  2. Basal cell - Wikipedia

    en.wikipedia.org/wiki/Basal_cell

    Found in the lowest layer of the epidermis, the stratum basale, basal cells continuously divide in order to replenish the squamous cells that make up the skin's surface. [6] Every time a basal cell divides, it creates two daughter cells, one is an identical basal cell, and the other is a new somatic cell that undergoes terminal differentiation .

  3. Merkel cell - Wikipedia

    en.wikipedia.org/wiki/Merkel_cell

    Merkel cells are found in the skin and some parts of the mucosa of all vertebrates. In mammalian skin, they are clear cells found in the stratum basale [2] [3] (at the bottom of sweat duct ridges) of the epidermis approximately 10 μm in diameter. They are oval-shaped mechanoreceptors essential for light touch sensation and found in the skin of ...

    en.wikipedia.org/wiki/Malpighian_layer

    Histologic image of the epidermis with its layers named in white text.. The Malpighian layer (stratum mucosum or stratum malpighii) of the epidermis is generally defined as both the stratum basale (basal layer) and the thicker stratum spinosum (spinous layer/prickle cell layer) immediately above it as a single unit, [1] [2] although it is occasionally defined as the stratum basale specifically ...

  5. Stratum basale - Wikipedia

    en.wikipedia.org/wiki/Stratum_basale

    The stratum basale (basal layer, sometimes referred to as stratum germinativum) is the deepest layer of the five layers of the epidermis, the external covering of skin in mammals. The stratum basale is a single layer of columnar or cuboidal basal cells. The cells are attached to each other and to the overlying stratum spinosum cells by ...

  6. Keratinocyte - Wikipedia

    en.wikipedia.org/wiki/Keratinocyte

    A calcium gradient, with the lowest concentration in the stratum basale and increasing concentrations until the outer stratum granulosum, where it reaches its maximum. Calcium concentration in the stratum corneum is very high in part because those relatively dry cells are not able to dissolve the ions. [ 10 ]

  7. List of rail transport modelling scale standards - Wikipedia

    en.wikipedia.org/wiki/List_of_rail_transport...

    NMRA standard S-1.2 covers the popular model railway scales and S-1.3 defines scales with deep flanges for model railways with very sharp curves or other garden railway specific design features. In certain NMRA scales an alternative designation is sometimes used corresponding the length of one prototype foot in scale either in millimetres or in ...

    Normal histology of the breast, with basement membrane annotated near center-right. Prostate gland microanatomy, with basement membrane annotated at bottom.. As seen with the electron microscope, the basement membrane is composed of two layers, the basal lamina and the reticular lamina. [4]
