In response, cells grow listless and metabolism slows.
But a healthy thyroid manages our cells so effectively that it can keep us running smoothly without us even noticing it's there.
Our nerve cells benefit from movement, and our skin is elastic, meaning it molds to our motions.
The bacteria in your mouth feed off of mucus, food remnants, and dead tissue cells.
It also contains phagocytic cells that help clean up any bone or cartilage debris that ends up in the joint.
The good news is there are effective treatments for OCD, including medications, which increase serotonin in the brain by limiting its reabsorption by brain cells, behavioral therapy that gradually desensitizes patients to their anxieties, and in some cases, electroconvulsive therapy, or surgery, when OCD doesn't respond to other forms of treatment.
If we consistently put more energy into our bodies than we burn, the excess will gradually be stored as fat in our cells, and we'll gain weight.
Firstly, the sprouting hair we see is mostly made up of keratin, the protein leftover from dead cells that are forced upwards as new cells grow beneath them.
Stem cells also play a role in regulating the growth cycle, and so scientists are investigating whether they can manipulate the activity of these cells to encourage follicles to start producing hair again.
However, with chronic stress our bodies become flooded with these chemicals, resulting in a loss of brain cells and an inability to form new ones, which affects our ability to retain new information.
In most mammals, the placenta is confined behind a barrier of maternal cells.
In the short term, stress can be advantageous, but when activated too often or too long, your primitive fight or flight stress response not only changes your brain but also damages many of the other organs and cells throughout your body.
Meanwhile, stress hormones affect immune cells in a variety of ways.

They come from these cells.
These blue and red cells are called doublecortin-positive cells.
