Head and neck movements (axial rotation)

In this video, we explore the intricacies of head and neck movements, with a particular focus on axial rotation and the median atlantoaxial joint. This joint, formed between the dens of the axis (C2) and the anterior arch of the atlas (C1), allows for smooth rotational movements of the head, such as looking over the shoulder.

By examining the C1 and C2 vertebrae in closer detail, you can see how the atlas and transverse ligament work together to form an osteoligamentous ring that surrounds the dens, creating a pivot-type joint that enables the rotational movements necessary for various activities.

Nice moving model. Well done! I think an additional one showing how 50% of extension is found at the atlantooccipital joint and the rest down the chain would be very educational for your audience.

Thanks! I’m here because I’m reading Stonehouse’s Anatomy for Artists and the explanation of this movement at the bone level was confusing me to no end. Now I get what he was talking about!! Awesome animation

This just helped me self-adjust a sticky spot. Thank you!

Axis (C2 vertebrae) has a pivot on which the atlas C1 rotates, carrying the skull above it.

Atlanto axial sublaxation in some diseases/disorders ex rheumatoid arthritis & Down's syndrome is very dangerous.

Hungaria - Végre most már jól látom, hogy hol szokott letapadni a nyak csigolyám és ha ki mozdítom, hogy recsen !
