Effect of hormones (e.g., PTH, vitamin D, estrogen) on the skeletal system:

🦴 Bone Health & Hormones – A Simple Guide

πŸ”Ή Why It Matters?
Bone health isn't just about calcium – hormones regulate bone growth, repair, and density. Imbalances from aging, diseases, and lifestyle factors can lead to osteoporosis and weak bones.

1⃣ Key Bone Hormones – "C3-STIGL" Mnemonic

πŸ’‘ Memory Trick: "C3-STIGL" sounds like 'Crystal,' like bone minerals!

Hormone

Function

Memory Trick

Calcitonin

⬇ Lowers blood calcium (prevents excess)

"Calci-tone it down!"

Calcitriol (Vitamin D)

⬆ Absorbs calcium for bones

"D for Deposit calcium"

Cortisol

🚫 Blocks bone growth (stress hormone)

"Cortisol Crushes bones!"

Sex Hormones (Estrogen, Testosterone)

🦴 Essential for bone remodeling

"Strong Skeleton Support"

Thyroid Hormones

πŸ— Needed for bone growth

"Thyroid Tunes bone formation"

Insulin

πŸ”„ Regulates bone growth & resorption

"Insulin Integrates bones"

Growth Hormone (IGF-1)

⬆ Stimulates bone formation

"Growth Gives strength"

Leptin

🧩 Influences bone metabolism

"Leptin Links fat & bone"
