Leavening agent. A leaven /ËlÉvÉn/, often called a leavening agent /ËlÉvÉnÉªÅ/ (and also known as a raising agent), is any one of a number of substances used in doughs and batters that cause a foaming action (gas bubbles) that lightens and softens.

Symptoms of Dislocated Rib. Depending on which rib has been dislocated, the discomfort or pain may be felt in your back or chest. After some time, the skin over the dislocated ribs may swell and bruise. The moment the injury happens, a popping sound can be heard and a lump may surface over the rib.
Rib fracture - aftercare. A rib fracture is a crack or break in one or more of your rib bones. Your ribs are the round, flat bones in your chest that wrap around your upper body. They connect your breastbone to your spine. A rib fracture can be very painful because your ribs move when you breathe, cough, and move your upper body. The ribs in the middle of the chest are the ones that break most often. Rib fractures often occur with other chest and organ injuries. So your doctor will also check to see if you have any other injuries.
