ANS 216 Exam 1
Equine Science
| Question | Answer |
|---|---|
| Unsoundness | Any deviation in structure or function that interferes with a horse’s intended use or performance |
| Blemishes | Abnormalities which do not affect the intended use of the horse |
| Serviceably Sound | Structural problems/deviations which may have only limited affect on the horse’s ability to perform |
| Arthritis | Joint inflammation-many types of reasons |
| Desmitis | Inflammation/injury of a LIGAMENT |
| Sprain | Injury to a LIGAMENT from overstretching |
| Strain | A pulled or torn MUSCLE |
| Synovitis | Inflammation of the synovial membrane around a joint-swells from fluid accumulation |
| Tendinitis | Inflammation of a tendon often from overuse |
| Windpuff | Swelling of the pastern joint, a fluid filled distension of the joint bursa or capsule-usually only a blemish |
| Heaves or Broken Wind | also called COPD, varies in severity, allergic to dust/molds common to stables, may see heave line (asthma) |
| Roaring | obstruction of the airway usually involving disfunction of the larynx, usually hear when cantering or galloping |
| Photosensitization | Sunburn sensitivity |
| Blindness | UVitis, moonblindness |
| Undershot jaw | monkey mouth, lower jaw is farther out than top jaw, causes problems grazing |
| Parrot Mouth | top jaw is farther out than lower jaw, causes problems grazing |
| Abscess | temporary unsoundness, an extremely localized infection, which is generally "walled off" within the hoof capsule |
| White line disease | white line becomes crumby and soft |
| Contracted Heels | a condition where the horse’s heel is narrower than normal usually cases the horse to grow very upright heels |
| Quittor | Infection on the coronet band |
| Laminitis | inflammation of the laminae under the hoof wall |
| Navicular Disease | inflammation of the bone which may affect the bone, bursa or tendon; afflicted horses will have heal pain and tend to point their toe at rest, usually occurs in the front feet only |
| Sidebone | ossification of the lateral cartilage surrounding the pastern |
| Ringbone | bony enlargement near coronet band that may involve pastern or coffin joint |
| Bowed tendon | thickened enlargement of tendon/ligament that are in the cannon region formed by ruptured tendon tissue, most frequently superficial flexor tendon, deep digital flexor tendon, or suspensory ligament |
| Contracted tendons | tendons are not able to stretch, in extreme cases horse will be up on tips of their hooves |
| Stringhalt | nerve disorder where horse unable to control nerves and will snatch feet up as walking, is not painful |
| Sweeney | depression in muscle due to prior concussion, is not painful |
| Stifled | an unsoundness that is caused by upward fixation of the patella, the horse will drag its toe |
| Capped hock | swelling at the point of the hock due to an injury of trauma causing increased synovial fluid production, usually caused by horse kicking something |
| Capped Elbow | Swelling at the point of the elbow caused by injury resulting in excess secretion of synovial fluid |
| Fistulous withers and poll evil | caused by bruising but may become infected, the bursa will swell then eventually rupture, usually caused by horse rearing and hitting something, or poor fitted saddle |
| Thoroughpin | a puffy condition in the hollow of the hock, mostly on the outside, rarely cases lameness, so is considered a blemish |
| Bucked shins | swelling due to tearing of the periosteum |
| Osselets | abnormal bony growth at the fetlock (ankle) |
| Sesamoiditis | caused by stress of the fetlock joint, low long pasterns are most prone to this disease |
| Ringbone | caused by a horse being base narrow or base wide |
| Bog Spavin | Soft swelling on the dorsomedial (front) side of the hock |
| Bone Spavin | osteoarthritis, a condition in horses caused by the deposition of new bone and sometimes producing lameness |
| Curb | Injury or strain causing enlargement of the hock tendon or ligament, located just below the hock on the lateral (side) of the upper cannon |
| Splint | Calcification between splint and cannon bones due to injury, stress, or poor confirmation |
