What is the primary function of joints in the skeletal system?

The primary function of joints in the skeletal system is to enable movement between bones. Joints are the points at which two or more bones articulate, allowing for a range of movements facilitated by the structure of the joint. Different types of joints (such as hinge, ball-and-socket, and pivot joints) contribute to specific types of movement, making them crucial for activities such as walking, running, and other physical actions that involve the skeletal system.

While joints play an essential role in movement, it's important to recognize that bones themselves also serve multiple other functions. For example, bones provide structural support for the body and act as a framework that holds organs in place. Additionally, bones are integral to the production of blood cells in the bone marrow and the storage of essential minerals and nutrients, such as calcium and phosphorus. However, these functions are primarily associated with the bones rather than the joints themselves, which are specifically designed to facilitate movement.
