Functions or Purposes of the Skeletal System
- Support: The skeletal system provides a framework that supports the body and cradles soft organs. It helps maintain the body's shape and posture.
- Movement: Bones act as levers for the skeletal muscles. When muscles contract, they pull on bones to create movement at joints.
What is a Fracture?
A fracture is a break in the continuity of a bone. Fractures can occur due to various factors, including trauma, overuse, or medical conditions that affect bone density. They can range from a thin crack (stress fracture) to complete breaks that may involve fragments of bone being displaced.
One Disease or Condition that Can Affect the Skeletal System
Osteoporosis: This condition is characterized by a decrease in bone density, making bones more fragile and susceptible to fractures. It commonly affects older adults, particularly postmenopausal women, due to hormonal changes that impact bone remodeling.
How the Skeletal and Muscular System Work Together
The skeletal and muscular systems work in tandem to facilitate movement and maintain posture. Muscles are attached to bones via tendons; when a muscle contracts, it pulls on the bone, causing movement at the joint. This system allows for a wide range of motions, and the skeletal framework provides stability and support for the muscles to function effectively. Moreover, the coordination of muscles and bones is essential for activities like walking, running, and lifting.
