A&P 1
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
