Document Summary

Functional histology histo=tissue logy=body of knowledge essentially the study of tissues. Cell or tissue function can be deduced by examining it"s component parts. The angle of the cut determines the shape you see. Can visualize specific molecules many at a time. Electron microscopy up to 100,000 volts short wavelength high magnification. Cells are the building blocks, smallest autonomous living unit. Barrier requires transport to move molecules, energy sources, or signals. By altering proteins associated with membranes compartment function becomes specialized. Organelles are the building blocks (elements) upon which cellular function is based. Rna - protein - nucleus - bind rna back to cytoplasm. Proteins from rough er move to golgi, to cytoplasmic vesicles. Number and type of organelles directly related to function. Epidermis dead cells at surface mucous secreting cells. Small intestine folding increases surface area,microvilli increases surface area = more absorption secretion. Pancreatic gland: cells specialized to make and secrete zygomen. Iga moved across cell to lumen of duct.
