En microscopía óptica, la inmersión (generalmente en aceite, aunque también se puede efectuar en agua o con medios sólidos) es una técnica utilizada para aumentar el poder de resolución de un microscopio. Esto se consigue mediante la immersión en un aceite transparente de alto índice refractivo tanto de la lente del objetivo como del espécimen a observar, aumentando así la apertura numérica de la lente del objetivo.

Los aceites de inmersión son sustancias transparentes con las propiedades ópticas y las características de viscosidad necesarias para su uso en microscopía. Los aceites típicos utilizados suelen tener un índice de refracción de alrededor de 1,515.1​ Un objetivo de inmersión es una lente especialmente diseñada para ser utilizada de este modo. Muchas lentes condensadoras también proporcionan una resolución óptima cuándo están inmersas en aceite.

El primero en desarrollar está técnica a mediados del siglo XIX fue el óptico italiano Giovanni Battista Amici (1786-1863).

Contrast fast fibers with slow fibers in terms of diameter, glycogen reserves, myoglobin content, and relative abundance of mito
GrogVix [38]

Answer:

The skeletal muscle fibres are of two types namely slow-twitch muscle fibres (type I muscle fibre) and fast-twitch muscle fibre (type II muscle fibre).

The slow fibres are slow contracting and help in developing endurance such as long distance running, maintaining posture etc whereas fast fibres are fast contracting and help in movements which require force such as sprinting etc.

Other differences are summarized in a tabular form attached below.
