Axial
Appendicular
Head and trunk of vertebrate, central axis of human skeleton, supports the upright position and projects internal organs
Portion of the skeleton of vertebrates made up of bones that support appendages, limbs, aid in the movement of the body
How many bones in axial and the main bones
80 bones - Skull, vertebrate, rib cage, and sternum
How many bones in appendicular and the main bones
126 bones - pectoral girdle, arms, forearms, hands, pelvis, legs, feet, and ankles

functions of skeletal system
support and protection, body movement, produces blood cells, storage of minerals and fats
Long
Leverage - femur, tibia, fibula, matatarsals, humerus, ulna, radius, metacarpals, phalanges
short
Provide stability, support, while allowing for some motion - Carpals and tarsals
flat
Points of attachment of muscles; protectors of internal organs - sternum, ribs, scapulae, cranial bones
irregular
protect internal organs - vertebrae and facial bones
sesamoid
Protect tendons from compressive forces
Epiphysis
end of bone
Diaphysis
shaft
Articular Cartilage
hyaline cartilage, padding
periosteum
membrane that covers entire bone
medullary cavity
hollow chamber filled with bone marrow
