where is the mitochondria located in the human body
Mitochondrion Mitochondria (and related structures) are found in all eukaryotes (except one—the Oxymonad Monocercomonoides sp.).[2][62] Although commonly depicted as bean-like structures they form a highly dynamic network in the majority of cells where they constantly undergo fission and fusion. Mitochondria vary in number and location according to cell type. A single mitochondrion is often found in unicellular organisms. Conversely, numerous mitochondria are found in human liver cells, with about 1000–2000 mitochondria per cell, making up 1/5 of the cell volume.[13] The population of all the mitochondria of a given cell constitutes the chondriome. The mitochondrial content of otherwise similar cells can vary substantially in size and membrane potential,[63] with differences arising from sources including uneven partitioning at cell divisions, leading to extrinsic differences in ATP levels and downstream cellular processes.[64] The mitochondria can be found nestled between myofibrils of muscle or wrapped around the sperm flagellum.[13] Often, they form a complex 3D branching network inside the cell with the cytoskeleton. The association with the cytoskeleton determines mitochondrial shape, which can affect the function as well:[65] different structures of the mitochondrial network may afford the population a variety of physical, chemical, and signalling advantages or disadvantages.[66] Mitochondria in cells are always distributed along microtubules and the distribution of these organelles is also correlated with the endoplasmic reticulum.[67] Recent evidence suggests that vimentin, one of the components of the cytoskeleton, is also critical to the association with the cytoskeleton.[68]
Thalamus It is a midline symmetrical structure of two halves, within the vertebrate brain, situated between the cerebral cortex and the midbrain.
Liver The liver is a vital organ only found in vertebrates.[2][3] In humans, it is located in the upper right quadrant of the abdomen, below the diaphragm. The liver has a wide range of functions, including detoxification of various metabolites, protein synthesis, and the production of biochemicals necessary for digestion.[4] It also plays a role in metabolism, regulation of glycogen storage, decomposition of red blood cells and hormone production.[4]
