Epiphysis
Located on the end of the shaft, and is usually larger in diameter than the shaft
Epiphyseal plate

Type of connective tissue covering bone;
Contains blood vessels, lymphatic vessels, nerves, osteoblasts, osteoclasts, and stem cells that develop into various bone cells
Osteoblasts
Make bone
Osteoclasts
Degrade bone
Medullary or marrow cavity

Contains fatty, yellow marrow in adults, which functions in fat storage
