The palms face posteriorly with the thumbs pointed toward the body.3. The feet are placed at exactly 45 degrees outward.4. The person is seated with head facing forward.5. Directional terminology refers to the body in this position.
answer
5. Directional terminology refers to the body in this position.
question
Which of the following statements are accurate concerning light microscopy? 1. Tissues are stained with heavy metal salts. 2. It uses a beam of electrons to view cellular structures. 3. It uses acidic and basic dyes to stain structures. 4. It is limited because it cannot produce sharp images of structures within cells. 5. It provides three-dimensional pictures of whole, unsectioned surfaces.
answer
4. It is limited because it cannot produce sharp images of structures within cells.
question
All vertebrates have specific identifying characteristics during some point of development. A partial listing of these characteristics is __________.radial symmetry, vertebrae, and dorsal hollow notochordpharyngeal pouches, dorsal hollow nerve cord, and segmentationtube-within-a-tube, notochord, and ventral hollow nerve cordpharyngeal pouches, coronal symmetry, and anatomical positionventral hollow nerve cord, radial symmetry, and tube-within-a-tube
answer
pharyngeal pouches, dorsal hollow nerve cord, and segmentation
question
Bones lie __________ to muscles.
answer
deep
question
What is the advantage of functional magnetic resonance imaging (fMRI) over positron emission tomography (PET)?fMRI pinpoints smaller brain areas, does not use radioactive tracers, and works faster.fMRI uses radioactive tracers rather than magnets.fMRI is better for observing bones.fMRI is better for determining the age of a fetus.fMRI uses sound waves rather than radioactive tracers.
answer
fMRI pinpoints smaller brain areas, does not use radioactive tracers, and works faster.
question
Sonography is effectively used for viewing all of the following EXCEPT __________.arteriesthe brain and spinal corda developing fetusthe gallbladder
answer
the brain and spinal cordThis is the exception. The brain and spinal cord are not viewed with sonography because sound waves do not penetrate bone

question
During the process of ________, noncellular artifacts can be introduced into histology samples.observationstainingphotographytime
answer
staining
question
The main purpose of fixation isto make an organ easier to section.to preserve the tissue.to stick tissue sections to a glass slide.to mend breaks in tissue sections.
answer
to preserve the tissue.
question
What is the major difference in scanning electron microscopy (SEM) when compared to light microscopy (LM) or transmission electron microscopy (TEM)?SEM is not good at viewing higher magnifications.SEM uses whole, unsectioned surfaces that are covered in carbon and gold dust.The original image is in black and white.SEM uses a beam of light to view specimens.
answer
SEM uses whole, unsectioned surfaces that are covered in carbon and gold dust.
