Cerebral Ischemia. Cerebral ischemia or brain ischemia, is a condition that occurs when there isnât enough blood flow to the brain to meet metabolic demand. This leads to limited oxygen supply or cerebral hypoxia and leads to the death of brain tissue, cerebral infarction, or ischemic stroke.erebral ischemia or brain ischemia, is a condition that occurs when there isnât enough blood flow to the brain to meet metabolic demand.
The slug is the unit of mass in the US common system of units, where the pound is the unit of force. The pound is therefore the unit of weight since weight is defined as the force of gravity on an object.hile the pound force and pound weight are the widely used units for commerce in the United States, their use is strongly discouraged in scientific work. The standard units for most of scientific work are the SI units. A newton can be seen to be the force required to accelerate 1 kg of mass at 1 m/s 2.
Slugs and snails are molluscs, like oysters and clams. They are both similar in structure, except that the snail is protected by a hard shell that makes it less vulnerable than slugs to dry conditions and the sun.Slugs and snails have a soft, unsegmented body that is 2 to 4 cm (.79 to 1.5 inches) long.The head has one or two pairs of tentacles. The front tentacles are sensitive to odours and sometimes taste, while each of the larger back tentacles have an eye at the end.lugs and snails are known as gastropods, which means stomach foot.. The foot located on the stomach is how they move around. Slugs and snails are also hermaphrodites, with both male and female organs.
