<u>Microglia cells </u>are glial cells that respond to injury or disease by multiplying, and then engulfing cellular debris or even entire cells.
<h3>Functions of microglia</h3>
Microglia cells are the immune cells of the central nervous system and consequently play important roles in brain infections and inflammation. Recent in vivo imaging studies have revealed that in the resting healthy brain, microglia are highly dynamic, moving constantly to actively survey the brain parenchyma.
These active microglia can rapidly respond to pathological insults, becoming activated to induce a range of effects that may contribute to both pathogenesis, or to confer neuronal protection.
However, interactions between microglia and neurons are being recognized as important in shaping neural circuit activity under more normal, physiological conditions. During development and neurogenesis, microglia interactions with neurons help to shape the final patterns of neural circuits important for behaviour and with implications for diseases.

Answer:
The most important ethical problem faced by emergency physicians in end-of-life care is making ethical decisions on issues such as whether to perform resuscitation and continue life-sustaining treatment in cases where the patients are not competent to make decisions - a carer or family member has to on their behalf. Some argue that this is unethical, and can lead to being selfish; prolonging the patient's life for fear of losing them sooner, when it is against their wishes.
