Microscope and Rat Dissection Flashcards
aorta
Identify part and function
rheostat
alters the current applied to the lamp to control the intensity of the light produced
cutaneous membrane
parietal pleura
Identify part and function
ocular lens
magnifies the image
Identify part and function
arm
supports the body tube
cecum
kidneys
diaphragm
aids in respiration and separates thoracic and abdominal cavity
Identify part and function
objective lens
gathers light from the specimen, magnifies the image of the specimen, and projects the magnified image into the body tube
trachea
Identify yellow area
superior/anterior vena cava
ileum and jejunum
duodenum
visceral pleura
scrotum
Spleen
The spleen has some important functions: it fights invading germs in the blood (the spleen contains infection-fighting white blood cells) it controls the level of blood cells (white blood cells, red blood cells and platelets) it filters the blood and removes any old or damaged red blood cells.
Diaphragm
Identify part and function
course focus knob
moves the stage up and down to bring the specimen into focus in a larger motion
seminal vesicles
Identify part and function
lamp
light source in your microscope
aorta
cardiovascular
Identify part and function
Base
supports microscope
Identify structure and function
iris diaphragm control lever
regulates the amount of light passing through the condenser
light switch
turns light on and off
Identify part and function
mechanical stage control knobs
y axis
x axis
moves the slide across the stage in four directions for focusing
visceral pericardium
Lungs
prostate gland
spleen
serous membrane
vas deferens
submaxillary glands
Identify part and function
mechanical stage
A flat mechanism that sits on top of the stage and allows the viewer to move a specimen small distances - a task that is otherwise difficult at higher magnifications.
parietal peritoneum
urinary bladder
ribs
Identify part and function
stage
The horizontal surface upon which the slide is placed is called the stage.
Identify part and function
substage condenser
This lens system is located immediately under the stage and focuses the light on the specimen
skin
Larynx
identify structure
inferior/posterior vena cava
Identify part and function
fine focus knob
This knob is inside the coarse adjustment knob and is used to bring the specimen into sharp focus under low power and is used for all focusing when using high-power lenses.
Identify part and function
body tube
The body tube is a hollow tube through which light travels from the objective to the ocular.
Structure and function
revolving nosepiece
Several objective lenses of varying magnification and numerical
aperture are mounted on the revolving nosepiece. The nosepiece must click into place for the objective lens to be in proper alignment.
ureters
liver
visceral peritoneum
pancreas
stomach
esophagus
heart
