Locate dermis on this anatomical reference. Read the original plate labels to confirm the view and adjacent structures.
Zoom in, then drag to inspect. Keyboard: + / − to zoom, arrows to pan, 0 to reset. Tap the numbered markers to explore parts.
Part A is a micrograph showing a cross section of thin skin. The topmost layer is a thin, translucent layer with irregular texture and areas where cells are sloughing off. The deepest layer is dark purple and extends into the third layer with finger like projections. The third light purple layer contains thin bands of fibers and small, dark cells. The fourth, and deepest layer, is darker than the third layer, but is still light purple. It contains thick fiber bands that are loosely packed. Part B is a magnified view of the epidermis of thick skin. It shows the topmost layer is five times thicker than the topmost layer of thin skin. The topmost layer of thick skin is also denser and less translucent than the topmost layer of thin skin.

Thin skin
Understand what you see.
Covers most body surfaces with regional variation in appendages and thickness.
Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.
How to recognise it.
- Relatively thin epidermis
- Hair follicles often present
- No distinct stratum lucidum
Point them out.
Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.
Think first. Then reveal.
Say your answer aloud before opening the suggested response.
01How do you identify thin skin?+
Relatively thin epidermis. Hair follicles often present. No distinct stratum lucidum.
02How do you distinguish it from thick skin?+
Thinner epidermis, no distinct lucidum and commonly hair/sebaceous units; examine multiple fields.
03What is the main connective tissue of reticular dermis?+
Dense irregular collagenous connective tissue.
04Which structures should you point out on this reference?+
Hair follicle; Sebaceous gland; Dermis. Covers most body surfaces with regional variation in appendages and thickness.
