Q
How does Cartilage grow?
A
*Unlike bone, cartilage has a flexible matrix which can accommodate mitosis
Cartilage grows in two ways
- Appositional growth
- Interstitial growth
20
Q
appositional growth
A
cartilage- forming cells in the surrounding perichondrium secrete new matrix against the external face of the existing cartilage tissue
21
Q
interstitial growth
A
the lacunae bound chondrocytes divide and secrete new matrix, expanding the cartilage from within.
22
Q
when does cartilage growth end?
A
typically ends during adolescence when the skeleton stops growing
23
Q
Calcified Cartilage
A
during normal bone growth in youth and during old age cartilage can become calcified due to deposits of calcium salts- still does not become bone

79
What are the two types of bone ossification
Intramembranous and endochondral
80
Intramembranous ossification
Bone development from fibrous membrane. Used to form only flat bones like the clavicles and cranial bones
81
Endochondral ossification
Bone forms by replacing highland cartilage, forms most of the skeleton
82
What are the steps in intramembranous ossification
1. Mesenchymal cells Turn into osteoblast while migrating to the ossification centers
2. Osteoblast turn into osteocytes and they classify themselves in place
3. Bone grows into linear expansions called specials and blood vessels will grow and branch around them to support the bone tissue
4. Growth at multiple ossification centers cause enlargement and produce spongy bone, Merrill cavities and compact bone.
83
Where can you collect bone marrow for transplantation?
The flat bones of the pelvic girdle – ileum and also the sternum
84
What are the steps and endochondral ossification
1. Brown color information
2. Chondrocytes hypertrophy and creates cavities within the Cartlidge.
3. Peritoneum bud and vision – osteoblasts and blood vessels invade the center of Cartilage in the developing bone shaft to deposit osteoblasts and osteoclasts to build spongy bone.
4. Diaphysis elongation-The diaphysis in long gate using nutrients brought byParis Danielle bud and medullary cavity forms using osteoclasts in order to suppress development of bone marrow. -Secondary ossification centers form in the epiphysis of the bones
5. Epiphyseal ossification
Ossification continues in the purposes and the diaphysis when complete, only two areas of highland cartilage remain at the surface of the purposes and at the epithelial plate – secondary ossification center appears in the epiphysis above the primary ossification center
85
What is the difference between intersexual and appositional growth
Intersexual is longitudinal gross and appositional growth increases in both thickness.
86
What is interstitial Growth dependent on?
- Primary ossification center.
- Epithelial plate.
- Secondary ossification center
87
Why must the epiphyseal plate maintain constant thickness
Rate of Cartlidge growth on one side balanced by bone replacement on the other
88
Why must bone remodeling occur in the epiphysis
To keep the epiphysis is the correct size otherwise your joints were at work
89
appositional growth
- Increase in both thickness.
- Occurs throughout your life known as bone remodeling.
- Usually more building up and breaking down.
- Osteoblast/ask your class activity regulated by Osteocalcin
90
What are the supervisors of bone remodeling
Osteocytes are the supervisors of bone remodeling which go into action when they sent stress and strain or when responding to a mechanical stimuli such as running on a hard surface.
91
What happens if they ask your side detect a tiny microscopic fracture?
They will initiate the remodeling process to fix it
92
What is the osteocyte remodeling process?
- The osteocyte releases a chemical signal to the osteoblasts to go to the site.
- They secrete a collagen digestive enzyme and an acidic hydrogen ion mixture that dissolves the calcium phosphate.
- Releasing the calcium in the phosphate back into the blood- reabsorption
- The osteoclasts go through adopoisis so they do not continue breaking a bone down but before dying they activate the osteoblast to begin rebuilding the bone.
- When we exercise we are stimulate bone remodeling and this strengthening our bones.
93
Considering interstitial bone growth and development what is the role of the epiphyseal plate
To ensure that the rate of Cartlidge growth on one side is balanced by the bone replacement on the other
94
Considering interstitial bone growth and development what is the most important in organic and organic compounds
Inorganic-70% calcium phosphate
Organic – 30% collagen
95

