(i) Microscopes are able to use either light or electrons as their illumination source, which are respectively known as light powered and electron microscopes.

(ii) Monocular microscopes have a single eye piece where as binocular microscopes posses two eye pieces, position side by side for simultaneous viewing with both eyes.

(iii) A simple microscope consists of one single lens system where as a compound microscope consists of two main lens systems, an ocular and objective, which are superimposed over each other to provide greater magnification.

In Biology, microscopes can also be described according to some specific purpose such as dissecting microscopes, which are commonly referred, as dissectors are especially suitable for use while dissecting very small or delicate specimens.

Microscopes are usually equipped with a series of interchangeable eyepiece lenses (oculars), each with different individual magnifications. Majority of

Capsule - The fibromuscular connective tissue capsule of the testes is known as the tunica albuginea, whose inner vascular layer is the tunica vasculosa. The capsule is thickened at the mediastinum testis from which septa emanate subdividing the testis into approximately 250 incomplete lobuli testis, with each containing one to four seminiferous tubules embedded in a connective tissue stroma.
