Here's a more detailed breakdown:
* Shoulder blade (scapula): This is the flat bone that lies on the horse's back, just behind the neck. It's where the muscles that move the foreleg attach.
* Shoulder joint: This is the joint where the scapula connects to the humerus (upper arm bone). It allows the horse to raise and lower its foreleg.
* Point of shoulder: This is the most prominent point on the shoulder blade, and it's often used as a landmark for measuring the horse's height.
So, the shoulder on a horse is not just one specific point but rather a region that encompasses the scapula, shoulder joint, and surrounding muscles.
