Question

What is intramembranous ossification? a. the formation of bone from preexisting hyaline cartilage models b. the formation of bone from preexisting elastic cartilage models c. the formation of bone from within fibrous membranes d. the formation of bone from preexisting fibrocartilage models

Answer 1

Answer:

c. the formation of bone from within fibrous membranes

Explanation:

On the basis of formation ossification process is divided into two types:

1) Endochondral ossification : The process by which bone is formed from haline cartilage.

2) Intramembranous ossification : The process by which bone is formed by replacing a fibrous membrane and not from cartilage. This type of ossification occurs as follows :

• An ossification center appears in the fibrous connective tissue membrane.
• Bone matrix is secreted within fibrous membrane
• Woven bone and periosteum forms.
• Bone collar of compact bone forms and red marrow appears.

Hence option c. the formation of bone from within fibrous membranes is the right option
