PHYSICAL WELLNESS
the body’s flexible connections
JOINTS
Joints are like hinges, pivots, or sliding doors in your body — they connect bones and allow movement. Some joints are highly flexible (like your shoulders), while others are more stable (like your skull), depending on their function.
Connect bones to each other
Allow a range of movement (bending, twisting, rotating)
Provide stability to the skeletal system
Absorb shock during activities like walking, running, or jumping
Help maintain proper alignment of the skeleton
JOINT BASICS
Common Terms + Simple Definitions
Here’s a mini glossary for joint related words you’ll see throughout the site:
Joint - Place where two or more bones meet
Ligament - Connects bone to bone and stabilizes the joint
Tendon - Connects muscle to bone to create movement at the joint
Cartilage - Smooth tissue that cushions and protects joint surfaces
Synovial Fluid - Lubricating fluid inside joint capsules to reduce friction
Ball-and-Socket Joint - Allows movement in many directions (e.g., shoulder, hip)
Hinge Joint - Allows movement in one direction like a door (e.g., elbow, knee)
WHAT JOINTS WORK WITH
JOINTS + OTHER SYSTEMS
Bones → Provide the rigid structure that joints connect
Muscles → Pull on bones across joints to create movement
Ligaments → Stabilize joints by connecting bones to bones
Tendons → Help transfer muscle force across joints
Cartilage → Cushions joints and reduces friction during movement
Nervous System → Sends signals to coordinate movement and maintain balance
HealthY JOINTS…
Joints are the flexible points that make movement possible. Healthy joints allow fluid motion, protect bones from wear, and keep the body aligned and balanced. Without them, even the strongest muscles and bones couldn’t function effectively.
