Science Chapter 5 Lesson 1

Your bones along with the tissues that connect them, form the is called the

• muscle system

• skeletal system

• bone system

• tissue system

Your bones are made up of cells called

• axons

• tissues

• osteocytes

• marrow

All of the following are true about the skeletal system except

• Your leg and arms help you move

• Your spine supports your body and keeps it upright

• It consist of the cerebrum, cerebellum and axon

• Your ribs and skull protect your internal organs

The osteocytes are cells that are responsible for

• repair only

• growth only

• growth and repair

• bending

All of of the following are one of the four layers bones except

• outer covering

• compact bone

• soft bone

• bone marrow

What is the purpose of the outer covering of the bone?

• Give flexibility to the bone

• Carry nutrients and waste to and from the bone cells

• To form red blood cells

• Provides movement

Which layer of the bone is filled with cavities and gives flexibility to the bone

• outer bone

• compact bone

• spongy bone

• bone marrow

What is cartilage?

• Hollow space or cavity deep in the bone

• A hard thick layer

• what you see when you look at a skeleton

• connective tissue that forms part of your skeleton

Movement happens where bones meet at the

• muscle

• ligament

• tissue

• joint

What are strong bands of connective tissue that hold the bones in the movable joints together?

• ligaments

• hinge

• pivot

• cerebrum
