This word part means "bone"
Osteo-

What is the name/label given to each end of a long bone?
Epiphysis
100
What is the name of bone cells
Osteocytes
100
Name 3 functions of the skeletal system:
Support
Protection
Movement
Storage
Manufacturing
100
This is the outer layer of bones (where muscles attach)
Periosteum
200
This word part means "growth"
-physis
200
Spongy Bone
200
This part of bones is where fat is stored (and has a higher percentage in adults)
Yellow Bone Marrow
200
Provides flexibility and tensile strength to bones
The osteoid portion (organic composition of bones)
I would also accept Collagen because that is the primary component responsible for flexibility.
200
This cell type breaks down bone
Osteoclasts
300
This word part means "little neck"
Trabecul-
300
Osteon
300
How are bones classified?
Based on SHAPE
(flat, long, short, irregular, sesamoid)
300
If you haven’t been eating your vegetables or drinking milk, the calcium in your blood will be quite low. What hormone will break down your bone to put calcium back into your blood?
PTH
300
This structure keeps bone cells connected and supplied with nutrients
Canaliculi
400
What is an osteoblast
A bone cell that builds bone (secretes bone matrix)
More literally translated as "immature/ germ cell that is found in bone"
400
Identify BOTH terms for this structure:
Central canal OR Haversian Canal
400
Spongy bone is a lattice made up of __________ shown below:
Trabeculae
400
As adults age, this covering on the ends of their bones deteriorates, causing bones to make grinding noises as they move past each other…
Articular cartilage
400
Process of incorporating minerals, calcium, and cartilage into hardened bones
Ossification
500
Your grandmother has recently suffered an intracranial hematoma. What is a hematoma and in which part of the body would it be found?
A mass of blood found in the skull
(Hematoma is a localized collection of blood outside the blood vessels that forms as a result of trauma or injury - stage one in healing after a fracture)
(Intra - cranial meaning within the skull)
500
Identify the letter AND name of location where bones grow in length during childhood and adolescence?
E - the epiphyseal line
(In children/teens still growing this is called the epiphyseal plate - once you are done growing a line remains separating the epiphysis from the metaphysis)
500
The knee cap is an example of this type of bone
Sesamoid
500
Which part of the bone matrix gives it compressive strength?
Hydroxyapatite
(This is a type of calcium phosphate crystal which provides hardness and rigidity, allowing bones to withstand compression)
500
Describe the composition and percentages of what makes up the organic and inorganic parts of bone.
35% Organic: Collagen and ground substance
65% Inorganic: Mineral salts/calcium
