Musculoskeletal System (BATES) Flashcards
What are synovial joints
Bones of these joints do not touch each other, and the joint articulations are freely movable
What are examples of ball and socket joints
Shoulder
Hip
What are examples of hinge joints
Interphalangeal joints of hand and foot
Elbow
What are the different types of condylar joints
Knee
TMJ
What is the definition of hinge joints
They are flat, planar, or slightly curved allowing only a gliding motion in a single plane
*flexion and extension of the elbow
What is the definition of condylar joints
Have articulating surfaces that are convex or concave
*allow for flexion, extension, rotation and motion in the coronal plane
What are cartilaginous joints
- Fibrocartilaginous disc separates the bony surfaces of these joints
*allow for a small amount of movement
What are examples of cartilaginous joints
- Symphysis pubis
- Sternomanubrial joint
What are fibrous joints
- Have intervening layers of fibrous tissue or cartilage that hold the bones together
*no movement
What are examples of fibrous joints
Sutures of the skull
What are articular structures
- Joint capsules
- Articular cartilage
- Synovium and synovial fluid
What are extraarticular structures
- Ligaments
- Tendons
Pathology of articular structures involves what
- Swelling and tenderness of the joints
- Crepitus
- Instability
- Locking
*limits both active and passive range of motion
Pathology involving extraarticular structures involve what
- Rarely cause intraarticular joint swelling
- Instability
- Or tenderness
*limits active ROM only
Generalized aches and pains are called what
Myalgias
