Here you will find, for example, animal cells, DNA double helix, a giant DNA model, models showing cell division, both mitosis and meiosis, as well as chromosome models. These models make it easier to create an understanding of genetics that many consider is a difficult topic.
In this category we have collected products that belong to genetics and microscopy. You will find, for example, animal cells, DNA double helix, a giant DNA model, models that illustrate cell division, both mitosis and meiosis as well as chromosome models. These models make it easier to create an understanding of genetics that many consider to be a difficult subject.
This selection we call microscopic anatomy. The microscopic anatomy is about structures that are examined by optical microscopy or electron microscopy.
In the wide and wide range you will find, first and foremost, models that display tissues and cells. These include liver tissue, kidney tissue, bone tissue, a model of blood vessels, the tongue tissue as well as a model of specific tissues and cells of the eye.
You will also find models of individual cells as well as structures within the cell. These include a skeletal muscle muscle fiber, a general animal cell, an undifferentiated human cell, models of the phases of meiosis and mitosis, as well as DNA models.
In the past, we called the committee microanatomy. The models in the sample are used both for histological purposes (the doctrine of tissue), for biological purposes as well as for understanding diseases.
Anatomically, the models of tissues and cells show the structure / architecture characteristic of the body's tissues. With the model of liver tissue in hand you can see liver lobules, liver cells, bile ducts, central vein and the Glissonian triads (portal triads).
With the model of kidney tissue in hand you can see the beginning of the ureter (ureter), the renal cortex (renal cortex), the renal marrow (medulla renalis) in the form of pyramids and the entire renal pelvis (with calices). Furthermore, you can see many details regarding small and physiologically important structures such as the renal body (corpusculum renis), the nephron with Henles sling and tubulus, and collecting ducts.
The model of bone tissue shows the distinct differences between the compact bone (substantia compacta / cortical bone) and the spongy bone (substantia spongiosa / trabecular bone). With the model in hand, one can see that the former consists of bone matrix in the form of slats organized in Haversian systems (cortical osteons). One can also see the spongy bone tissue's spongy network of trabecules with communicating cavity filled by bone marrow. Obstacles such as the retina (periost) and end cheese are also shown.
The blood vessel model first shows 2 arteries and 1 vein. With the model in hand you can see details such as the venous pump (the flap and muscle pump system) and the different layers in the walls of the blood vessels (tunica intima, tunica media and tunica adventitia).
The model of the tongue shows the many different tissues. With the model in hand you can see details such as taste buds, nerve supply (via the skull nerves), tongue muscles and the 4 papillae (papillae vallatae, papillae filiformes, papillae fungiformes and papillae foliatae).
The model of specific tissues and cells of the eye shows the retina (retina), choroid (vein) and sclera (retina) as well as related nerve cell branches. With the model in hand, you can see the photoreceptors (rod and tap layer / stratum photosensorium) with many details.
As for the models that show individual cells as well as structures in the cell, you will find, for example, the model of a muscle fiber from the skeletal muscle. With the model in hand, one can see the neuromuscular end plate and details such as sarcolemma, Transverse Tubules / T-tubules, sarcomeres, myosin and actin filaments, cell nucleus and mitochondria.
The models of cells show primarily organelles. With one of the models in hand, apart from the cell membrane (plasma lemma), structures such as the nucleus (cell nucleus) with chromatin and nucleolus, ribosomes, rough and smooth ER, the Golgi apparatus, mitochondria, lysosomes and peroxisomes can be seen.
With a model in the hand of mitosis or meiosis one can see the different phases of cell division in an educational way.
DNA models offer various insights into the chemical structure of DNA strands that underlie the genome / genome / genes.
Clinically, the models of tissues and cells can be used to understand diseases of the respective tissues. It can be, for example, liver diseases such as cirrhosis ("cirrhosis of the liver), acute and chronic hepatitis as well as NASH and liver tumors. It can also be kidney diseases such as diabetic nephropathy and glomerulonephritis.
The model of bone tissue can be used to understand, among other things. osteoporosis and myeloma. The model of blood vessels is ideal for understanding atherosclerosis, blood clot, DVT and the use of supporting stocking, while the model of the tongue can be used to understand disorders such as fissured tongue, infections, cancer and issues related to the supply of the cranial vein to the tongue.
The model of tissues and cells of the eye can be used to understand disorders such as retinal detachment, AMD, uveitis, scleritis, as well as metastases and primary tumors.
The models of single cells as well as cell structures can also be used for clinical purposes. The model of a skeletal muscle muscle fiber can be used to understand hypertrophy as well as the importance of protein. The
