Skeletal System - Bone Development and Growth

Bone formation in cartilage is called:

• Intramembranous Ossification

• Endochondral Ossification

• Proliferation Ossification

• Connective Tissue Ossification

Bone formation in connective tissue membranes is called:

• Intramembranous Ossification

• Endochondral Ossification

• Proliferation Ossification

• Connective Tissue Ossification

Large membrane covered spaces between developing skull bones that prevent premature closure of the skull.

• Ossification centers

• Epiphyseal plates

• Calcification zone

• Fontanels

In intramembranous ossification these are the locations where ossification begins, they are the oldest part of the bone.

• Primary ossification center

• Secondary ossification center

• Centers of ossification

• Hypertrophy centers

During endochondral ossification what is the first thing that has to be made?

• Primary ossification center

• Cartilage model

• Secondary ossification center

• Membrane model

The following are the steps of intramembranous ossification, which one DOES NOT belong?

• Mesenchymal cells in membrane make osteoblasts, starting bone formation

• Trabeculae gather and join together to form cancellous bone

• Blood vessels invade middle of cartilage model to produce primary ossification center

• Cells in cancellous bone form RBM, then form periosteum to make compact bone

The following are all involved in endochondral ossification, which one DOES NOT belong?

• Connective tissue membrane becomes progenitor cells to make osteoblasts

• Mesenchymal cells producing progenitor cells to make chondroblasts to make a cartilage model

• Producing a primary ossification center in the middle of bone model

• Producing a secondary ossification center in the ends of the bone

What causes long bones to increase in length?

• Addition of osteons on the outside of the compact bone

• Growth of the articular cartilage

• Growth at the epiphyseal plate

• Osteoblasts making bone in the membrane.

There are four zones at the epiphyseal plate, which one DOES NOT belong?

• Zone of resting cartilage

• Zone of calcification

• Zone of Hypertrophy

• Zone of ossification

• Zone of Proliferation

This zone at the epiphyseal plate has new cartilage being made through interstitial growth forming columns of condrocytes.

• Zone of Resting Cartilage

• Zone of Ossification

• Zone of Proliferation

• Zone of Hypertrophy
