The term "coronary cushion" refers to a thick layer of tissue that surrounds the hoof of a horse. The correct spelling of this term, as per the IPA phonetic transcription, is /kɔːrənəri ˈkʊʃən/. The first syllable is pronounced with an open 'o' sound, followed by a stressed second syllable with a short 'u' sound. The final syllable is pronounced with a standard 'sh' sound and a reduced 'n' sound. Properly spelling technical terms like "coronary cushion" is crucial for accurate communication in various fields, including veterinary medicine.
A coronary cushion refers to a soft, spongy layer of connective tissue found in the hoof of hoofed animals, particularly horses. It acts as a shock absorber and protector, cushioning the structures within the hoof from impacts and excessive pressure. Located between the coffin bone (the third phalanx bone) and the hoof wall, the coronary cushion plays a crucial role in maintaining the overall health and functionality of the hoof.
This specialized tissue consists of a network of blood vessels, nerves, and adipose tissue that provide essential support and nourishment to the hoof structures. It acts as a resilient buffer, absorbing the force of each step and preventing it from reaching sensitive tissues such as the bones and joints. The coronary cushion also helps regulate blood flow to the hoof, contributing to the oxygenation and nutrition of the underlying structures.
In addition, the coronary cushion directly influences the growth and quality of the hoof. It secretes a semi-fluid, waxy substance called the hoof’s periople, which helps protect the hoof from excessive moisture, drying, and infection. The cushion also produces horn cells that contribute to the constant growth of the hoof wall.
Overall, the coronary cushion is an integral component of the equine hoof, providing essential protection, shock absorption, and growth regulation. Its health and proper function are vital for maintaining soundness and performance in horses.

The term "coronary cushion" is a compound word formed by combining the words "coronary" and "cushion".
The word "coronary" is derived from the Latin word "corona", which means "crown" or "wreath". In medicine, "coronary" refers to anything related to the heart's arteries, especially the coronary arteries that encircle the heart like a crown, supplying it with oxygenated blood.
The word "cushion" comes from the Old French word "coisson", which means a "bolster" or "pillow". It is ultimately derived from the Latin word "coxa", which means "hip". In the context of biology and anatomy, a cushion refers to a soft structure that provides support, protection, or acts as a shock absorber.
