A beautifully insightful post from the amazing Camille. For any of my clients who have heard me say "Peripheral Self Defence System" - check out what this system is responsible for and how it affects their body
❤️🐴❤️
The horse has what we called a ‘Peripheral Self Defence System’.
This means it is aware of its environment and where it is in relation to it (peripheral).
The self defence part relates to its innate nature in being a prey animal (flight state).
When this system is activated one of the systematic responses of it, is to shorter the nuchal ligament. Causing contraction of the neck into the withers and a shortening from the head to withers.
It is what we call the “act of attention”.
When the horse is happily grazing and then lifts its head above the withers to look at something, it is instigating this peripheral self defence system response.
If whatever has caught its attention is not something to be afraid of then it will return to grazing, extending the nuchal ligament again.
If it is something that has captured its attention and either spiked its curiosity or caused the alarm bells to ring more, you will see the horse lift its head further and shorten the nuchal ligament even more.
This in turn puts the alarm response into action, directly initiating the medulla oblongata response of the brain to increase the breathing rate, heart rate and start the adrenaline activation processes of the body.
It is literally a tilt and contraction of the head that initiates the alarm bells of self defence.
Equine ConTact CARE works directly with skeletal pressure on this system and helps the horse to restore a natural relaxed response to potential danger or threat.
