THE SKELETAL SYSTEM
Section I. GENERAL
The skeleton forms the framework for the human body. It is composed of
individual bones. These bones meet (are articulated with) each other at joints.
4-2. GENERAL FUNCTIONS
a. Support. In general, the skeleton supports the body.
b. Motion and Locomotion. Because of the joints and the attached skeletal
muscles, the parts of the body can move with respect to each other (motion). Also,
because of such linkages in the lower members, the entire body can be moved from
place to place (locomotion).
c. Protection. Certain parts of the skeleton are structured to protect vital
d. Hematopoiesis. The skeleton is also involved in formation of blood
e. Storage. Moreover, the skeleton stores various minerals.
Section II. TISSUES AND TISSUE PROCESSES OF SKELETAL ELEMENTS
4-3. CONNECTIVE TISSUES
The skeletal elements are made up of several types of connective tissues. In
general, connective tissues tend to connect and/or support. These tissues are
characterized by an extracellular material referred to as the matrix.
a. In the formation of the individual organs known as the bones, bone tissues
make up the main portion of each bone, on an FCT framework.
b. Certain bone surfaces are covered with cartilage connective tissue.
