Nose piece
Known as the body and carries optical parts in the upper part of the microscope
Head
Also known as the “ocular”
Eyepiece

FLUORESCENE MICROSCOPE
Hooke devised the compound microscope and illumination system (1665) and the best microscope of his time
COMPOUND MICROSCOPE
Knobs that move the condenser up and down thus controlling the focus of light on the specimen
Condenser focus knobs
Controls how far the stages should go preventing the object lens from getting too close to the specimen slide and prevents specimen slide from coming to far up and hitting the objective lens
Rack stop
Study of cells
CYTOLOGY

Embryology
Closer to the feet or lower than another structure in the body
Inferior
Study of structural changes caused by disease
PATHOLOGICAL ANATOMY
Study of internal structures visualized by x-ray
RADIOGRAPHICAL ANATOMY
Study of anatomical structures at a sub-cellular level
MOLECULAR BIOLOGY

Works together to maintain cellular homeostasis and perform essential life activies
Structure and Basic Functions
Surrounds the cell in a selective barrier between interior and exterior
Cell membrane
Rigid cell wall, may have flagella
Animal cell
Composed of protein filaments and regulates cell shape
Cytoskeleton
Give the three protein filaments
Microtubules, Microfilaments, Intermediate filaments
Study of internal structures as they relate to the overlying skin
SURFACE
Used to view, magnify, and produce an image from a specimen placed on the side
OPTICAL PARTS
Also known as the iris and found under the stage of the microscope. Its primary role is to control the amount of light that reaches the specimen
Diaphragm
Image appears to be enlarged
Magnification
Condenser specially designed for high-quality microscopes. allows condenser to be movable and allows very high magnification
