What are the regular, alternating indentations and protrusions of the keratinized layer of the epithelium in the image?
In the center of the image is a circular profile. What is it?
A capillary in cut in cross-section.
The long, thin profile in the center of the micrograph is a:
The tubules in the figure are surrounded by many small, roughly-circular profiles. What are they?
capillaries made from simple squamous epithelium
Can you recognize the tissue in this image?
Cells of epithelia differ in their volume because:
they contain varying amounts of "machinery" depending upon their function
Fresh cartilage, when viewed with the naked eye, looks like:
pliable, white rubber
If a bone is fractured, there is usually a significant collection of blood (forming a hematoma) in the tissues around the fracture. Why would that be the case?
Bone is very vascular (that is, it contains many blood vessels).
If a slice of a tissue demonstrated a series of circles all of which were the same size, what might the original three-dimensional object have looked like?
If a slice of tissue demonstrated a mixture of circular and oblong profiles, what might the original thr-dimensional object have looked like?
Tubes cut at various angles
If an observer were standing on a sheet of simple columnar epithelium, what would it look like?
A tile floor
The image is a section through kidney tissue. How is this different than previous examples that you have seen?
It is a longitudinal section instead of a cross-section.
Light-skinned people have an almost pink tint to their skin. This is due to
Blood in vessels in the deeper layers.
The keratinized layer of epithelium would probably be thickest on the:
palms of the hand
Which of the following would be a "surface" in the body?
Covering of the ventral surface of the eye
Which of the following would you predict would be true of the epithelial lining of the nose?
Contains cells that are specialized for secretion
