history Flashcards
study of organs
organology
study of tissues
histology
study of cells
cytology
greek word of tissue
histos
it is a greek word mean study of knowledge
logia
Study of cells, tissues, and organs, it embraces is a function as well as of structure
histology
It binds the various body parts
Connective tissue
He believed that the living organisms could develop from nonliving materials
aristotle
He believed that the living organisms could develop from nonliving materials
aristotle
they mounted two lenses in a tube to produce the first compound microscope
Hans and Zacharias janssen
They are spectacle makers and dutch lens grinders
Hans and Zacharias janssen
He observed the cells from the cork
Robert Hooke
Robert hooke said that cells are what shape appearance
Box shape appearance
He’s the first person to observe microorganisms
Anton leeuwenhoek
He’s the first person to shape protozoa, bacteria, parasite
Anton van leeuwenhoek
Control center of the cell
Nucleus
He discovered nucleus
Robert Brown
They enunciated cell theory
schleiden and schwann
He published first comprehensive human histology
jacob henle
He said that human body as cell state
Rudolph virchow
He listed specialize categories of cell
Rudolph virchow
What century did microtome boomed
19th century
It is an instrument for preparing tissues section for study
Microtome
They pioneer developments in microscopy immersion lenses and apochromatic lenses
carl zeiss and ernst abbe
He constructed the first electron microscope
ernst ruska
Microscopy for the examination of treponema pallidum
Dark field microscopy
It is for unstained living organisms
darkfield
It is the causative agent of syphillis
Treponema pallidum
It is the causative agent of syphillis
Treponema pallidum
It is a light microscope with dark field apparatus
Darkfield microscopy
This microscopy brights or glows brightly the specimen
Dark field microscopy
It describes an illumination technique used to enhance the contrast in unstained sample
Dark field
This produces the classic appearance of a dark, almost black, background with bright objects on it
Dark field
It works by illuminating the sample with light that will not be collected by the object lens, thus will not form part of the image
darkfield
Strong oblique life that does not enter objective lens
Dark field
Shape of the treponema pallidum
spiral or spirochete
This microscope is for moving, living and unstained cells
Phase contrast
This my Costco has a cellular detail that are not visible with a simpler Bright Field microscope
Phase contrast
It is an optical microscope technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image
phase contrast
Specimen in phase contrast
Trichomonas vaginalis
Specimen in phase contrast
Trichomonas vaginalis
microscope for identification of crystals
polarizing microscope
It is a microscope of the interaction of plane polarize light with a doubly refracting
polarizing microscope
This doubly refracting is called
birefringent
This microscope has a specimen to produce two individual wave component
polarizing microscope
These are two individual wave components
Ordinary and extraordinary ray
Crystals such as
Kidney and urine
It is for fluorescent dyes stained organism
fluorescent microscope
Stain for fluorescent microscope
Fluorochrome
It’s light or energy is extreme or rich in UV radiation
fluorescent microscope
This microscope equipped with exciter filter
fluorescent microscope
It has a barrier filter Between
Objective and observers eyes
Microscope that is useful in many diagnostics
fluoroscent microscope
It is for lattice imaging
Transmission electron microscope
TEM has a resolution of
Less than 0.2 nanometer
What is the disadvantage of TEM
Silhouette picture
Source of electrons in TEM
Magnetic lenses
It has electron micrograph
TEM
chemical that preserve the lipid
Osmium tetroxide
Chemical that preserve the proteins
Paraformaldehyde
It is for studying the texture, topography and surface feature
Scanning electron microscope
Scanning electron has a resolution of
10 nm
It is for detailed surface structure and has 3-D image
Scanning electron microscopy
It is for detailed surface structure and has 3-D image
Scanning electron microscopy
Microscope that has a total magnification of 1500
bright field, dark field, fluorescence, phase contrast, nomarski differential interference and confocal
Microscope that has a resolving power of 100 to 200 nm
Bright Field, darkfield, phase contrast, fluoruscence, nomarski differential interference and confocal scanning
Ultraviolet total magnification
2500
Resolving power of ultraviolet
100 nm
Extensively used for visualization of micro organisms usually necessary to stained specimens for view
brightfield
Used for viewing live microorganisms, particularly those with characteristics morphology
Dark field
It is to differentiate 2 specimen
resolving power
Improve resolution over normal light microscope and largely replaced by electron microscope
Ultraviolet
Uses Florissant staining and it is useful in many diagnostic procedures for identifying micro organisms
Florescence
It is used to examine the structures of living micro organisms and does not require staining
phase contrast
Used to examine structures of micro organisms and produces sharp multicolored image with three dimensional appearance
nomarski differential interference
Used to examine structures of micro organisms and produces sharp multicolored image with three dimensional appearance
nomarski differential interference
Use the exam in structures of my card on easels and individual micro organisms with in mixtures of various types of micro organisms
confocal scanning
These microscopes has three dimensional appearance
nomarski differential interference, confocal scanning and SEM
Used to view ultrastructure of microorganisms including viruses and much greater resolving power and useful magnification that can be achieved with light microscopy
TEM
Used for showing detailed surface structures of microorganism and produces a three dimensional image
SEM
