Question	Answer
What do you call the blood cell formation?	Hematopoiesis
What are the 2 basic types of osseus tissue?	Compact bone Spongy Bone
What are the shapes of the Bone?	Flat,Long,Short and Irregular
These are the bones enclose with tendons	Sesamoid Bone
What structure that attaches Periostem to the Bone?	Sharpey's Fibers
Tough,Ropelike protein	Collagen
Large molecules consisting of many polysaccharide attaching to and encircling core proteins.	Proteoglycans
Most of the mineral in bone is in the form of calcium phosphate crystals called?	Hydroxyapatite
This area where the marrow located.	Medullary Cavity
Yellow marrow compost of what tissue?	Adipose Tissue
It consist of blood-forming cells and is the only site of bone formation in adults.	Red Marrow
It is a dense connective tissue that covered the outer surface of bone.	Periosteum.
It is the surface of the medullary cavity is lined with a thinner connective tissue membrane.	Endosteum
The periosteum and endosteum contain __________ which function in the formation of bone,as well as in the repair and remodeling of bone.	Osteoblast
When osteoblast become surrounded by matric they are referred to as ________.	osteocytes
This present and contribute to bone repair and remodelling by removing existing bone called bone reabsorption.	Osteoclast
This is where the bone grows/multiply seen in Young growing bone.	Epiphyseal Plate
Seen in adults Bone it is the barrier when the bones stops growing.	Epiphyseal line
Osteoblast forms _________ which crystallize on the cartilage framework.	Calcium phosphate
Osteoclast secrete both __________ and _______ mixture that dissolve the calcium phosphate released by osteoblast.	Collagen-Digesting and Acidic Hydrogen-ion
It is a process that self-destruct before they can do any more damage.	Apoptosis
Spongy bone only contains ______ and _________ containing nerves,blood vessels,bone marrow.	Trabeculae and open spaces
Another canal that connects the blood vessels from compact bone to spongy bone. Perpendicular to central canal.	Volkmann's Canal
It is the hormones released activated when the calcium-ion is low,osteoclast will be activated. Osteoclast break down bone and release calcium ion to the blood.	Parathyroid Hormones (PTH)
It is released when calcium is high and prompts the calcium storage to bones by osteoblast. When it is released the osteoblast process to build bones.	Hypercalcemia ( high blood calcium levels )
It is a fracture common on children.	Greenstick Fracture
What are the steps in Bone Repairing?	Hematoma Formation Callus Formation Callus Ossification Bone remodeling
It is the only Bone that does not articulate with another bone. Serves as a movable base of the tongue.	Hyoid bone
The bones are seperated by a fluid-filled Joint Cavity. These cavity contains a bit of viscous egg-white-like _____________ that acts like grease on a hinge.	Synovial fluid
articulating surfaces of two bones united by fibrous connective tissue. They have no joint cavity and exhibit liitle or no movements.	Fibrous Joints
