RUSVM Microanatomy Section 1 Exam

Anatomy - Correct Ans-Science which deals with structures of the healthy body of animals and humans. The structure is revealed by naked eye observations and it is based on dissection Gross Anatomy - Correct Ans-Encompasses all those structures accessible by dissection and direct inspection Microanatomy-Histology - Correct Ans-Study of the tissues of the body and how cells and tissues integrate to form organs Embryology - Correct Ans-The science which deals with ontogenetic development I.e. with the development of a new individual What are the 3 branches of histology? - Correct Ans-Cytology General Histology, Histology Special Histology Cytology - Correct Ans-Science which deals with structure and function of the cell General Histology, Histology - Correct Ans-Deals with structure of tissues Special Histology - Correct Ans-Also called ORGANOLOGY deals with the microscopic structure of organs What are the 2 components that interact to make up tissues? - Correct Ans-Cells Extracellular Matrix (ECM) How does a light microscope work? - Correct Ans-Light beam is transmitted through a tissue What types of microscopy are included in light microscopy? - Correct Ans-Conventional bright field Fluorescence Phase-contrast Differential interference Confocal Polarizing What does a bright field microscope require? - Correct Ans-Requires staining, such as cytochemistry demonstration of mitochondria in sperms Phase contrast microscopy - Correct Ans--based on the principle that light changes its speed when passing through structures with different refractive indices -allows observation of LIVING non-stained structures Fluorescence microscopy - Correct Ans-Based on affinity of fluorescent compounds for specific cell components What are the advantages to LM? - Correct Ans--relatively inexpensive -provides rapid diagnosis -allows observation of living specimens -resolving power of LM is 0.2 um What are the disadvantages of LM? - Correct Ans--Image is 2D -resolving power is limited by the wavelength of light -requires maintenance -requires expertise for proper diagnosis (quality analysis
