What Is Smegma? Smegma is a thick, white, cheesy substance that collects around your genitals. It's normal to have some smegma. And it usually isn't a health problem, but bacteria can grow in it, causing it to smell bad. Keeping your penis orvaginaclean is the best solution. Who Gets...
Vascular smooth muscle cells (VSMCs) are the most abundant cell in vessels. Earlier experiments have found that VSMCs possess high plasticity. Vascular injury stimulates VSMCs to switch into a dedifferentiated type, also known as synthetic VSMCs, with a high migration and proliferation capacity ...
He waxes poetic in his writing, describing the bacterial colony on his pearly whites as "a little white matter, which is as thick as if 'twere batter" [source: Dobell]. After placing the sample under a compound microscope, van Leeuwenhoek saw the microbes were moving. It's aliiiive!
One of the reasons why fats are important for your skin, is because the fats that you eat are incorporated into the outside coating of a cell, the cell membrane. Since cell membranes protect cells from damage, such as free radical induced damaged, you want this protective layer to be as ...
Make an edible plant cell model. For the cell wall, bake a cake in a large pan and cut out the middle to leave a thick border. Spread frosting on the inside of the wall to represent the plasma membrane. You can recycle some of the cake by covering a chunk of it in black frosting...
Inside the fiber, stretching along the long axis between T-tubules, is a membrane system called the sarcoplasmic reticulum, which stores and releases the calcium ions that trigger muscle contraction. Contracting a Muscle During contraction, the thin filaments slide past the thick filaments, ...
Long bones: Long bones have a slightly curved shaft capped on both sides with hyaline cartilage and are longer than they are thick. They're made mostly of compact bone, allowing them to support great amounts of weight and withstand pressure. The femur is an excellent example of the strength...
What you can't see from this photo is how thick and chunky this calculator was and how big its batteries were. Modern calculators are far more advanced, much cheaper, and use a fraction as much battery power.Modern calculators have much in common with computers: they share much of the ...
Above: this site-built flat roof walking surface over a New York home used synethtic decking as both sleepers and runners to provide an access walkway across a flat roof up to the home's entry door. This is a modified bitumen membrane roof not intended to withstand regular foot traffic nor...
In BMMs, IpaB is internalized within 15 min to vesicular-like compartments (Figure 3a, upper row). In contrast, in HeLa cells, IpaB localized to the cell membrane 1 h after the treatment (Figure 3b) and was partially internalized after 4 h of incubation (Supplementary Figure 3a)....
