True or false?
The Pelvic Outlet is an imaginary plane?

True

Osteoblasts

12

14

How many lumbar vertebrae does the human body have?

5

15

What is an example of short bones?

Carpals

16

What forms:
the anterior cranial floor
Medial orbit walls
Upper parts of the nasal septum
Sidewalks of the nasal cavity

Ethmoid bone

17

Like long bones, flat bones are covered in a periosteum and the inner spaces are lined with?

Endosteum

18

Support
Protection
Movement
Mineral storage
Hematopoiesis
Are all _______ of _______?

Functions of bone

19

What is the development of bone from the small cartilage or membrane model into adult bone?

Osteogenesis

20

What does the process of appositional growth refer to?

It occurs through the addition of osseous tissue to the outer surface of a flat bone

21

What do muscle tendon fibers interlace with?

Periosteal fibers

22

A few layers of bone matrix also run around the outer boundary of compact bone, encircling all the osteosarcoma. These layers that run along the inner circumference (along the endosteum) and outer circumference (along the periosteum) of a bone is called?

Circumferential lamellar

23

Are small cells that synthesize and secrete an organic matrix called osteoid?

Osteoblasts

24

Are giant multinucleate cells, that are responsible for the active erosion of bone minerals.

Osteoclasts

25

Collagen strands in the osteoid serve as framework for the formation of hydroxyapatite crystals, which mineralized the bone tissue. Osteogenic stem cells, found in the endosteum and lining the central canals, undergo cell division to form?

Osteoblasts

26

Formed by the fusion of serial precursor cells and contain large numbers of mitochondria and lysosomes. Erode bone by releasing hydrochloride acid (HC1) that dissolves mineral crystals and collagenase, which is an enzyme that breaks the peptide bonds in collagen proteins. The dissolved mineral ions and amino acids that result from bone erosion are reabsorbed by the bloodstream and recycling for use by fibroblasts, osteoblasts, or other cells of the body.
Responsible for the active erosion of bone minerals?

Osteoblasts

27

Are mature, nondividing osteoblasts surrounded by matrix and lying within lacunae

Osteocytes

28

Surround central ( osteoblasts or haversian) canals that run lengthwise through bone and are connected by transverse canals (Volkmann canals)

Osteoid

29

What cell organelles synthesis organic matrix substances?

Golgi apparatus and ?

30

Is composite of collagenous fibers and a mixture of protein and polysaccharides called ground substance
Chondroitin and glucosamine also

Organic matrix of bone
