Carriage house- They are built to put carriages that horses are hooked up to and also to put stuff you use to ride horses with (called tack) in.

Horse tack- You use it to ride horses, such as a saddle, sturrips (the things you put your feet onto [like on a carosel] ), headgear (such as halters, bridles,
hacamores [which you'll be learning about later], reins, bits, harnesses, breastplates, martingales,  and accotrements).

 Hacamores- They are more gentle then a bridle with a bit.

Cartilage- It is a kind of body tissue in a horse's body.

Intervertebral discs- They are between vertebrae in our spines.
