Sample text

Light is then directed from a light source, through an aperture, then a substage condenser, and through the specimen. Light rays from the specimen pass through the objective lens and are focused for view through the eyepieces. This is accomplished mechanically by raising or lowering the position of the objective lens relative to the specimen. Resolution is the degree of separation that can be seen between adjacent points in a specimen—in other words, the degree of detail. The smaller the distance that can be distinguished between two points, the greater the detail in the image.

These cells are minimally active, so there is a correspondingly minimal complement of cellular organelles. epithelial cells, that is, various glands, intestines, and pancreas; the mammary gland makes a convenient and dramatic example. Mitochondria Called the powerhouses of the cell, mitochondria provide most of the ATP necessary for energyrequiring reactions. Two membranes enclose the gen­ erally elongated, thin, hot dog-shaped mitochondria. The outer membrane smoothly encapsulates the organelle, but the inner membrane is thrown into mul­ tiple folds that form partitions called cristae.

Cells without apparent mitotic figures or morphological changes were said to be in a resting or interphase period. It is now appreciated that these interphase cells carry out the normal functioning of tissues, for example, secretion of pancreatic enzymes or excretion activity of the kidney. The only “rest” at this time is from activities directly leading to cell division. As a general rule, once cells acquire their terminal functional activity, for example, many glan­ dular epithelial cells, they effectively cease dividing and are referred to G0 cells.
