    Terrific educational resource! As someone who is passionate about deepening my understanding of musculoskeletal anatomy, I appreciate this high quality video.

    Thank you for this. It's helped me isolate the exact malfunction, the source of pain. Thats the most important step in eliminating it. My specific injury has been hard to diagnose because the pain is so spread out and transfered. I believe the technical term, in original Latin, would be "royally jacked up neck". In all seriousness you've helped more than the other 50 videos. Thank you.
    If anyone is curious, or wants to assist, or discuss it, it would seem my problem is an instability in c1. Typically a tilt, where right side hangs low and left side is high, maybe up to a 1/4 inch difference, putting pressure on my left ear from below it. Rotating my head, mostly only to the left, 40-45 degrees causes some joint disfunction @ c2-c3, possibly also c3-c4 etc. Confirmed by jamming my thumb into the bottom of the right transverse process of c1, pushing it up gradually, and the majority of pain and dysfunction vanish for about 1-5 minutes. It quickly shifts back and increases pressure till the problem returns.
    My understanding is I shouldn't be able to shift c1 at all like that, but, with a little head moving till I find the angle it slips out, requiring significant pressure, I can tilt it, slide it left or right till it pushes on skull, raise it a little, or even rotate it horizontally till it pushes on either sides soft tissue. Is c1 being this loose as bad as it sounds? I've had a couple bad whiplash injuries and a pulling out of a headlock wrestling injury where something might have popped.
    Any advice would be appreciated. Is it possible some muscles were damaged and are now weak allowing the c1 shifting? Could exercise possibly help this? It seems like I can slightly keep c1 in the right place a little longer with a little flexing of some awkward weak neck muscles. Maybe. Help?

      i would personally be seeing your local chiropractor or osteopath and asking for an Cervical spine investigation.

    You can bend your neck near the top of your neck when nodding but keep most of your lower neck neutral. You can also bend at the base of your neck without nodding. These 2 movements seem mostly independent yet the only terms I hear are flexion/extension, and protraction/retraction. But there are other positions.
    What is the medical term for bending at the lower neck while keeping the head neutral and not nodding up or down?

      I'm not sure about the exact terms but I think it's ok to speak "flexion from", "extension from" - C3 to C7 for example. And flexion - extension from art. atlanto-occipitalis.

    Great video, confused on one thing from this video, to another video you have. In the other video you say the upper discs do not have a nucleus, in this one you’re saying they do?

      Intervertebral discs do indeed have a nucleus called the 'nucleus pulposus'. This is where a lot of water is located and plays a large role in shock absorption. Its surrounded by annulus fibrosus and a cartilaginous endplate. Hope I'm not too late in my response... only a year!

      I may have misspoke or I may have been unclear in my comment - the upper discs are smaller vs. the lower discs due to changes in the ratio between disc to disc height (e.g. cervical vs. thoracic vs. lumbar). All healthy, non-pathologic discs have a NP surrounded by perpendicular annular fibers. As we age, the disc will desiccate, thereby losing much of the watery/proteoglycan substance found within (along with other nutrients normally found within the NP). It is at this point that some resources will say the disc has lost its NP, though this is a much further advanced process associated with aging.
