Human Skin-Sweat Gland Collage 40x

This sample slide clearly is a slice of skin and what lies below. On the left of the composite image, layers of the top of the epidermis can be seen. To the right, the sweat gland is evident. The cross section shows the several "vessels" of the gland and the tubes which carry its product.

Layers

These are the layers starting from the left and working toward the right.

The dark left most layer becomes a gradient to a lighter grey. Both dark and light have a texture that shows texture large and small.

Next, that lighter grey layer continues. The dark flecks in the grain become more pronounced.

The flesh darkens and experiences some rifts. I assume that the rifts are of the sample and not of the skin or gland.

The next "layer" has dark spots and a distinct wavy edge separating the dark and light parts. In this wavy area, the cells are more obvious and more numerous than previous layers.

Human Skin-Sweat Gland Layers E 400x

Here is the last of the epidermis and the start of the sweat gland. The nature of the tissue changes to be many small "glandules" intereconnected by stripy pink and white pathways. Some cell nuclei are still visible here.

Here is more "fibrous" tissue but still interspersed in the white and pink of the gland. The darks are darker than in the previous layer, but there seems to be a more pronounced structural component than on the previous image. It is like sinues or piping connecting the glandules of the sweat gland.

The final layer is a smooth white flesh veined with purplish/red in what almost looks like cross sections of interconnected bubbles.

Circular Shape

Somewhere in the sinuey second to last layer, there is a large red and white spot that appears to be the cross section of some sort of pipe. Because i think that the sweat gland would conduct all its product upward to the surface of the skin and this "pipe" is in cross section, I think it more likely that this is a vein or artery. The the photos may not do it justice, the actual color of this is intensely purple.

Cross section of vein/artery. There seems to be some fatty muscular tissue surrounding it on the top.

At 200x, the hole is seen to have six or seven layers of circumferential cells surrounding the opening. The cells are clearly not radial but circumferential.

Cells Concentrated Area

This area filled with many cells is located between the Layer F and the Layer G. Its dark edge looks similar to the one that shown in the Circular Shape.

At 100x, any details of inside of the area is not visible. Next to it  is another circular area with its central hole empty.

When zoomed on it, a circular pattern is visible. At the middle of the holes are barely visible cells without any orders. This area is speculated to be a kind of cross-section of vein filled with bloods.

Circular Area

In the lower right of the composite image at top, there is "glandule" that seems somewhat disconnected from the flesh of the rest of the sample. Nonetheless, it is connected by the sinuous piping of the gland. This glandule is spherical, light in color, and contains a darker center.

At 40x, the individual cells in the dark core are clearly visible as well as the cells ad pathways in the lighter area surrounding.

At 100x, the ligher area appears as cross sections white flesh with thin dark blubbly structures and pathways. Those bubbles are apparently indivudal cells as the nuclei are clearly visible. The core is denser and darker. Those dark cells seem to have a light coating beyond what you would expect from an animal cell but much less structure or hard than in a plant cell.

Nearly every one of the cells in the darker portions have a clear nucleus Structurally, it seems to be the cross section of a fibrous bundle.
