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.

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 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.
What is it called when tissues are replace by harder minerals?
Ossification - tissue turns to bone Fossilisation - tissue turns to stone
The minerals found in bones are deposited by living cells called?
The bone cells that break down bone are called osteoclasts (bone+breaker). There are others called osteoblasts (bone+builder) which build bone. Usually there are about equal numbers of them in your body.They are always breaking and rebuilding in a process called bone remodeling. This is a life long process and your body will replace bones at a 10% rate per year.As you grow older, the osteoclasts out number the osteoblasts and the process of osteopenia (less dense bone) and osteoporosis ( weak bone) occurs.
When growth stops osteoclasts and osteoblasts cease their functioning?
No. You replace all of your bone tissue about every 8-9 years. It is constantly being remodeled.
Do osteoclasts and osteoblasts cease their functioning when growth stops?
No. You replace all of your bone tissue about every 8-9 years. It is constantly being remodeled.
How does the bone replace the cartilage in the body?
It uses cells called osteoblasts to lay down calcium and phosphorus in the extracelluar matrix that ultimately becomes bone, and turn into mature osteocytes.
What are bone forming cells?

This is a life long process and your body will replace bones at a 10% rate per year.As you grow older, the osteoclasts out number the osteoblasts and the process of osteopenia (less dense bone) and osteoporosis ( weak bone or bone+holes) occurs.
What is calcium buildup in muscle called?
Calcification in soft tissue, such as muscle, is called 'Calcinosis'. If it progresses into ossification (which involves the orderly deposition of calcium), it is called 'myositis ossificans'. However, the condition can occur in other connective tissue as well and may result from any kind of injury, including but not limited to inflammation. The term 'heterotropic ossification' has been proposed to replace it.
What type of bone cell breakes down bone and what event causes them to form more bones?
The bone cells that break down bone are called osteoclasts (bone+breaker). There are others called osteoblasts (bone+builder) which build bone.Usually there are about equal numbers of them in your body. They are always breaking and rebuilding in a process called bone remodeling.

What are types of tissue that make up the skeletal system?
the cells that make up bone are osteocytes_____Yes, osteocytes are the cells found within bone. Osteocytes are in fact osteoblasts that have been trapped in the bone matrix that they produce. In answer to the question at hand, "what cells make bones", the answer is osteoblasts.osteoblasts
Is bone constantly renewed through a process of remodeling that consists of resorption and formation?
a two-stage process (resorption and formation) that occurs throughout life. In the resorption stage, old bone is broken down and removed by cells called osteoclasts. In the formation stage, cells called osteoblasts build new bone to replace the old
