Joints serve two critical functions within the skeletal system. According to the provided reference, these are: to allow mobility and to provide protection for vital organs.
Key Functions of Joints
Joints, the meeting points of two bones, are essential for movement and protection.
- Mobility: Joints enable the skeletal system to move.
- Protection: Certain joints create a protective enclosure for internal organs.
Function | Description | Example |
---|---|---|
Mobility | Allows for a range of motion, from simple bending to complex rotations. | Elbow joint allowing the arm to bend. |
Protection | Creates a bony cage or structure to shield vulnerable organs from injury. | Rib cage protecting the heart and lungs. |
Mobility Explained
Without joints, movement would be impossible. Joints enable walking, running, grasping objects, and a multitude of other daily activities. The type of joint dictates the range and type of motion possible.
Protection Explained
Joints like those forming the rib cage offer a crucial layer of defense. The bony structure protects delicate internal organs from external impacts and potential damage.
