In terms of anatomy, which part is considered the forelimb of a horse?

The forelimb of a horse primarily consists of the structures that are involved in its front legs, which include the carpus (also known as the knee in horses) and metacarpus (the region between the carpus and the fetlock). This area is crucial for movement and support, as it bears much of the horse's weight and facilitates locomotion.

The shoulder is part of the forelimb but does not directly fit under the category of carpus and metacarpus, while hindquarters refer to the back legs, which belong to the hindlimb of the horse. The hind leg and tail are also not part of the forelimb, as they refer to different anatomical structures entirely. Lastly, ears and neck are areas located at the front of the horse but are not involved in the forelimb. The correct answer highlights the specific components that make up the forelimb, illustrating a clear understanding of equine anatomy.
