The lumbar vertebrae are, in human anatomy, the five vertebrae between the rib cage and the pelvis .
Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.

Tetis of Fish T.S. under light microscope with white background
Leiden leaf c.s. under microscope
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
The coccyx is a triangular arrangement of bone that makes up the very bottom portion of the spine below the sacrum 3d illustration
Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
Microscopic close view of high vaginal swab Gram stain smear, 100x. diagnosis of Bacterial vaginosis (BV).
Mesenchymal dysplasia. Site: Placenta
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background

centropyxis aculeata (amoeboid organism) under the microscope - optical microscope x400 magnification

Freshwater aquatic zooplankton and algae under microscope view
Squash preparation of stained onion root tip cells showing late telophase and metaphase stages of mitosis. Bright field illumination on a Leica microscope, Image taken with the X100 objective lens.  Depth of focus is extremely shallow (less than one micron).  Optimum setting of the aperture for maximum resolution and good contrast. Chromatic aberation is inevitable in light microscopy, especially at this scale of magnification, but has been kept to a minimum in this image.
The upper pole of the left kidney lies at the level of the 12th thoracic vertebra, and the lower pole lies at the level of the third lumbar vertebra .
Photomicrograph of midge fly, Chironomidae family, eggs hatching. Eggs are encased in a gelatinous material that attracts debris. Live specimen. Larva about 0.5 mm long. Wet mount, 10X objective, transmitted brightfield illumination.
