Follicular cells are found in the thyroid gland and produce and secrete thyroid hormones, namely T3 (triiodothyronine) and T4 (thyroxine). These hormones play a crucial role in regulating metabolism, growth, and development in the body.
Parafollicular cells, also known as C-cells, are also found in the thyroid gland, but they have a different function. These cells produce and secrete the hormone calcitonin, which helps in regulating calcium levels in the body. Calcitonin works by decreasing the amount of calcium released from bones into the bloodstream, thus lowering blood calcium levels.
Overall, both the follicular and parafollicular cells in the endocrine system are important for maintaining homeostasis and proper functioning of the body.
