The cervical spine is made up of 7 vertebrae. The first 2, C1 and C2, are highly specialized and are given unique names: atlas and axis, respectively. C3-C7 are more classic vertebrae, having a body, pedicles, laminae, spinous processes, and facet joints. C1 and C2 form a unique set of articulations that provide a great degree of mobility forBall-and-stick model of the methane molecule, CH 4.Methane is part of a homologous series known as the alkanes, which contain single bonds only.. In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.: 620 Hydrocarbons are examples of group 14 hydrides.Hydrocarbons are generally colourless and hydrophobic; their odor is usually faint, and may be
Commercial Districts: C1 & C2. C1-6 through C1-9 and C2-6 through C2-8 districts are commercial districts that are predominantly residential in character. They are mapped along major thoroughfares in medium- and higher-density areas of the city, such as Second and Lexington Avenues on the Upper East Side or Columbus and Amsterdam Avenues on theC3 - consultation, command, and control [NATO] C3I - 4 possibilities; the most common is command, control, communications and intelligence; C3ISTAR - C3 plus ISTAR; C3ISREW - C2ISR plus communications plus electronic warfare (technology focus) C3MS - cyber command and control mission system; C3/SA - C3 plus situational awareness Para-cycling classification. Para-cycling classification is the process of classifying participants in para-cycling covering four functional disability types. The classification system includes classes for handcycles for people who have lower limb mobility issues. The sport is governed by the Union Cycliste Internationale (UCI).

The ISO Corrosivity Classification table defines six corrosivity categories (C1 - very low, C2 - low, C3 - medium, C4 - high, C5 - very high, CX - extreme) based on one-year corrosion mass loss or penetration of steel, zinc, copper, and aluminum coupons. It is important to note that CX generally covers the most extreme environments - usually
