Endocrine System: Unit Review and Quiz
|
Unit Review
Here is what we have learned from this unit:
- Chemical messengers from the endocrine system help regulate
body activities. Their effect is of longer duration and
is more generalized than that of the nervous system.
- Neurons are the nerve cells that transmit impulses. Supporting
cells are neuroglia.
- Endocrine glands secrete hormones directly into the blood,
which transports the hormones through the body.
- Cells in a target tissue have receptor sites for specific
hormones.
- Many hormones are regulated by a negative feedback mechanism;
some are controlled by other hormones; and others are affected
by direct nerve stimulation.
- Even though the endocrine glands are scattered throughout
the body, they are still considered to be one system because
they have similar functions, similar mechanisms of influence,
and many important interrelationships.
- Major glands include: pituitary gland, thyroid gland,
parathyroid gland, adrenal (suprarenal) gland, pancreas,
gonads (testes and ovaries), pineal gland, and other endocrine
glands.
Quiz
To test how much you have learned from this unit, two types
of quizzes have been created. The first type is a true-false
quiz. The quiz questions are grouped into several 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
Next button (a right-pointing arrow icon located in the Title
Bar) to proceed to the next page.
The second type is a drag-and-drop quiz, in which, by using
the mouse pointer, you drag a textual or graphic element to
a target area to show your knowledge of the material covered
in the unit. Note that the object you are dragging will snap
back to its original position until it is placed in the correct
target area. Try to drag the object as close to the center
of the target area as possible so that the object will snap
to the target area when you chose a correct answer.
