Document Summary

Dynamic histology: is an extension where we not only identify the tissues, but we examine functions of the cells and molecules that make up that tissue. Systemic human anatomy: macroscopic level; eyes only. Dynamic histology: microscopic level; sections and scopes. Plane of section is something that is very important in this course. Sections can be in cross section, oblique section or in longitudinal section. Important measurements: 1 cm = 10 mm, 1 mm = 1000 micrometers, 1 micrometer = 1000 nm, 1 nm = 10 a. What does this mean: thickness of a section = 5 micrometers, diameter of a cell = 10 micrometers, diameter of a lysosome = 200 nm, thickness of a pm = 75 a (7. 5 nm) The left side of the picture is for light microscopy, while the right side is for em. Chemical fixation: there are two ways to fix the tissue: Immersion: anaesthetize the animal and take a section of tissue.
