Very interesting. Also look at the picture of the horse and human anatomy.

An anatomical structure far more clinically relevant than many realiseโผ๏ธ
๐ ๐ช๐ต๐ฎ๐ ๐ถ๐ ๐ถ๐?
Myo = muscle
Dural = dura mater (protective membrane around the spinal cord)
๐ The myodural bridge = a direct link between the re**us capitis posterior minor muscle and the dura mater.
๐ ๐๐ผ๐ฐ๐ฎ๐๐ฒ๐ฑ ๐ฏ๐ฒ๐๐๐ฒ๐ฒ๐ป:
Atlas (C1) & Axis (C2)
Atlas & Occiput
โ ๏ธ This region is one of the few places where the spinal cord is not fully protected by bone.
Also โ the greater occipital nerve runs through here โ vulnerable to irritation & strain.
โก ๐ช๐ต๐ ๐ถ๐ ๐ถ๐ ๐ถ๐บ๐ฝ๐ผ๐ฟ๐๐ฎ๐ป๐?
Because of its proximity to the brainstem, dysfunction here can affect:
Hearing ๐
Swallowing ๐ฎโ๐จ
Eye control ๐
Muscle tone ๐ช
Chronic irritation = hypersensitivity to sound/light, swallowing issues, abnormal muscle responses.
This explains why horses with poll trauma or pull-back injuries can show long-term behavioural and physical problems that seem disproportionate to the original event.

If your horse (especially a young one ๐ด):
Pulls back while tied โ
Shakes its head immediately after โ
๐ Call a qualified equine osteopath within 1โ2 weeks!
And never teach young horses to tie to something solid. ๐ซ

Halters & bridles lie directly over this region
A single pull-back = potential trauma to spinal cord + brainstem
Some dressage โtechniquesโ (like the nuchal ligament flip) can strain this area โ long-term dysfunction, pain & instability
๐ซ ๐๐ฒ๐ ๐๐ฎ๐ธ๐ฒ๐ฎ๐๐ฎ๐:
Disturbance of the CO junction & myodural bridge isnโt โjust muscular.โ
It creates a cycle of neurological stress, pain, and sensory overload.
๐ Prevention > cure.
Avoid hard tying & training aids that compromise this region.
โจ For horse health, behaviour, and performance โ protect the poll.
