Hormonal Regulation of Bone Growth and Endochondral Ossification

These flashcards cover the hormones involved in bone growth and the process of endochondral ossification.

Growth hormone

A hormone that increases osteoblast activity.

Thyroid hormones

Hormones that partner with growth hormone to stimulate osteoblast activity.

Estrogen

A hormone that promotes osteoblast activity.

24,25 (OH)2 Vitamin D

A form of Vitamin D that helps absorb more ionized calcium.

Calcitonin

Hormone produced by C cells of the thyroid gland that increases osteoblast activity.

Cytokines

Signaling molecules that increase osteoclast activity, especially after injury.

Parathormone

Hormone produced by the parathyroid glands that stimulates osteoclast activity.

1,25 (OH)2 Vitamin D

Active form of Vitamin D that promotes osteoclast activity.

Endochondral Ossification

The process by which bone tissue is created from hyaline cartilage.

Hyaline cartilage

The template used during endochondral ossification.
