Anatomy 260 chapter 5: Skeletal
System Test Questions with Correct
Answers.
The Skeletal System is Made of: - Answer Skeletal Bones
Cartilage
Ligaments (Connect Bone to Bone)
Connective tissues to stabilize the Skeleton
Functions of the Skeletal System: - Answer Support (Body and Organs)
Protection (to Internal Organs)
Storage of Minerals
Blood Cell Production
Leverage
What is Leverage? - Answer Muscles pull on the bones to produce movement.
What dose Red Bone Marrow Produce? - Answer Erythrocytes, Leukocytes and Platelets.
Bone Cells? - Answer Contribute to Only 2% of the bone mass.
Bone Matrix? - Answer Consists largely of Crystals of Hydroxyapatite (Calcium phosphate)
Accounting for almost 2/3 of the weight of bone. The remaining 1/3 is dominated by collagen
fibers and small amount of calcium salts. Collagen and Hydroxyapatite make bone tissue
extremely strong.
Osteocytes - Answer -Mature Bone Cells, Completely surrounded by hard bone matrix.
-Maintain the protein and minerals content of the matrix.
Osteoblast - Answer -Immature bone forming cells, can convert to osteocytes
-By the process of osteogenesis, osteoblast synthesize osteoid, which is bone matrix prior to its
, Osteoprogenitor Cell - Answer -Differentiate to from new osteoblast
-Heavily Involved in the repair of bones after a break
What are the Two types of Osseous Tissue? - Answer Compact Bone (Dense Bone)
Spongy Bone (Trabecular Bone)
Compact Bone - Answer Also Known as Dense Bone
-Forms the walls of bone outlining the medullary cavity
- Makes up the dense, solid portion of bone.
Spongy Bone - Answer Also Known as Trabecular Bone
-Trabeculae from an open network of plate
- Creates the lightweight nature of Bones
Lamellae - Answer A Layer of calcified matrix, Bone structure is determined by hormones, diet,
mechanical stress, muscle attachments.
Epiphysis - Answer Each End of the long bones
Diaphysis - Answer Shaft of the long bones
Metaphysis - Answer Narrow growth zone between the Epiphysis and the Diaphysis.
Osteon - Answer Basic unit of skeletal bones:
Consists of:
-Central Canal
-Canaliculi
-Osteocytes
-Lacunae
-Lamellae (Layers)
