Lab Anatomy and Cell Biology Flashcards

Vocabulary flashcards covering cell transport mechanisms, anatomical terminology, lab safety, and compound microscope components based on lab notes.

Filtration

The movement of water and solutes through a membrane from an area of higher pressure to an area of lower pressure.

Hydrostatic pressure

The pressure exerted by liquids, which in the human body is provided by the pressure of blood.

Filtrate

The fluid and dissolved substances that pass through a membrane during the process of filtration.

Lugol's iodine reagent

A solution added to test for the presence of starch, which turns a blue/black color when starch is present.

Isotonic concentration

The concentration of a solution (such as corn syrup) that produces zero percent change in the mass of a cell or egg.

Percent change in mass formula

Calculated as $\left(\frac{\text{Change in Mass}}{\text{Initial Mass}}\right) \times 100\%$

Axillary

The anatomical term for the armpit.

Brachial

The anatomical term for the arm.

Popliteal

The anatomical term for the posterior region of the knee.

Gluteal

The anatomical term for the buttocks.

Ophthalmic

The anatomical term referring to the eyes.

Cervical

The anatomical term referring to the neck.

Frontal plane

A plane that divides the body into anterior and posterior portions.

Horizontal plane

A plane that divides the body into superior and inferior portions.

Midsagittal plane

A plane that divides the body into equal right and left portions.

Sagittal plane

A plane that divides the body into right and left portions.

Ocular lens

Two lenses located in the binocular tube of a microscope that magnify the image by $10\times$.

Iris diaphragm

A component of a compound microscope that controls brightness and the amount of light passing through the specimen.

Fine adjustment knob

A microscope control used to fine-tune the focus of the image.

Coarse adjustment knob

A microscope control that focuses the image by raising and lowering the body tube.

Condenser

A group of lenses on a microscope that concentrate and direct the light beam from the lamp to the specimen.

Revolving nosepiece

The part of a microscope that holds the objective lenses and allows the user to switch between them.

Mechanical stage adjustment knob

A control that holds microscope slides in place and moves them across both horizontal axes.

10% bleach solution

A cleaning solution used to wash lab work areas if specimens, preserved animals, or fresh animal tissues have been used.
