amazing inhabitants of the microworld under a microscope
Photomicrograph of algae, Cosmarium turpinii, a desmid. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
brown fat cell also called brown adipose tissue side to side with white fat cell 3d rendering
Bone marrow plasma cells .Plasma cell neoplasms are diseases in which the body makes too many plasma cells. Plasma cell neoplasms can be benign or malignant. Diagnosed with Immunostain CD138 positive.
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
Computational tomography image of the abdominal and pelvic regions.
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.

Backgrounds of Characteristics Tissue Tongue, Small intestine of Cat and Tissue of Esophagus rabbit under microscope.
Photomicrograph of two rotifers. Rapidly rotating cilia at top of heads, internal organs visible. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
Freshwater aquatic zooplankton and algae under microscope view
anaplastic thyroid carcinoma with heterologous differentiation (leiomyosarcoma)
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens.  Depth of focus is extremely shallow (just a few microns).  Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Host cells with spores (mold) are inside wood under the microscope for education.
flower bud of lilium brownii var. viridulum T.S. on microscopy
Amphora sp. algae under microscopic view, Diatoms, phytoplankton, fossils, silica, golden yellow algae
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.
Threadworm (Enterobius vermicularis) eggs containing worm larvae, computer illustration. Threadworms are nematode worms that parasitize the large intestine and caecum of many animals. In humans they cause the common infection enterobiasis. Nematodes are unsegmented worms that may be parasitic or free-living depending upon the species.
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.
Breast MRI or magnetic resonance imaging of Breast both side with breast silicone implant in women for screening breast cancer.
Early stage, two days, fertilized human eggs before transfer to the woman in an IVF procedure.
Plant tissue Structure, section (tissue) of stem plant tissue under a light microscope.
