Vitamin B 12 deficiency anemia is more common in individuals of northern European descent. The condition is caused by one of the following: Vitamin B 12 deficiency caused by a lack of intrinsic factor in gastric (stomach) secretions--intrinsic factor is necessary for absorption of vitamin B 12.This type of B 12 deficiency anemia is technically pernicious anemia.itamin B 12 deficiency anemia is more common in individuals of northern European descent.

The body takes a very active role in temperature regulation. The temperature of the body is regulated by neural feedback mechanisms which operate primarily through the hypothalmus. The hypothalmus contains not only the control mechanisms, but also the key temperature sensors.
Role of the hypothalamus in set point temperature regulation. This closed-loop system is analogous to the set-point concept in temperature regulation. This is the analogous role of the human operator in the human body. This person receives temperature measurements and compares with the set point.ole of the hypothalamus in set point temperature regulation.
