Calcium Regulation

Calcium Regulation

Regulation of serum calcium level
Answer:

Calcium level is regulated by

• Calcitriol
  • It is the active form of vitamin D

Serum calcium Mechanism:

Induces synthesis of calcium-binding protein
↓
This increases calcium absorption by the intestine
↓
This increases calcium level
↓
It also promotes calcification &remodeling of bone
↓
Parathyroid hormones
↓
Secreted by Parathyroid glands

Serum calcium Mechanism:

Binds to a membrane receptor protein
↓
Activates adenylate cyclase
↓
Liberates cAMP
↓
Increases intracellular calcium
↓
Action on bone

Stimulates pyrophosphatase& collagenase
↓
Causes decalcification of bone
↓
Results in bone resorption
↓
Action on the kidney
↓
Stimulates 1-Hydroxylation of 25-hydroxycholecalciferol
↓
Promotes production of Calcitriol
↓
Action on intestine
↓
Promotes synthesis of Calcitriol
↓
Increases calcium absorption

“Common challenges in mastering calcium regulation notes effectively: FAQs provided”

Calcitonin

• Secreted by parafollicular cells of the thyroid gland

Calcitonin Mechanism:

Increases osteoblastic activity
↓
Promotes calcification
↓
Decreases bone resorption
↓
Increases calcium excretion
↓
This decreases blood calcium level
