diaphysis
it develops in the diaphysis in long bones
There are two ways bones are formed, intramembranous ossification, and endochondral ossification. Intramembranous ossification is how the flat bones are formed, while the long bones are formed with endochondral ossification.
ossification
Endochondral ossification is the type of ossification in bones that are formed in cartilage. This process involves the replacement of cartilage by bone during development and growth.
Primary centers of ossification first appear in the diaphysis of long bones during embryonic development, around the 8th week of gestation. This is where bone tissue begins to replace cartilage through endochondral ossification.
Long bones are developed by endochondral ossification, which requires a cartilage precursor.
No, INTRAMEMBRANOUS OSSIFICATION, is developed from a fibrous membrane. Essentially all bones below the base of the skull (except the clavicles) are formed from endochondral ossification. Endochondral ossification uses hyaline cartilage "bones" as a pattern for forming true bones.
Intramembranous ossification
Endochondral ossification.
The primary ossification center is located in endochondral bones (the bones that form as a fetus is growing in the womb). It is in the shaft part of the bone (diaphysis), or the long, skinny part of it. Growth takes place in the epiphysial center of ossification. This primary ossification center is the key location for bone formation.
No
Most bones in the appendicular skeleton develop from cartilage in a process known as endochondral ossification.
