Do All Sweat Glands Open Directly onto the Skin?
Eccrine ducts open directly onto the skin surface. Apocrine glands in selected body regions usually drain into an associated hair follicle, giving a different outlet route rather than a channel inside the hair shaft.

What the illustration shows
English anatomy poster titled Two Sweat Glands. Two Exit Routes. Two skin cutaways compare eccrine and apocrine outlets. Left, a coiled tubular eccrine gland connects to a duct rising directly to a surface pore. Right, an apocrine coil connects to a duct that joins the upper canal of a hair follicle. Gold arrows trace the routes. An enlarged lower panel shows the apocrine duct opening into space beside the solid hair shaft, not inside it. Labels identify coils, ducts, pore, follicular outlet, follicle and shaft. Notes identify simplified regional examples, not to scale, and state that apocrine glands occur in selected regions.

How to interpret this poster
- Regional examples with illustrative depths, calibers and skin textures, not a complete pilosebaceous unit.
- Flow arrows give direction, not measured speed or identical secretion mechanisms.
- No universal apocrine distribution, human pheromone proof, antiperspirant or medication advice.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
