made up of osseous tissue ( 1/3 organic and 2/3 inorganic matter)

Question 2: Red bone marrow

Answer:

located in the spaces of the spongy bone

Question 3: What type of bone is the sternum?

Answer:

flat bone

Question 4: What is the outer fibrous layer of the periosteum made of?

Answer:

Collagen

Question 5: What is the Skeletal System composed of?

Answer:

bones, cartilage and ligaments

Question 6: Organic matter of the bone

Answer:

composed of collagen and carbohydrate-protein complexes that is synthesized by osteoblasts and gives bone its flexibility

Question 7: Spongy bones consist of

Answer:

spicules, trabeculae, and red bone marrow with few to no osteons and no central canals.

Question 8: What are the different types of bone?

Answer:

flat bones, long bones, short bones and irregular bones

Question 9: Mineralization or calcification

Answer:

the hardening process of bone from cartilage.

Question 10: Osteogenesis imperfecta

Answer:

Also called brittle bone disease and is due to lack of protein or collagen in the bone

Question 11: Osteoblasts

Answer:

bone- forming, non-mitotic cells that build bone by taking the Calcium out of blood and stores it into the bone

Question 12: Where is Red marrow located?

Answer:

in Adults-skull, vertebrae, ribs, sternum, part of pelvic girdle and proximal heads of femur and humerus in children, in nearly every bone

Question 13: Bone matrix

Answer:

is a composite of two basic structural materials, ceramic and polymer

Question 14: Spicules

Answer:

slivers of bone material in the spongy bone

Question 15: Lacunae

Answer:

tiny cavities where osteocytes reside

Question 16: Bone

Answer:

Is connective tissue that consists of cells, fibers, and ground substance

Question 17: Diaphysis or shaft

Answer:

the cylinder of compact bone to provide leverage Question 18: What is the proportion of the skeleton that has compact bone and spongy bone by weight?

Answer:

3/4 of the skeleton is compact and 1/4 is spongy.

Question 19: Epiphyseal line

Answer:

in adults, the bony scar marks where the growth plate used to be

Question 20: Inorganic matter of the bone

Answer:

composed of 85% hydroxyapatite or calcium-phosphate salt, 10% calcium carbonate and other minerals such as fluoride, potassium and magnesium. This allows the bone to support the body weight.

Question 21: Cranium general feature of bone

Answer:

is a sandwich-like flat bone construction with two layers of compact bone enclosing a middle layer of spongy bone

Question 22: Periosteum

Answer:

external sheath that covers bone except where there is articular cartilage

Question 23: Osteoclasts size

Answer:

unusually large cells formed from the fusion of several stem cells, typically 3 to 4 nuclei ( may have up to 50 nuclei)

Question 24: Red marrow

Answer:

The myeloid tissue or hemopoietic tissue that produces blood cells and composed of multiple tissues arrangement

Question 25: nutrient foramina

Answer:

minute holes in the bone surface that allows blood vessels to penetrate

Question 26: Yellow marrow

Answer:

in adults, most red marrow turns into fatty yellow marrow and no longer produces blood

Question 27: Ossification or osteogenesis

Answer:

formation of bone

Question 28: What are the tendons function?

Answer:

to attach muscle to bone but considered part of the muscular system
