Abstract:
GROWTH HORMONE INSUFFICIENCY: Bone mass is reduced and bone remodeling diminished in case of growth hormone insufficiency. ACROMEGALY: In acromegaly, cortical bone mass increases due to excessive growth hormone. The effect on trabecular bone is less well established. ON THE CELLULAR LEVEL: Growth hormone stimulates the bone formation action of osteoblasts and their synthesis of insulin-like growth factor I. EFFECTS OF TREATMENT: Contradictory results have been obtained in adults treated with growth hormone for insufficiency. Generally, markers of bone remodeling are increased, but the effect on bone density is less clear. Long-term studies are needed. EFFICACY OF GROWTH HORMONE TREATMENT ON OSTEOPOROSIS: Growth hormone has been found to have an effect. Several randomized trials have demonstrated moderate increases in bone density.

Bone Remodeling
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
