For some, payment ends with the death of the annuitant, but others provide for payment to a spouse or other beneficiary for years afterward. The fixed-period, or period-certain, annuity guarantees payments to the annuitant for a predetermined length of time.
Medulla Oblongota. 1  The part of the brain that regulates basic functions like heart rate, blood pressure, breathing, coughing, sneezing. 2  The part of the brain where the optic nerves cross., the point at which the optic nerves from the inside half of each eye cross over and then project to the opposite half of the brain.
The sneeze is accomplished by biochemical signals that regulate the beating of cilia (microscopic hairs) on the cells that line our nasal cavities. Cold and flu season may be winding down, but sneezing -- with allergies surely on the way -- is here to stay. We all do it, though some of us are more disruptively loud than others. It's a reflex we simply can't control.
