Human A and P Bone Anatomy and Homeostasis Flashcard

Front

What type of bone development occurs in endochondral ossification?

Back

Endochondral ossification is the process where bone develops by replacing hyaline cartilage.

Front

What is the primary function of osteoblasts?

Back

Osteoblasts are bone-forming cells responsible for synthesizing and mineralizing bone during the process of bone formation.

Front

What happens to the growth plates in bones as a person reaches adulthood?

Back

The growth plates, or epiphyseal plates, close, which stops further growth in height.

Front

Describe the role of osteoclasts in bone remodeling.

Back

Osteoclasts are cells that break down bone tissue, allowing for the resorption of bone and the release of minerals back into the bloodstream.

Front

What is intramembranous ossification?

Back

Intramembranous ossification is the process of bone development directly from mesenchymal tissue without a cartilage model.

Front

What are the stages of intramembranous ossification?

Back

The stages include the development of ossification centers, calcification, formation of trabecular bone, and the development of the periosteum.

Front

What is the difference between osteocytes and osteoblasts?

Back

Osteocytes are mature bone cells that maintain bone tissue, while osteoblasts are responsible for bone formation.

Front

What is the significance of the bone collar in endochondral ossification?

Back

The bone collar provides structural support and initiates the process of replacing cartilage with bone.

Front

What is the role of mesenchymal cells in bone formation?

Back

Mesenchymal cells differentiate into osteoblasts during bone formation, playing a crucial role in ossification.

Front

What is calcification in the context of bone development?

Back

Calcification is the process where calcium salts are deposited in the bone matrix, leading to hardening of the tissue.
