The human body
To act as the building blocks upon which the body is built, produce blood for the body, help provide the body with movement
The skeletal system
cylinder in shape longer than is wide, purpose for leverage
Long bone
Cube like shape balanced length and width, purposed for stability while allowing motion
Short bone
Thin curved, point for attachment of muscles/ protection
Flat bone
Complex shape purposed for protection
irregular shape bone
small round and imbedded in tendons purposed to protect tendons from compressive forces
Sesamoid bones
Found on the ends of bones
Epiphysis
The center part that enclosed in the epiphysis of the bones
DIaphysis
Found on the ends of bones to protect from rough interaction
Articular Cardilledge
outer membrane that cover the bone
Periosteum
hollow chamber filled with bone marrow
Medullary cavity
main purpose is to produce blood
red bone marrow
forms fat
yellow bone marrow
walls of the Diaphysis
Compact bone tissue
epiphysis and red bone marrow
spongy bone tissue
turning the hand in to prone position
Pronation
turning the hand into supine position
Supination
pointing the foot upward
Dorsiflexion
pointing the foot downward
Plantar Flexion
Pointing the heel inward towards the midline
Inversion
Pointing the heel outward/ away from the body
Eversion
pushing a body part outward
Protraction
putting something backward
Retraction
