🫁 Ya know that feeling when you can't take a deep breath? Sucks, right?
That's what your horse can feel like when their diaphragm is restricted. It's one of the most important muscles in the equine body! Here's a few more reasons why 👇🏾
🐎 Important structures that pass through the diaphragm:
🔸 Vagus nerve (innervates many organs)
🔸 Phrenic nerve (motor/sensory nerve for the diaphragm)
🔸 Vena cava (returns blood to the heart)
🔸 Aorta (moves blood to the organs)
🔸 Esophagus (moved food/water)
🔸Thoracic outlet (moves lymph)
🐎 Not to mention the fact that the liver is “suspended” from the diaphragm and the movement of the diaphragm aids in digestion and breathing.
🐎 A restricted diaphragm can be like someone repeatedly jamming the on button for the fight/flight response. Cue anxiousness and overreactivity. Which checks out because I'd probably panic a little too if it felt like I couldn't breathe properly. 😳
