Q

What are Flat bones?

A

Bones that are thin, flattened, and usually curved; contain two thin layers of compact bone sandwiched between a layer of spongy bone.

Q

What is a Epiphyses?

16
Q

What does Articular Cartilage do?

A

It covers the external surface of the epiphyses and provides a smooth, slippery surface that decreases frcition at joint surfaces

17
Q

What is the Epiphyseal line?

A

A thin line of bony tissue spanning the epiphysis that looks a bit different from the rest of the bone in that area.

18
Q

What is a Epiphyseal plate?

A

A flat plate of hyaline carilage seen in young growing bone. (causes the lengthwise growth of a long bone)

19
Q

Where is Yellow Marrow Cavity found and what is it?

A

Found in the Medullary cavity. It is a cavity of a shaft; primarily a storage area for adipose (fat) tissue.

20
Q

What is Red blood marrow and where is it found?

A

It is found in the cavities of spongy bone of flat and the epiphyses of some long bones; It is where red blood cells are produced

21
Q

What are bone markings?

A

Bumps, holes, and ridges located on the surface of bones (reveal where muscles, tendons and ligaments were attatched and where blood vessels and nerves passed)

22
Q

How many categories of bone markings are there and what are the names?

A
  1. Projections or Processes (grow out from the bone)
  2. Depressions or Cavities (indentations in the bone)
23
Q

What is Osteocytes?

A

Mature bone cells

24
Q

What are Osteoblasts?

A

Bone building cells

25
Q

What are osteoclasts?

A

Bone destroying cells

26
Q

What is a Lacunae?

A

tiny cavities in bones or cartilage where osteocytes are found

27
Q

What is a Lamellae?

A

Concentric circles in which the Lacunae are arranged

28
Q

What are Central (Haversian) canals and what is their function?

A

Canals in bones that are surrounded by lamellae and run lengthwise through the body matrix, carrying blood vessels and nerves to all aread of the bone

29
Q

What is a Haversian System or osteon?

A

Each complex consisting of central canal and matrix rings

30
Q

Function of Canaliculi and what are they?

A

Tiny bone canals that form a transportation system that connects all the bone cells to the nutrient supply through the hard bone matrix

31
Q

What does the the Perforating (Volksman’s) canals do?

A

the communication pathway from the outside of the bone to its interior

32
Q

What gives hardness to the bone?

A

Calcium salts deposited in the matrix

33
Q

What gives the bone flexibilty and strength?

A

Organic parts such as the collage fibers
