TIP: CHANGE UR SETTINGS TO ANSWERING WITH TERM AND WRITING! | (unit 1) histology! | microscope run down | activity 1: epithelial tissue, activity 2: connective tissue proper, activity 3: other types of connective tissue, activity 4: muscle tissue, activity 5: nervous tissue | observing: activity 1: epithelial tissue, activity 2: connective tissue, activity 3: muscle and nervous tissue | wrap up

ocular lenses

the eyepieces to look into the sample

objective lenses

lenses that zoom into the slide

slide clip

the clip that keeps your slide/subject in place to be moved and focused on

condenser

lense that captures light underneath the stage

iris diaphragm

the adjustable circular opening within the condenser that controls the amount of light coming in that reaches the slide/specimen

light source

illuminates the specimen with a beam of light

slide mover

holds the specimen allowing you to move the slide left or right to get the proper view of your specimen

light dimmer

controls the amount of light shined upon the specimen, can allow for further detail depending on the brightness or darkness

power switch

turns the microscope on and off

stage

where the slide of your specimen is placed to be looked at

coarse focus

the knob on the side of the microscope that moves the stage up or down madden joke: think big

fine focus

the knob that makes tiny adjustments between the lens and the stage, providing further detail madden joke: tiny tiny touches

organelles

• structures that perform functions in cells, cells = factory, organelles: the machines

• the process: materials enter; different machines / different products bye bye wastes

objective lens red

4 × 10 = 40

objective lens yellow

10 × 10 = 100

objective lens blue

40 × 10 = 100

objective lens black/white

100 × 10 = 1000
