Usually overuse by repetitive movements of the sinus tarsi from over pronation or an ankle sprain that is inverted are the two (2) reasons causing this area of pain. Both cause irritation and traumatic injury to the tissues that are located in the sinus tarsi.
Answer   Hydrogen is composed of one proton and one electron.   Some isotopes of hydrogen are slightly different. Deuterium contains one proton, one neutron, an â¦ d one electron. Tritium contains one proton, two neutrons, and one electron.
The proton is a subatomic particle, symbol p or p+ , with a positive electric charge of +1e elementary charge and mass slightly less than that of a neutron. Protons and neutrons, each with mass approximately one atomic mass unit, are collectively referred to as  nucleons . One or more protons are present in the nucleus of an atom. The number of protons in the nucleus is referred to as its atomic number. Since each element has a unique number of protons, each element has its own unique atomic number. The word proton is Greek for first, and this name was given to the hydrogen nucleus by Ernest Rutherford in 1920. In previous years Rutherford had discovered that the hydrogen nucleus (known to be the lightest nucleus) could be extracted from the nuclei of nitrogen by collision.
