Parafollicular cells of thyroid and their function
Parafollicular cells, also known as C cells, are a type of cell found in the thyroid gland. These cells secrete a hormone known as calcitonin, which plays a crucial role in the regulation of blood calcium levels.
Function of calcitonin
- Calcitonin acts to reduce blood calcium levels by inhibiting the activity of osteoclasts, which are cells responsible for breaking down bone tissue and releasing calcium into the bloodstream.
- It also promotes the uptake of calcium by bones, thereby lowering the concentration of calcium in the blood.
Regulation of blood calcium levels
- When blood calcium levels are high, the parafollicular cells of the thyroid gland release calcitonin into the bloodstream.
- Calcitonin then acts on the bones to reduce the release of calcium into the blood, helping to bring the levels back to normal.
Conclusion
In summary, the hormone secreted by parafollicular cells of the thyroid gland plays a crucial role in reducing blood calcium levels. By inhibiting bone resorption and promoting calcium uptake by bones, calcitonin helps to maintain the balance of calcium in the bloodstream.
