Spinal vertebrae, bones of pelvis, several skull bones

Question 14

Sesamoid bones - location

Answer 14

small flat bones that develop inside tendons and most commonly located near joints at the knees, hands, feet. (patella)

Question 15

Question 21

Bone Functions? 7

Answer 21

Support, Protection, movement,
mineral and growth factor storage, triglyceride storage
blood cell formation, , hormone production

Question 22

Function - Support

Answer 22

Bones form a framework that support the body and cradles soft organs

Question 23

Function - Protection

Answer 23

Skull protects brain, vertebrae surround spinal cord, rib cage protects vital organs of thorax

Question 24

Function - Movement

Answer 24

Muscle uses bone as levers to move the body

Question 25

Function - Mineral and growth factor storage

Answer 25

Reservoir for minerals, notably calcium and phosphate and growth factors

Question 26

Function - Blood cell formation

Answer 26

Hematopoiesis occurs in red marrow

Question 27

Function - Triglyceride storage

Answer 27

Fat is stored in bone cavitites (yellow marrow)

Question 28

Function - Hormone production

Answer 28

Produce osteocalcin (hormone which regulates bone formation, guards against obesity, diabetes, glucose intolerance)

Question 29

Wormian/sutural - characteristics

Answer 29

small (a grain of sand to size of quarter), flat irregularly shaped bones

Question 30

Skeleton?

Answer 30

Very dynamic! Bone, cartilage, ligaments and other ct that stabilizes or connects to bone

Question 31
