BIOL 2457 – Joints Section | A+ Graded Q&A with
Anatomy and Clinical Relevance on Articulations,
Movements, and Joint Types
ALL limb joints are what kind of joints? (fibrous, cartilaginous, or synovial) - ✔✔Synovial joints
What are the 6 structural features of synovial joints? - ✔✔1) Articular cartilage
2) Joint cavity
3) Synovial fluid
4) Articular capsule
5) Reinforcing ligaments
6) Nerves & blood vessels
What is the articular cartilage in a synovial joint? - ✔✔Cartilage that acts like a shell that
covers the bone surfaces
- Made of hyaline cartilage
What is the joint cavity in a synovial joint? - ✔✔It's the space/cavity that contain the synovial
fluid
What is the synovial fluid in a synovial joint? - ✔✔It's a slippery fluid that:
- Reduces friction between articular cartilages
- Nourishes chondrocytes (cells that make cartilage)
What is the articular capsule in a synovial joint and what 2 structures does it include? - ✔✔It
encloses the joint cavity and includes:
1) Fibrous capsule
2) Synovial membrane
, The synovial membrane is a part of the articular capsule of the synovial joint. What does it
do? - ✔✔It's the actual membrane that encloses the joint cavity and it PRODUCES synovial
fluid
The fibrous capsule is a part of the articular capsule of the synovial joint. What does it do? -
✔✔A capsule that embraces both articulating bones in order to PREVENT it from pulling apart
What are the reinforcing ligaments in a synovial joint? - ✔✔Ligaments that strengthen and
reinforce the joint
What do nerves and blood vessels do for synovial joints? - ✔✔It monitors and gives nutrition
to the joint
What 2 structures are NOT direct parts of synovial joints but are closely associated? - ✔✔1)
Bursa
2) Tendon sheaths
What do bursa and tendon sheaths do for synovial joints? - ✔✔They BOTH reduce friction,
but with different structures
- Bursa are flattened SACS that are between joints to reduce friction
- Tendon sheaths are cylinders of connective tissue that WRAPS around a TENDON to reduce
friction
- Remember that tendons attach bones to muscles so it's found in areas with a lot of
movements like arms and legs
Skeletal muscles are attached to bones at AT LEAST what 2 points? - ✔✔1) Origin: attachment
site that does NOT move during contraction
2) Insertion: attachment site that DOES move during contraction
