Which statement correctly describe the functions of the human skeletal system?

I. It supports the body.

II. It gives the body its shape.

III. It protects the organs in the body.

IV. It enables different parts of the body to move.

• I and IV only

• II and III only

• I, II, and III only

• I, II, III and IV

How do the skeletal and muscular system work together?

• Muscles contract and pull on bones to move.

• Bones provide energy for muscle contraction.

• Muscles provide vitamins and minerals for the bones.

• Bones transmit electrical signals for muscles to contract.

What is the function of joints in our bodies?

• Joints make blood cells.

• Joints protect our organ.

• Joints attach muscles to bones.

• Joints allow us to bend and move our bodies.

How do muscles help us move our body parts?

• Muscles supply bones with blood to move.

• Muscles attach the bones together to move.

• Muscles contract and relax to move the bones.

• Muscles produce electrical impulses that propel bones to move.

Which type of muscle can we control?

• Involuntary muscles

• skeletal muscles

• muscles in our heart

• digestive muscles

What are involuntary muscles?

• muscles that grow bigger when we exercise

• muscles attached to the bones that we feel pulling

• muscles that we can control, like when we raise our hands

• muscles in our heart and digestive organs that we cannot control

What are tendons for?

• Tendons protect soft bones in the body.

• Tendons are the part of the bone where blood cells are made.

• Tendons connect two or more bones to allow bending or folding.

• Tendons attach muscles to bones so muscles can pull the bones to move.

Which are movable joints?

• hinge joint

• fixed joint

• ball and socket

• saddle joint

This joint allows movement in all directions.

• Hinge joint

• Pivot joint

• Saddle joint

• Ball and Socket joint
