The word "fetlock" is spelled as /ˈfɛtlɒk/. It refers to the joint between the cannon bone and the pastern in horses, corresponding to the human ankle. The first part of the word is pronounced as "fet", which is followed by "lock". The sound /ɒ/ in "lock" is pronounced as the "o" in "lot".

A fetlock refers to the joint or region of a horse's leg that is located just above its hoof. This anatomical feature is commonly found on the back legs of horses but can also be present on the front legs as well. The fetlock consists of the metacarpophalangeal or metatarsophalangeal joint, which is formed by the distal end of the cannon bone and the proximal end of the long pastern bone.
The fetlock is a crucial part of a horse's leg structure as it allows for flexibility and mobility during movement. It acts as a shock absorber, helping to minimize the impact on the leg joints when the horse is in motion. The integrity and strength of the fetlock greatly affect a horse's overall soundness and performance.
In addition to its functional significance, the fetlock is also a notable site for potential injuries in horses. Overextension, sprains, fractures, and ligament damage are some of the common issues that can affect this part of a horse's leg. Due to its vulnerability, horse owners and riders often pay close attention to the fetlock area, monitoring for any signs of heat, swelling, or lameness that may indicate an injury or inflammation.
Overall, the fetlock is an essential component of a horse's leg structure, aiding in its locomotion and overall soundness. Understanding and caring for this part of a horse's anatomy is crucial for maintaining the health and well-being of these magnificent animals.

The word "fetlock" originated from Old English, where it was known as "fotloc", combining "fot" (meaning "foot") and "loc" (meaning "lock" or "enclosure"). It referred to the joint or tuft of hair on the lower part of a horse's leg above the hoof. Over time, "fetlock" has retained its meaning and has become the commonly accepted term for that particular part of a horse's leg.
