Intermediate filaments1 - unlike microfilaments and microtubules, they are verystable. Instead of being stacked proteins, as in actin, intermediate filaments are built of interlocking proteins. A dense2 sheet of intermediate filaments strengthens the nucleus3. Skin cells are filled with keratin, which at the last moment, just before they die. they cross link, to provide a really insoluble barrier layer of the skin. The cross linkage4 is between the sulphur atoms of cysteine, one of keratin's amino acids.
Interproximal wear - loss of enamel5 on the adjacent surfaces of teeth which is due to continual friction6 between the two surfaces as teeth move against each other.
Intratubular dentine - dentine formed inside the tubule by the odontoblast process in response to tooth wear, ageing or arrested caries.
Intrinsic fibres - refers to those fibres of cementum which were laid down by cementoblasts.
Ionised - the loss or gain of an electron from an atom which makes it no longer neutral but an electrically charged ion. If the electron leaves the atom it becomes a positively7 charged ion, such when calcium8 or sodium9 becomes ionised (Ca+, Na+). If the electron is gained, the atom becomes relatively10 negatively charged such as when chlorine or a phosphate group of atoms lose an electron (Cl-, PO4-). Ionized atoms or groups of atoms are more reactive than when they are neutral.
Ions - an atom or molecules11 which has a net electrical charge This may be caused by the temporary loss (positive ion) or gain (negative ion) of an electron. A calcium ion is written Ca+.
Ipsilateral - the same side as distinct from contralateral. Often used to refer to the teeth, joint12 or muscles on the same side as chewing is occurring.
