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 |
