Review
Here is what we have learned from this unit:
- Cancers can be classified based either on histological
type or their primary site (the location where the cancer
originated).
- Derivation of cells and tissues starts with cell differentiation,
which refers to the process of cells becoming arranged into
three distinct germ layers: an outer ectoderm, an inner
endoderm, and a mesoderm in between.
- All of the organs of the body develop or differentiate
from these three primary germ layers.
- Tissue is composed of a group of cells that are similar
in structure and perform one or more common functions.
- Five major categories of cancer, based on their histological
characteristics, are: carcinoma; sarcoma; myeloma; leukemia;
and lymphoma. In addition, there are also some mixed types.
- The most common sites in which cancer develops include
the skin, lungs, female breasts, prostate, colon and rectum,
and corpus uteri.
Quiz
To test how much you have learned from this unit, a true-false
quiz, including ten questions (two questions at a time in
five sets of questions) has been created to give you an opportunity
to reinforce what you have learned.
Since the quiz is created as an incentive for learning, rather
than an objective evaluation of learning results, the score
of the quiz will not be captured and will not be recorded.
Feedback to your answer is provided instantaneously.
These quiz questions are grouped into five sets of two questions
each to reduce the size of the content on each page. When
you finish the questions in one set, click the navigation
arrows in the Title Bar to go to the next page. Please click
