Theme: Microscopy, Compound Light Microscope
1. In order, list the lenses in the light path between a specimen viewed with the compound light microscope and its image on the retina of the eye.
2. What happens to contrast and resolving power when the aperture of the condenser (that is, the size of the hole through which light passes before it reaches the specimen) of a compound light microscope is decreased?
3. What happens to the field of view in a compound light microscope when the total magnification is increased?

Microscopy and its characteristics

Explanation:

There are many lenses in the light path between a specimen viewed with the compound light microscope are following: specimen,objective lens,scope, ocular,eye and etc.when the aperature is decreased in compound  light microscope then the contrast will increase and the resolving power is decreased. This is due to the aperature related to the contrast by indirectly proportion relationship.the field of view is decreased in a compund light microscope this is because it will cover much smaller area in a higher level of details as details become better to show the object.

the glands which are associated with each description is given below:

pancreas - is an endocrine and exocrine gland that secretes juices with enzymes for digestion. salivary glands- with protection and digestion in the mouth. liver- secretes bile for digestion.   lachrymal glands - secrete tears to moisten eyes and protect them from particles and infection.   sweat gland -regulates water, salt, and temperature. oil glands - to form a protective barrier on the skin.   goblet cells - secrete mucus for protection.
