Skeletal System

Today we are going to talk more about Bones

Did you know,
Babies have more bones than Adults?!?

​why do we need our bones

Multiple Choice

Take a Guess: Where bones meet they form ___________.

• cartilage

• joints

• ligaments

• tendons

Multiple Choice

Take a Guess: How many bones are in an adult human body?

• 206

• 220

​why do we need our bones

We need our bones for PROTECTION

​Bones protect your internal organs

​ON YOUR NOTES:

The skeletal system provides bony protection for soft, internal organs. The skull protects the brain; the thorax (sternum, rib cage, and spine) protects the heart, lungs, and other organs.

Your Body has LOTS of bones that all have slightly different functions

The stirrup bone, also called the stapes, is in the ear. It is the smallest bone in the human body.

Multiple Choice

Where is the tiniest bone in the body?

• ear

• hand

• toes

Bones ALSO provide STORAGE

​Your bones store important materials

​ON YOUR NOTES:

Bones store materials such as fat, calcium, and other minerals (like phosphorus) for later use.

Some text here about the topic of discussion

• Fat-stored in the yellow bone marrow of long bones

• Calcium-important for blood clotting, helping muscles contract, and regulating your heart beat

• Phosphorus-​helps the body store and use energy, helps reduce muscle pain after working out

Slide 10

Multiple Choice

What material IS NOT stored in your bones?

• phosphorus

• calcium

• Vitamin D

• fat

Multiple Choice

Why is calcium important? READ ALL THE CHOICES CAREFULLY before answering.

• helps regulate your heart beat

• helps your muscles contract

• helps your blood clot

• ALL OF THESE

Open Ended

What foods do you know that contain calcium?

What have you learned about the skeletal system so far?

SUPPLY

​Blood Cells are made in your bone marrow

​ON YOUR NOTES:

Larger bones of the skeletal system contain bone marrow. Red marrow is responsible for production of red blood cells that are responsible for carrying oxygen to body tissues. White blood cells are also produced that are important for the body's immune system.

Slide 15

Multiple Choice

Why are red blood cells important?

• They fight disease

• They carry oxygen to all your body cells

• They help repair tissues

• They support your organs

Multiple Choice

What types of cells are produced in your bone marrow?

• blood cells

• epithelial cells

• muscle cells

• nerve cells

Bones provide SHAPE & SUPPORT

​ON YOUR NOTES:

The skeletal system provides a framework and attachment points for muscles, tendons, ligaments, skin and organs. Bones such as the femur in the legs bear the weight of the upper body. The spinal column makes the body straight and supports the head.

​Quizizz Slide 19

Multiple Choice

Ligaments attach muscles to bone.

• True

• False

Multiple Choice

Which bone(s) helps your body stand up straight and supports your head?

• femur

• skull

• spinal column

• tendons

MOVEMENT

Without your bones and muscles you could not move your body

The skeletal system provides a framework for muscles to attach. When they contract they pull on the bones of the skeleton, which act like levers to create movement. Leg bones come together at the knee to form a hinge joint that enables the knee to move back and forth. The hip has a ball and socket joint that allows for movement in multiple directions.
