axons

- conduct action potentials away from the cell body

elastic cartilage

-forms the pinna of the ear -allows structures to stretch then return to original shape

Fibro-cartilage

-found in inter-vertebral discs -absorbs compressive forces in the spine

hyaline cartilage

-lines surfaces and movable joints -provides a low friction surface -holds open passages so we can breath
