Exam 2 Flashcards
Is caused by injury to the flexor tendon and to the tendon sheath, it is usually in the front legs. Scar tissue in tendons causes a thickening and a bowed appearance. This is unsoundness
Bowed Tendon
Is arthritis in the bones of the hock. There may be swelling on the lower inside of the hock. This is a serious unsoundness.
Bone Spavin
Are pinched, narrow heels and a shrunken frog due to the lack of normal hoof expansion. This can lead to unsoundness.
Contracted heels
Is a hoof crippled by laminitis. The hoof has irregular growth rings and may have a dropped sole. The wall may separate from the sole at the white line. Often the feet are tender or the horse is lame. This is an unsoundness.
Foundered foot
Is a deep infection of the withers?
Fistula
Is an infection beneath the white line?
Gravel
Are small cuts or callouses on the inside of the ankles which indicate where the opposite foot strikes the ankle during movement?
Interference marks
A crippling change in the navicular bone within the hoof?
Navicular disease
A split in the side of the foot extending upward from the ground?
Quarter crack
Is a form of arthritis in the bones of the pastern?
Ringbone
Refers to a condition in which the stifle joint accidentally locks due to a loose ligament and poor conformation?
Stifled
A swelling on the front of the knee caused by an injury and is common in jumpers?
Big Knee
A swelling of the joint capsule of the hock due to a direct blow to the neck?
Bog Spavin
A permanent swelling on the point of the hock due to a direct blow to the hock?
Capped hock
A permanent swelling on the point of the elbow caused by pressure of the shoe when lying down?
Capped elbow
Are firm, fluid swellings on or near the ankles due to the joint capsule being stretched with extra joint fluid?
Windpuffs
A thickening of the ligament which runs along the back of the hock?
Curb
A condition in which the collateral cartilage of the hoof turns to bone?
Sidebone
A calcified lump that cements the splint bone to the cannon bone?
Splint
Considerations for proper hoof health:
- Daily care (picking, hoof treatments)
- Farrier care
- Conformation
- Environment
- Nutrition
- Exercise
Is a unique covering of the hoof that grows continually to compensate for wear and tear?
Outer shell
Provides shape of the foot and rigidity needed to bear weight?
Coffin or pedal bone
Expands and contracts to absorb shock and pumps blood from the foot back toward the heart?
Plantar cushion
Serves as a fulcrum and bearing surface for the deep flexor tendon, which is responsible for extension of the foot?
Navicular bone
Attaches the hoof wall to the coffin bone and is a main area of blood circulation within the foot?
Laminae
Gives protection to the sensitive inner structures and helps support weight. Attaches securely to the lower surface of the pedal (coffin) bone.
Sole
