Which ossification method would form a femur?
The femur is formed through the endochondral ossification process. This is where bone replaces the cartilage. There are six steps in this type of ossification and they are as follows; one the development of cartilage model, two the growth of the cartilage model, three the development of the primary ossification center, four the development of the medullary cavity, five the development of the secondary ossification centers, and six the formation of articular cartilage and the epiphyseal plate.
Do growth plates lie between primary and secondary ossification centers?
yes they do
What is the primary ossification center of bone?
Secondary ossification centers appear in the epiphyses.
Where do you find primary and secondary ossification centers?
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.
What are the outward conical projections on some fetal cranial?
ossification centers
What occurs first in the embryonic development of most of the bones of the skeleton?
These are the steps in bone development which begins in the second month of development:â—¾Uses hyaline cartilage "bones" as models for bone constructionâ—¾Requires breakdown of hyaline cartilage prior to ossificationStages of Endochondral Ossificationâ—¾Formation of bone collarâ—¾Cavitation of the hyaline cartilageâ—¾Invasion of internal cavities by the periosteal bud, and spongy bone formationâ—¾Formation of the medullary cavity; appearance of secondary ossification centers in the epiphysesâ—¾Ossification of the epiphyses, with hyaline cartilage remaining only in the epiphyseal plates

What are the main events of endochondral ossification?
Meschyme (embryonic connective tissue) develops into a body of hyaline cartilage, covered with fibrous perichondrium, in the location of a future bone. For time, the perichondrium produces chondrocytes and the cartilage model growth in thickness.
When do primary centers of ossification first appear?
No, the primary ossification center of a long bone is found at the center of the diaphysis. Hope that helps.
What bone is found towards the ends of long bones?
Long bone: the ends are called the epiphysis, the shaft is called the diaphysis. There is articular cartilage on either ends. The long bones distally and proximally have red marrow. There is yellow marrow in the diaphysis. The yellow marrow is mostly fat. On the surface of the bone is a periosteum which covers the endosteum. The center is called the medullary cavity.The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone. It is connected to the bone shaft by the epiphyseal cartilage, or growth plate, which aids in the growth of bone length and is eventually replaced by bone.
What are the laws of ossification?
Ossification refers to the process of bone formation, where mesenchymal cells differentiate into osteoblasts that produce bone matrix. The laws of ossification include Wolff's Law, which states that bones adapt their shape and structure in response to mechanical stress, and Davis' Law, which states that soft tissues, including bone, remodel and adapt to the stresses placed upon them. These laws help explain how bones grow and adapt to their environment.
Most hyaline cartilage long bones show primary ossfication centers by?
12 weeks gestation
