Final answer:
The human body can move through various actions facilitated by synovial joints, resulting in gliding, angular, rotational, and special movements. These movements are driven by muscles that flex, extend, abduct, adduct, and rotate the limbs and other body parts. Moreover, the body's cells are also in perpetual motion to maintain vital body functions.
Step-by-step explanation:
The human body can move in a myriad of ways, and these movements are often categorized based on the joints involved and the type of movement performed. For example, synovial joints in the body facilitate a wide range of actions, including but not limited to gliding, angular, rotational, and special movements. Gliding involves flat bone surfaces moving past each other with little rotation, as seen in the joints of the carpal and tarsal bones.
Angular movements like flexion and extension occur in the sagittal plane of motion and involve a change in the angle between bones. Flexion decreases the angle, like bending the elbow, while extension increases it, such as straightening an arm. These movements are evident in joints such as the shoulder, hip, elbow, knee, wrist, and fingers. Special types of angular movements include abduction and adduction, which occur in the coronal plane, moving limbs away from or towards the body's midline. Circumduction combines these actions in a circular motion.
Rotational movement occurs when a bone pivots around its own longitudinal axis, a motion witnessed when shaking the head to indicate "no". Additionally, body movement is not restricted to joints as muscles contract and relax to maintain posture, and various cells, like red and white blood cells, are in constant motion throughout the body.
