ANATOMIA Y FISIOLOGIA DEL TEJIDO UNIDAD I TEJIDOS CORPORALES ANATOMIA Y FISIOLOGIA DEL TEJIDO

ANATOMIA Y FISIOLOGIA DEL TEJIDO La histología humana tiene su origen en las tres capas del embrión (gástrula), a las que denominamos capas germinales porque de su crecimiento y diferenciación se forman todos los tejidos que integran a un ser completo y adulto.

ANATOMIA Y FISIOLOGIA DEL TEJIDO Los tejidos se diferencias por su estructura y su función, atendiendo además a la naturaleza y cantidad de la sustancia que se interpone entre las células especificas o sustancia intercelular

ANATOMIA Y FISIOLOGIA DEL TEJIDO La sustancia intercelular puede presentarse en mucha o poca cantidad y su estado físico varia del liquido y semiliquido al sólido.

Sickle cell

Sickle cell A computer-coloured scanning electron microscope image of a sickled red blood cell surrounded by normal cells. Sickle cell anaemia results from a genetic defect, and is particularly common in people of Afro-Caribbean origin. Affected red blood cells contain an abnormal type of haemoglobin, haemoglobin S, which crystallizes in regions of low oxygen concentration, such as the blood capillaries, causing a sickle-like distortion of the red blood cells. Sickled cells are fragile and easily disrupted, reducing the oxygen-carrying capacity of the blood and resulting in severe anaemia (actual size of sickle cell: about 19 thousandths of a millimetre from end to end).

Rod cells in retina

Rod cells in retina A colour-enhanced scanning electron micrograph of the retina in a guinea-pig eye. To the left of the picture is the photoreceptor layer which contains the light-sensitive rod cells that help convert light impulses into an image in the brain. To the right is the choroid layer of the retina which contains a network of blood vessels like the one shown emerging here.