Vitamin a is necessary for osteoblasts and osteoclasts activity
98
What is the role of vitamin C?
Vitamin C is required for collagen synthesis
99
What is the role of vitamin K?
Vitamin K is required for the activation of osteocalcin, a hormone and extracellular but Matrix needed to bind and retain calcium in the matrix
100
What hormones regulate bone growth/development

- compact bone is replaced every 10 years
108
What happens as older bone becomes more brittle
Calcium salts crystallize and they fracture easier
109
What is bone remodeling?
-Activation of PTH causes bone reabsorption so it must be balanced with the replacement which occurs from mechanical stress.
110
How do bones respond to mechanical stress
bone is responding to increasing mechanical stressed by laying down new bone matrix.
- In places with high stress, more calcium will be deposited and less taken away while places with a little stressed or better candidates for reabsorption of calcium into circulation.
- The stress you put on your bones determines where remodeling will occur.
111
What are the results of mechanical stress?
And bones with high stress there will be more calcium deposits and taking away in the opposite side for areas with low stress
112
What are the four steps and bone repair?
1. Hematoma formation – blood escapes from the broken blood vessel’s in forms a hematoma
2. Fibrocartilaginous Calais forms-Cartledge is produced to form a fibrocartilaginous callous. —Osteoblast create new bone from this Matrix.
3. Bony callus forms
4. Bone remodeling occurs over a long period of time
113
Why do bones of the upper limbs heal faster than those of the lower limbs?
The upper body has little to no wait pressing on it. Therefore the everybody has less stress than a lower body

118
Depressed fracture
Create a depression or indent in the skull
Broken bone portion is pressed in word, typical of the skull fracture
119
Greenstick fracture
Bones bend and break but not a complete break usually in children under 10 because their bones are softer and more flexible
120
Coles fracture
Break and distal radius as a result of a fall onto an outstretched hand – common break in osteoporosis patients
121
Potts fracture
Broken ankle usually distal fibula, caused by a combined abduction and external rotation from an E version force – come ankle break

134
Osteoporosis
Bone reabsorption- Pulling calcium out outpaces the deposit of calcium- bones become very porous and brittle.
135
What does osteoporosis cause

- Loss of height overtime.
- stooped posture.
-A bone fracture that occurs much more easier than expected
143
What are risk associated with osteoporosis
Your sex-Women are more likely develop osteoporosis than men
Age – the older you get the greater your risk of osteoporosis. Race – you’re at greater risk of osteoporosis if you are a white or Asian dissent.
Family history – having a parent or sibling with osteoporosis put you at greater risk, especially if your mother or father experienced a hip fracture.
Body frame size – men and women who have small body creams tend to have higher risk because they have less bone mass to draw from as age.
Hormone levels Dash is more common in people who have too much or too little of certain hormones in their bodies – sex hormones, thyroid problems, other glands
Dietary factors – osteoporosis is more likely to occur in people who have low calcium intake, eating disorders, gastrointestinal surgery.
Medications – long-term use of oral or injected corticosteroid medications or medications that help prevent seizures, gastric reflux, cancer, transplant rejection.
Medical conditions – cardiac disease, inflammatory bowel disease, kidney or liver disease, cancer, lupus, multiple myeloma, rheumatoid arthritis
Lifestyle choices-sedentary lifestyle,Excessive alcohol consumption, tobacco use.
144
How can you prevent osteoporosis
Protein-is one of the building blocks of bone and why most people get plenty of protein in their diet some do not.
Body weight – being underweight increases the chance of bone loss and fractures
Calcium Dash men and women between the ages of 18 and 50 need 1000 mg of calcium a day. This daily amount increases to 1200 mg when women turn 50 and men turn 70.
Vitamin D – improves your body’s ability to absorb calcium and improves bone help in other ways.
