●● Where does the word skeletal come from?
Answer: A Greek word meaning dried up body
●● How many bones in the body?
Answer: 206
●● How are the bones of the skeletal system arranged?
Answer: Arranged to provide a framework for our bodies
●● What are the primary functions of the skeletal system?
Answer: - Support the weight of the body
- support and protect the soft body organs
- storing minerals such as calcium and phosphorus
- regulation of plasma calcium
- red bone marrow producing blood cells
●● What reflects the bones function?
,Answer: The size and shape
●● Long bones
Answer: longer than they are wide; found in the arms, forearms, palms,
fingers, thighs, and legs
●● Short bones
Answer: Shaped like cubes; found primarily at the wrists and ankles

Answer: Layer of bone tissue having many small spaces and found just
inside the layer of compact bone.
●● Haversian system
Answer: Central canals surrounded by osteons; contain the blood vessels
and nerves that serve the bone

Answer: shaft of a long bone
●● Epiphysis
Answer: Enlarged ends of the long bone; covered in cartilage
●● Epiphyseal disc
Answer: growth plate
●● Medullary cavity
Answer: hollow region of the diaphysis; filled with yellow marrow (fat)
●● Periosteum
Answer: Tough, fibrous connective tissue membrane that covers the
outside of the diaphysis; protects the bone
●● Articular cartilage
Answer: Found on the outer surface of the epiphysis; forms smooth,
