Muscular System: Unit Review and Quiz

Unit Review
Here is what we have learned from this unit:
- One of the most predominant characteristics of skeletal
muscle tissue is its contractility and nearly all movement
in the body is the result of muscle contraction.
- Four functions of muscle contraction are movement, posture,
joint stability, and heat production.
- Three types of muscle are skeletal, smooth, and cardiac.
- Each muscle fiber is surrounded by endomysium. The fibers
are collected into bundles covered by perimysium. Many bundles,
or fasciculi, are wrapped together by the epimysium to form
a whole muscle.
- Muscles are attached to bones by tendons.
- Muscle features such as size, shape, direction of fibers,
location, number of origin, origin and insertion, and action
are often used in naming muscles.
- Four major muscle groups of the body include:
- Muscles of the head and neck;
- Muscles of the trunk;
- Muscles of the upper extremity; and
- Muscles of the lower extremity.
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.
