And if you're a girl, the mammary glands in your breasts could someday make breast milk to feed a baby. Other glands release hormones (say: HOR-mones), which are substances inside your body that tell it how to work and how to grow.

The 2004 World Health Organization classification of endocrine tumors defines pheochromocytoma as a tumor arising from catecholamine-producing chromaffin cells in the adrenal medulla â an intra-adrenal paraganglioma. Closely related tumors of extra-adrenal paraganglia are classified as extra-adrenal paragangliomas.
In all cells of all domains of life (archaea, bacteria, eukaryotes) a cytoskeleton is found (notably in all eukaryotic cells, which include human, animal, fungal and plant cells).The cytoskeletal systems of different organisms are composed of similar proteins.ubulin-like proteins are tubulin in eukaryotes and FtsZ, TubZ, RepX in prokaryotes. Actin-like proteins are actin in eukaryotes and MreB, FtsA in prokaryotes. An example of a WACA-proteins, which are mostly found in prokaryotes, is MinD.
