Long Bones 3.1.2

Question 1

Articular cartilage

Answer 1

• connective tissue on the ends of long bones
  -lets bones glide and move without friction
  (special type , supportive)

Question 2

Epiphyseal Line

Answer 2

-a line on the bone that shows where bone growth occurred
(between epiphysis and shaft of center of bone)

Question 3

Epiphysis

Answer 3

Rounded end of a long bone.
(long bone closer to truck of body, proximal epiphysis, close to origin)

Question 4

Diaphysis

Answer 4

Long hollow tube, in middle of bone.
(known as shaft, bone marrow located here, different types)

Question 5

Distal Epiphysis

Answer 5

Rounded end further from the trunk of the body.

distal = further away, distance

Question 6

Compact Bone

Answer 6

Dense connective tissue, hardened by minerals (calcium) appear solid

Question 7

Endosteum

Answer 7

Thin membrane that lines the inside of diaphysis. (inside medullary cavity)

Question 8

Medullary Cavity

Answer 8

Hollow space inside diaphysis.

Question 9

Osteocyte

Answer 9

Bone cells found within lacunae. Strength bone tissue by adding calcium/minerals to bone tissue. Monitor health and stimulate regenerations process of bones

Question 10

Osteon

Answer 10

Basic structural unit of a compact bone (Haversian system, densely packed together)

Question 11

Periosteum

Answer 11

Tough membrane that covers long bones. Contians blood vessels that connect to muscular system. Provides connection between skeletal system & other organ systems

Question 12

Red Bone Marrow

Answer 12

Tissue that produces new blood cells, in open spaces of epiphyses (bone marrow = type of issue)

Question 13

Spongy Bone

Answer 13

Fill hollow spaces in epiphyses, can be filled with red bone marrow (cancellous bone, a porous type of bone made of branching tissue)

Question 14

Yellow Bone Marrow

Answer 14

Energy Storage, within medullary cavity, mostly fat

Question 15

Lamellae

Answer 15

Calcium-containing rings around the central canal

Question 16

Lacunae

Answer 16

Dark circles, tiny opening or living bone tissue in the osteon

Question 17

Canaliculi

Answer 17

Tiny passageways, connect lacunae to other lamellae, enables nutrients to get around

Question 18

Haversian Canal

Answer 18

The center passageway of osteon, blood vessels travel
