Ch 6 Flashcards
Dynamic tissue that is always remodeling building up and breaking down
None
What are the six important functions of the skeletal system
Provide support(Framework) protection (organs) assist the body movements mineral homeostasis participate in blood cell production store triglyceride
Two major tissues of the skeletal system
Bone and cartilage
A highly vascularized connected tissue with hard mineralized extracellular matrix found in two different arrangements in body
Bone
This type of bone is good at providing protection and support it forms the diaphysis of long bones and external layer of all bones
Compact bone
This type of bone is lightweight and provide tissue support forms much of the epiphisis and he internal cavity of long bones
Spongy bone
Thin layer of hyaline cartilage that covers epiphysis of long bones
Articulate cartilage
Where is articular cartilage found
Where bones form an articular joint
What is the purpose of articular cartilage
Reduce friction
Poorly vascularized c. T. With matrix composed of chondroitin Sulfate
Cartilage
Fiber types distinguish _________from___________or________.
Hyaline fibrocartalige elastic
Tough outer sheath of dense irregular connective tissue on the outside of the bone
Periosteum
What is the inner osteogenic layer called
Osteoblasts
What direction do osteoblasts help bone grow?
Thickness NOT length
T/F osteoblasts help assist in fracture repairs
T
_______ cavity is a space within the diaphysis of long bones that contain fatty yellow bone marrow
Medullary
A membrane that line the medullary cavity
Edosteum
What is the endosteum composed of
Osteoclast osteoblasts C. T.
Osteoblasts
Bone building cells
Osteocytes
Mature osteoblast
Osteoclasts
Large bone breaking down cells
Dense irregular C. T. membrane that surrounds cartilage
Perichondrium
Cells that form cartilage
Chondrocytes
What firms capillary walls
Epithelium
Red bone marrow is found in…
Spongy bone
Yellow bone marrow is found in
Long bones
Red bone marrow =production of_______?
Blood cells
Yellow marrow adipose cells store?
Triglycerides
