Solid substances (powders) may become corrosive or irritant when moistened or in contact with moist skin or mucous membranes. .

Meteorites delivered chemistry, and perhaps membranes, too.

Outer ear channels, nostrils, and mouth contain sand and green, mosslike, mucous threads.

That's your articular cartilage, and those are your synovial membranes.

For this fish, it's actually whole cells with nuclei and membranes.

These membranes are also quite similar, morphologically and functionally, to the membranes in your body, and we can use these, as they say, to form the body of our protocell.

And I present to you a concept that these are extended neurological membranes.

A company called Aquaporin is starting to make desalination membranes mimicking this technology.

It can be inhaled ( quot snorting quot ), but can also be injected or applied directly to a mucous membrane.

And in nature there are lots of examples of very efficient structures based on pressurized membranes.

Heart rates are slower you live longer diffusion of oxygen and resources across membranes is slower, etc.

But those bubbles have membranes very similar to the membrane of every cell of every living thing on Earth looks like, like this.

In part, amphibians are good indicators and more sensitive because they don't have protection from contaminants in the water no eggshells, no membranes and no placenta.

I've been a scanning electron microscopist for many years, I have thousands of electron micrographs, and when I'm staring at the mycelium, I realize that they are microfiltration membranes.

And all I wanted to show you is we can set up molecules in membranes, in real cells, and then it sets up a kind of molecular Darwinism, a molecular survival of the fittest.

For example, animal studies may provide useful information in terms of clinical signs of toxicity (dyspnoea, rhinitis etc) and histopathology (e.g. hyperemia, edema, minimal inflammation, thickened mucous layer) which are reversible and may be reflective of the characteristic clinical symptoms described above. Such animal studies can be used as part of weight of evidence evaluation

Because these anatomical features persist into early childhood, the dura may remain similarly vulnerable to bleeding beyond the newborn period. Indeed, both birth related bleeds and those attributed to shaking are most often located in the folds of membranes covering the brain that have more and larger blood vessels at this age than later in life.
