It is also known as the collar bone -- between your shoulder and neck.
Clavicle
It is known as the foot bone.
Metatarsals
This is the process of creating new bone
Ossification
This is a joint in which a ball moves within a socket so as to allow rotary motion in every direction within certain limits.
What is a ball and socket joint?
Lower arm bones on the little finger side are called as?
Ulna
It is known as the breastbone -- middle of your chest.

The top and bottom of bones:
EPIPHYSIS
Name the 2 parts of the skeletal system
Axial Skeleton
Appendicular Skeleton
How many types of bone marrow are there, and what are they called?
2 types; Red and Yellow bone marrow.
The larger bone in the bottom half of the leg is called as?
Tibia
It is the smaller bone in the bottom half of the leg.
Fibula
This part of the bone runs between the epiphysis
DIAPHYSIS
Name the 3 types of vertebrae and how many for each.
Cervical-7
Thoracic - 12
Lumbar- 5
What is arthritis? Symptoms and is it curable.
Inflammation of the joints. No, it's not curable. Red swollen joints.
How many cranial bones? Name them on your whiteboard. Spell the terms correctly.
eight cranial bones.
Frontal bone-1
Parietal bone-2
Temporal bone-2
Ethmoid bone-1
Sphenoid bone-1
Occipital bone-1
What are the four stages in bone repair?
Hematoma formation
Bone generation
Bony callus formation
Bone remodeling
How many bones in the appendicular skeletal?
126 bones
Define compact bone
The hard layer of bone tissue found under the periosteum. It provides strength and protection to bones.
How many bones in the body in total of an adult body?
206
How many facial bones of the skull?
14
Define hematoma
Formation of Clotted blood. The clotting, blood seals the severed end of the blood vessels, and bones deprived of nutrients begin to die.
How many bones in the axial skeleton?
80 bones
What are the layers of a long bone?
Periosteum
Compact bone
Spongy bone
Medullary cavity
Endosteum
What are factors that affects bone repair?
AGE
Diet
Pre-existing bone disease
The type of bone
Some medications that affect how a bone heals
Pick up your skull and name the suture line. identify three.
Sagittal suture
Coronal suture
Lambdoid suture
What is bone generation?
With tiny capillaries developed within the hematoma
Phagocytes begin to remove the dead bone cells
A soft callus made of sponge bone material containing connective tissue and cartilage forms at the fracture site.
Using the skeleton in the classroom identify the axial skeleton
skull
Thoracic-rib cageVertebral column
Define red marrow and yellow marrow
Red bone marrow is found in the epiphysis and produces red blood cells, platelets, and white blood cells. Yellow marrow is located in the medullary cavity and primarily serves as a fat storage.
Define osteoporosis
Bones that lose mass, resulting in weak of bones that can deform and break more easily.
Go to your big skeleton in the class and identify the breakdown of the vertebral column.
Cervical c1-c7
Thoracic t1-t12
Lumbar l1-l5
Sacrum- 5 fusedCoccyx- 3-5 fused
Explain bone remodeling.
Osteoblast and osteoclasts continues to remodel over several months until the bony callus is replaced by normal bone.
Using the skeleton in the classroom and your whiteboard, identify the appendicular skeleton. Another student will spell the terms correctly on the whiteboard.

Draw the long bone on your whiteboard. Label and identify each part
Epiphysis - the end of the long
Metaphysis is a sight of bone growth during childhood and adolescent, thanks to the present of the growth plate
Diaphysis midsection of a long bone. It is made up of dense compact bone surrounding a medullary cavity that contains bone, marrow and blood vessels. The diaphysis is responsible for most of a long bones length.
Define sprain
A sprain is when a twisting action over- stretches or tears a ligament that connects bone at a joint
