What is the relationship between a cell's structure and its function?

• The function of the cell builds the cell structure.
• The structure of the cell helps the cell carry out its function.
• The function of the cell helps it carry out the cell structure.
• The structure and function of the cell are not related.

What is the function of nerve cells in the body?

• They carry oxygen throughout the body.
• They transport nutrients to various parts of the body and carries waste products away.
• They make long connections to transmit signals to and from the brain.
• They aid in responding to diseases and infection.

How do nerves aid in the healing process?

• They carry crucial cells that help fight off disease and infection.
• They send key components that cells need like nutrients, water & oxygen.
• They detect pain and send signals to your brain about stimuli they receive.
• They help maintain a rigid shape and support our cells.

The structure of a nerve cell can be seen in the image below. How does the shape or structure of a nerve cell help it carry out its function in the body?

• Its round, flat flexible shape allows it to move freely through the body to transport oxygen.
• Its sticky, stretchy tentacle-like arms allow them to stick together on and around a damaged area.
• The strong rigid structure provides a rigid internal framework that gives shape & support to our body
• The long branching arms allow them to make long connections and send signals throughout the body.
