Answer:

Vainas sinoviales tendinosas

Explanation:

Las vaina tendinosas o vainas sinoviales son mangas de tejido de protección que se encuentran alrededor de las articulaciones o rodean a los tendones. Estas vainas permiten que los tendones se deslicen suavemente, produciendo un líquido (líquido sinovial) que mantiene al tendón lubricado. De este modo, las vainas tienen como función evitar el roce entre el tendón y el hueso. Las vaina tendinosas conforman un revestimiento de dos capas: una interna unida al tendón y una externa de tejido conectivo.

Which best blocks X-ray particles and can therefore be observed more closely through the use of this technology?
Vedmedyk [2.9K]

Answer:

The correct answer would be bones.

X-rays are high energy electromagnetic waves which have an ability to penetrate most of the biological tissues.

In the X-ray machine, a beam of high energy X-rays is passed through the filters and subject and then fall on the detector or photographic film to produce X-ray.

Dense tissues like bone, teeth, tumors et cetera blocks or stops most of the X-ray particles from reaching the detector or photographic film.

It forms glowing pictures on the X-ray film or photographic film.

The denser the material the brighter the image will be formed on the photographic film.
