What is C2 in anatomy?
The axis is the second cervical vertebra, commonly called C2. It is an atypical cervical vertebra with unique features and important relations that make it easily recognisable.

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 for the skull.
Why is C2 called the axis?
Axis: The axis is the second cervical vertebra (symbol: C2). It is called the "axis" because the uppermost cervical vertebra (called the atlas) rotates about the odontoid process of C2. The joint between the axis and atlas is a pivot type of joint. It allows the head turn.

What is the lowest C on the keyboard?
It’s a really simple way of numbering the notes by their specific octave. The lowest C on the keyboard (the third white note from the end) is called C1. From there, each C to the right increases by one, so next we have C2, then C3. Then comes middle C, or C4 (those two names are interchangeable).
What registers extend from C to B?
Each octave register extends from C up to B. The next C then starts the following octave register:
What notes have a zero after them?
Those notes simply get a zero after them. A0, B0, then C1 (because every C begins a new octave register), D1, etc.
How many C notes are there on a piano?
In our study of note names so far, we’ve noticed that there is more than one C note on a piano. In fact, there are a grand total of 8 of them on a full 88 key piano. So how in the world are we supposed to tell them apart?
Why is there a middle C on the keyboard?
Here’s the point of all this: we do need to at least be aware of which octave we’re in. And that’s why there’s such thing as middle C – to help us know where we are on the keyboard. Middle C is a reference point. For example, if we say “the D above middle C”, everyone knows exactly which D note we’re referring to; the one that is directly to the right of middle C.
What notes are labelled with a 1?
So for instance, all of the notes between C1 and C2 are labelled with a 1. So from left to right, it goes: C1, D1, E1, F1 , G1, A1, B1, then the next note up is C2. Then D2, E2, F2, G2, A2, B2, C3, D3, E3 etc. I could go on, but I think you get the idea. Each C starts a new octave register and gets a new number.
