What is intramembranous ossification? a. the formation of bone from preexisting hyaline cartilage models b. the formation of bon
e from preexisting elastic cartilage models c. the formation of bone from within fibrous membranes d. the formation of bone from preexisting fibrocartilage models
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
May not be right, but because of Oxygen and the growing of new skin? We rub our skin without noticing and it will become frail and rub off, creating new skin
The continued presence of vestigial structures suggests that these structures do not have a great impact on fitness, like in the whale, because even with these structures, the whale has been able to survive and reproduce.
