When a skeletal muscle relaxes,myosin head attach to actin by breaking down ATP to ADP and phosphate with the help of myosin ATPase. The myosin head forms the cross -bridges on the active site of the actin.The cross-bridge pulls the actin which slide over the myosin. The release of ADP completes the cross-bridge movements . ATP attaches to myosin, and break the actin -myosin cross-bridge. Thus breaking of ATP into ADP and phosphate help the thin filament to return to their original position.
C cells of the thyroid gland secrete calcitonin.
<h3>
What does C cells of thyroid gland produce?</h3>
- The thyroid follicle, which is the gland's active component, is encircled by a single layer of epithelial cells, and the lumen is stuffed with colloidal material.
- It includes parafollicular cells, or C cells, which release calcitonin.
- The C-cells of the thyroid gland secrete calcitonin, a 32 amino acid hormone.
- When the concentration of blood calcium has grown over the usual range, the thyroid gland releases the hormone calcitonin, which lowers the level.
- The parafollicular cells, sometimes referred to as the C cells, of the thyroid gland are the principal producers of this polypeptide hormone, which has 32 amino acids.
