- stores fats and minerals
5 classifications of bones
Short, long, irregular, sesamoid, flat
Cylindrical shaft of a long bone
Diaphysis

Epiphysis
Where the epiphysis and diaphysis meet
Metaphysis (epiphyseal line)
Centre cavity of diaphysis
Medullary cavity
Fills the medullary cavity
Yellow bone marrow
Connective tissue sheath around diaphysis, considered bone’s life support system
Periosteum
Vascular channels that run longitudinally in compact bone
Haversian canals
Vascular channels that run horizontally in compact bone

Diarthroses
6 types of synovial joints

These 2 synovial joints are monoaxial joints
Hinge and pivot
These 2 synovial joints are biaxial
Ellipsoidal and saddle
These 2 synovial joints are multiaxial
Gliding and ball and socket
