Glossaryblock - to stop a strike, usually with an arm (leg blocks also exist). Not the same thing as parry. hammerlock - armlock in which uke's arm is held behind his back, and pushed as far up the back as torie can get it, thereby applying tortional stress on the shoulder joint. Aiki-style hammerlocks, more common as a tori move in the Zen Budokai charts, are held at the bottom of the back (coccyx) in order to place the uke in an off-balance position to control him more effectively. See police hammerlock. godan - fifth degree black belt. gokyu - Student rank 5. AKA "yellow belt". hachidan - eighth degree black belt. hanshi - system head. hiji - Elbow strike. ikkyu - Student rank 1 (next is black belt). AKA "first brown". judan - tenth degree black belt. kudan - ninth degree black belt. kuzushi - literally, "balance". In practice, "getting uke's kuzushi" means to take him off balance in some fashion, usually by continuing a motion uke has already begun. military step - in the right-handed version, the left foot is left as a pivot, and the right foot steps to the rear, so that the right foot is behind and at right angles to the left foot. Then the left foot pivots, turning the body 90 degrees. Often used with comealongs. nidan - second degree black belt. nikkyu - Student rank 2 AKA "second brown". parry - to redirect a strike, usually with the hand, such that it doesn't land. Leg parries also exist, but are less common.

The solar plexus is the nerve bundle affected when one "has the wind knocked out of them". To affect the solar plexus, strike just below the bottom of the breastbone. xiphoid process - small tab of cartilage that terminates the breastbone on the bottom part of the rib cage. This hangs down and is supported only on the top. If struck with sufficient force, it breaks off and may puncture the lungs, liver, spleen, or heart (use with care). sutemi - dynamic breakfall. Pronounced "stemi". tori - The person who applies a technique. In Zen Budokai charts, technques are initiated by the uke. This sometimes generates some confusion - it is easy to reverse these accidentally. uke - The person upon whom a technique is applied. In Zen Budokai charts, techniques are usually initiated by the uke. See tori. radius - One of the two bones in your forearm (the other is the ulna). The radius is the one that runs on the top of your forearm and ends in a bump just above your thumb. ulna - One of the two bones in your forearm (the other is the radius).
