Chapter 7 Skeletal System Part 2 Notes Flashcards
What are Intramembranous bones?
Flat and the skull
What are Endochondral Bones?
All other bones
What is Ossification?
When bones first form as hyaline cartilage than the cartilage gradually changes into bone tissues
What are the two forms of ossification?
Primary Ossification (Shaft) Secondary Ossification (Ends)
Which two regions are not converted into bone when a infant is born?
The Articular cartilage that covers the bone ends
The Epiphyseal plates (provide how much growth of the longs bones)
Where is the Epiphyseal disk located?
The band of cartilage between the epiphysis and diaphysis
What is resorption?
When osteoclasts dissolve bone tissue to release minerals
What is Appositional Growth?
The process by which bones increase in diameter
What controls the growth of long bones?
controlled by hormones (growth and sex)
Ends when the epiphyseal players are converted into bone itself
What is bone remodeling?
When bones retain normal proportions and strength during long-bone growth as the body increases in size and weight
What is Rickets?
A disease of children in which the bones fail to calcify (harden)
What is a fracture?
A break of the bone
What are the two types of fractures?
Closed (simple)
Open (compound)
What is a closed (simple) fracture?
a fracture in which the bone breaks cleanly and does not penetrate the skin
What is a open (compound) fracture?
A fracture in which the bone ends penetrate through the skin
