Compound microscopes

have two sets of lenses that collect and focus light as it is transmitted trough the sample

ocular lenses

the lenses you look through to see the specimen

Binocular

microscopes with two ocular lenses

ocular lenses magnify the image:

10X

The objective lenses names and magnification

scanning power (4X), low power (10X), and high power (40X)

Resolution

the ability to reveal detail or to distinguish two objects that are close to each other

Contrast

the differential absorption of light by different parts of the object under study

coarse adjustment knob

moves stage relatively large distance when turned

fine adjustment knob

moves stage relatively small distance to shape focus

iris diaphragm

Helps obtain the best contrast possible

Working distance

distance between slide and bottom of scanning lens

Parafocal

stays mostly in focus when you change objectives.

Paracentric

stays mostly in center when you change objectives

Total magnification formula

Total magnification = objective magnification x ocular magnification

the dorsal cavity includes the:

cranial and vertebral cavity (canal)

the ventral body cavity includes the:

thoracic and abdominopelvic cavity + serous membranes

Thoracic cavity includes the:

pericardial (surrounding the heart) and pleural (surrounding the lungs) cavities.

The mediastinum

The region in the middle of the thoracic cavity between the lungs. It contains the pericardial cavity, great vessels and portions of the trachea, esophagus and thymus.

Abdominopelvic cavity includes the:

abdominal cavity (stomach and intestines) + lower pelvic cavity (bladder and reproductive organs).

Serous membranes

Line the ventral body cavities and organs inside. Are specialized moist membranes between organelles.

Serous Fluid

Lubricating fluid between the two serous membranes

Parietal serosa

Membrane lining the cavity wall (part of serous)

Visceral serosa

Membrane covering the organs

Mesothelium

Layer of squamous epithelium that covers the sheet of connective tissue that makes up the serous membrane

Inside + Outside Layer of heart + name of cavity

visceral and parietal pericardium, pericardial cavity

Inside + Outside Layer of lung + name of cavity

visceral and parietal pleura, pleural cavity

Inside + Outside Layer of stomach + name of cavity

visceral and parietal peritoneum, peritoneal cavity
