Bone Flashcards
A connective tissue with cells and fibers embedded on a gel- like ground substance.
Cartilage
Tightly packed collagenous fibers.
Dense connective tissue
Connective tissue with cells and fibers embedded in a calcified ground substance.
Bone
Is connective tissue in which the intercellular substance is rendered hard by being impregnated with mineral salts chiefly calcium.
There are 4 types bone cells
Bone or osseous tissue
These are osteoblasts that mature and migrate into the bone.
Osteocytes
Large cells found on bone surfaces responsible for resumption of bone matrix during growth and repair
Osteoclasts
Immature bone cells found in the periosteum and endosteum
Osteoblasts
Unspecialized cells which have the ability to differentiate into osteoblasts.
Osteogenic
A layer of osteogenic cells and osteoclasts that lines the medullary cavity.
Endosteum
A dense irregular fibrous connective tissue that covers the surface of the bone not covered by the articular cartilage.
Periosteum
Also known as cortical bone, very dense tissue organized in haversian systems.
Compact bone
The marrow cavity in the center of the bone site of blood cell production or fat storage.
Medullary cavity
Also known as cancellous bone. Forms a lattice-like structure of spiked bone called trabeculae.
Spongy bone
What are two types of bone marrow?
Red= blood cell plates and most white blood cells . Yellow= mostly fat - used as energy.
Compact bone of closely packed osteons.
Haversian system
