All flashcards
What is cartilage?
A firm but flexible connective tissue that acts as a cushion between bones, reduces friction, and provides structural support.
What are the main functions of cartilage?
Shock absorption, joint protection, and structural support.
How do ligaments function in the body?
They connect bones to other bones, stabilize joints, and guide movement.
What is a key characteristic of ligaments?
They have a limited blood supply, which results in slow healing after injury.
What do tendons connect?
Tendons connect muscles to bones.
What is the primary function of tendons?
To transfer force from muscle to bone and help maintain joint stability.
What is a joint?
A connection between two or more bones that provides points of movement and structural support.
What are synovial joints?
The most common and complex type of joint in the body, characterized by features like articular cartilage and synovial fluid.
What is the role of articular cartilage?
It covers the ends of bones in a joint, providing a smooth surface and reducing friction.
What does the synovial membrane do?
Lines the joint cavity, produces synovial fluid, and contains blood vessels and nerves.
What is synovial fluid?
A lubricant that reduces friction in joints, provides nutrients to cartilage, and removes waste products.
What is the function of bursae in joints?
Fluid-filled sacs that reduce friction between moving parts and act as cushions.
What is the meniscus?
A structure in some joints that acts as a shock absorber and helps distribute weight evenly.
What are angular movements in joints?
Movements that change the angle between body parts, including flexion and extension.
What is flexion?
A type of angular movement that decreases the angle between two body parts.
What is abduction?
A lateral movement that moves a body part away from the midline.
What is circumduction?
A special movement that involves circular motion of a body part.
What happens during a bicep curl at the elbow joint?
The elbow performs flexion when lifting and extension when lowering.
