Eye anatomy, SEM Featured SEM Print

Eye anatomy, SEM

Eye anatomy. Coloured scanning electron micrograph (SEM) of part of the ciliary body (red/yellow) of the eye, a ring-shaped structure inside the eye, surrounding the iris. This view looks at part of the ciliary body (arching from upper left to lower right), as seen from inside the eye. Part of the iris is seen at lower left. Part of the choroid (outer layer of the eye) is at top right. The ciliary body joins to ligaments that hold the lens in place behind the iris. The lens has been removed here. The ciliary body also contains the ciliary muscle that is contracted to alter the curvature of the lens and focus light on the retina at the back of the eye. These structures are at the front of the eye

Eyelash mite, SEM Featured SEM Print

Eyelash mite, SEM

Eyelash mite. Coloured scanning electron micrograph (SEM) of an eyelash, or follicle, mite (Demodex folliculorum), a harmless parasite which lives inside human hair follicles. This mite infests hair follicles (depressions in the skin which contain the roots of hairs) around the eyelids, nose and in the ear canals of humans. It feeds on oily secretions from the skin's sebaceous glands, which empty into the follicles, as well as dead skin cells. Infestation with follicle mites is usually symptomless; they cause no harm to their host. However, allergic reactions to the mites in susceptible individuals can cause hair loss and acne.

Eyelash mite tails, SEM Featured SEM Print

Eyelash mite tails, SEM

Eyelash mite tails. Coloured scanning electron micrograph (SEM) of the tails (pink) of three eyelash, or follicle, mites (Demodex folliculorum), protruding from a human hair follicle. The hair shaft (upper right) is also seen. These harmless parasites infest follicles (depressions in the skin which contain the roots of hairs) around the eyelids, nose and in the ear canals of humans. One follicle may contain up to 25 growing mites. They feed on oily secretions from the skin's sebaceous glands, as well as dead skin cells. Infestation is usually symptomless, but, in some individuals, allergic reactions to the mites can cause hair loss and acne. Magnification: x250 at 6x7cm size
