on the outside of
bones.
5. Lipids give bone hardness and strength.
6. Kidney transplants are used to treat
leukemia.
7. The skeletal system protects your organs
and tissues.
8. The life process of transport allows your
body to move from place to place.
9. Spongy bone is found at the end of long
bones.
10. The tough outer membrane is known as
compact bone.
