During endochondral bone formation the primary center of ossification forms in the?
it develops in the diaphysis in long bones
What process determines bone shape?
Endochondral ossification
Ossification that involves replacing cartilage with bone is?
Endochondral ossification
Describe in proper order the events of endochondral ossification?
1. a bone collar is laid down around the diaphysis of the hyaline cartilage model. 2. cartilage in the center of the diaphysis calcifies and then develops cavities. 3. the periosteal bud invades the internal cavities and spongy bone forms. 4. the diaphysis elongates and a medullary cavity forms. 5. the epiphyses ossify.
How is the intramembranous bone differ from that of the endochondral bone?
Intramembranous ossification [flat bones] & endochondral ossification [long bones].The essential between them is the presence or absence of cartilaginous phase.Intramembranous ossification occurs when mesenchymal precursor cells proliferate & subsequently differentiate directly into osteoblasts w/c mineralize an immature bone tissue called woven bone,characterize by irregular bundles of randomly oriented collagen fibers & an abundance of partially calcified immature new bone called asteoid.At later stages this woven bone is progressively remodeled to mature,lamellar bone. Endochondral ossification entails the conversion of a cartilaginous template into bone.Mesenchymal cells condense & differentiate into chondrocytes w/c secrete the cartilaginous matrix.This embryonic cartilage is avascular,& during its early development,a ring of woven bone is formed by intramembranous ossification in the future mid shaft area.This calcified woven bone is then invaded by vascular tissue,& osteoclasts & osteoblasts are recruited to replace the cartilage scaffold w/ bone matrix & excavate the hematopoietic bone marrow cavity.

What are bones that develop from hyaline cartilage?
Endochondral bone

Endochondral ossification
Does Endochondral ossification occurs when chondrocytes replace osteoblasts in the matrix.?
No, you have it backwards. "Chondro" is the prefix for cartilage while "osteo" is the prefix for bone. Endochondral ossificiation is when the cartilage is replaced by bone, so you would have osteocytes moving into the matrix and replacing the chondrocytes.

What might happen if children's bones didn't have growth plates of cartilag?
They wouldn't grow or get bigger.

What develops into the back bone?
Neural tube.
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 formation of the endochondral bone?
masses of hyaline cartilage shaped like future bony structures;Grow rapidly for a time and then begin to change extensively.
Tough supportive tissue that is softer than bone?
A connective tissue that is more flexible than bone that but that functions within the skeletal system is called cartilage. Cartilage can be found at the tip of your nose, or in your outer ear.
