Name the 3 types of joints
|
Fibrous, cartilaginous & synovial
|
|
|
What type of joint is least mobile?
|
Fibrous
|
|
|
Name 2 examples of Fibrous joints.
|
Suture, Syndesmosis or gomphosis
|
|
|
What type of joint is somewhat movable, but can't move freely?
|
Cartilaginous
|
|
|
Name an example of a cartilaginous joint.
|
Synchondrosis (hyaline cartilage) or Symphysis (fibrocartilage)
|
|
|
What type of joint is free moving?
|
Synovial
|
|
|
What makes up a synovial joint?
|
It is a capsule filled with synovial fluid around a joint. Also has Hyaline cartilage on bones.
|
|
|
Name the 6 types of Synovial joints.
|
Plane, Ball and socket, Hinge, pivot, condyloid and saddle.
|
|
|
How many layers does an articualr capsule of a synovial joint have? and what are they made of?
|
2 layers. Fiberous capsule- made of dense irregular connective tissue (continuous with periosteum). Synovial membrane-inner layer of loose connective tissue, secretes synovial fluid.
|
|
|
What does synovial fluid do?
|
It acts as a lubricant of the joint, it fills the cavity and bears some of the weight and nourishes and protects the cartilage.
|
|
|

|
What are the 2 types of arthritis?
|
Acute- short, predictable cycles, usually due to infection.
Chronic- long lasting, often from wear and tear. |
|
|
What are some of the causes of Chronic Arthritis?
|
Wear and tear of joints, degeneration of articular cartilage, or exposed bones can thincken and form bony spurs.
|
|
|
What is Rheumatoid Arthritis? and what kind of arthritis is it? (acute or chronic)
|
Chronic. Its a chronic inflammatory disorder (an autoimmune disease). There is no cure.
|
|
|
What happens to the joint in rheumatoid arthritis?
|
inflammation in the joint causes fluid to accumulate and pain is caused by the pressure.Over time granulation tissue (pannus) and scarring replace the joint tissue. This causes a loss of function.
|
|
|
What is Gouty arthritis?
|
Uric acid is produced too much or the person is unable to eliminate it properly and crystals form. They deposit in soft tissues and cause pain and swelling.
|
|
|
