Question 1

diaphysis (shaft)

Answer 1

cylinder of compact bone that provides leverage

Question 2

medullary cavity (marrow cavity)

space in the diaphysis of along bone that contains bone marrow

Question 3

epiphyses

Answer 3

enlarged ends of a long bone

Question 4

why is the epiphyses enlarged?

articular cartilage
nutrient foramina
periosteum
endosteum
epiphyseal plate (growth plate)

Question 8

articular cartilage
