05.1D Bone Growth, Development, & Remodeling (PART D)

Front

What is endochondrial ossification?

Back

A process of bone development where cartilage is replaced by bone, primarily occurring in long bones.

Front

What is intramembranous ossification?

Back

A process of bone development where bone forms directly from mesenchymal tissue, typically seen in flat bones like the skull.

Front

What hormone is released when blood calcium levels are high?

Back

Calcitonin.

Front

What is the role of calcitonin in the body?

Back

Calcitonin helps lower blood calcium levels by inhibiting osteoclast activity and promoting calcium deposition in bones.

Front

Which gland releases calcitonin?

Back

Thyroid gland.

Front

How does physical activity affect bone density in athletes?

Back

Physical activity increases bone density, making athletes' bones stronger and heavier due to the stress applied by muscles.

Front

What is the primary method of bone formation for most bones in the skeleton?

Back

Endochondral ossification.

Front

What is the function of osteoblasts?

Back

Osteoblasts are cells that synthesize new bone tissue.

Front

What is the function of osteoclasts?

Back

Osteoclasts are cells that break down bone tissue.

Front

What is bone remodeling?

Back

Bone remodeling is the process where old bone is replaced by new bone, involving the coordinated activity of osteoblasts and osteoclasts.
