Regions of the Bone

Question 1

What are the different regions of the bone?

Question 2

Diaphysis

Answer 2

cylindrical shaft of the bone

Question 3

Epiphysis

Answer 3

ends of the bone; larger to strengthen joints

-increases surface area for articulation and tendon/ligament attachments

Question 4

Regions within the Epiphysis

Answer 4

Proximal Epiphysis
Distal Epiphysis

Question 5

Proximal Epiphysis

Answer 5

proximal end of the bone

Question 6

Distal Epiphysis

Answer 6

distal end of the bone

Question 7

Metaphysis

Answer 7

is the region between diaphysis and epiphysis

Question 8

Regions within Metaphysis

Answer 8

Epiphyseal Plate
Epiphyseal Line

Question 9

Epiphysial Plate vs Epiphyseal Line

Answer 9

Epi plate - made of hyaline cartilage to make the bone longer (growing in height)
Epi line - remnant of epiphyseal plate in adults (once adults; no more hyaline for growth)

Question 10

What is Articular Cartilage?

Answer 10

Hyaline cartilage covering the epiphysis to reduce friction and absorb shock

Question 11

What is the Medullar Cavity?

Answer 11

hollow space within diaphysisW

Question 12

What can be found in the medullary cavity>

Answer 12

RDM in children
YBM in adults

Question 13

What does the Endosteum cover? what does it contain?

Answer 13

• it covers the internal surface of the bone
• contains osteoprogenitor cells, osteoblasts, and osteoclasts for bone growth and remodeling

location:
medullary cavity

Question 14

What does the Periosteum cover, protect, and contain? What are its continents for?

Answer 14

-covers the outer surface of the bone; except those covered by articulate cartilage
-protects bone anchors, blood vessels, and nerves to bone
-contains osteoprogenitor cells and osteoblast; for growth and repair
