Cartilage Flashcards
1
Q
What are the traits of cartilage tissue?
A
- Smooth
- Elastic
- Resilient
2
Q
What does cartilage tissue do in terms of the skeleton?
A
- Reduces friction
- Limits compression (gives a larger surface area)
3
Q
What nerves and blood run through cartilage?
A
- Nothing
- Pain and bleeding come from the nearby tissues
- No regeneration after damage
4
Q
What are the layers of cartilage?
A
- Superficial (tangential) layer
- Transitional layer
- Deep layer
5
Q
What does the superficial / tangential layer of cartilage do? How is it made up?
A
- Creates a lack of shear
- Densely packed
- Very elastic
6
Q
What does the transitional layer of cartilage do? How is it made up?
A
- Handles compression forces well
- It is the shock absorbing portion of the cartilage
- A gel-like substance lives here
7
Q
What does the deep layer of cartilage do? How is it made up?
A
- Protects the bone’s surface
- Tightly packed
8
Q
What are the two properties of cartilage?
A
- Frictional resistance
- Viscoelastic
9
Q
What is frictional resistance in terms of cartilage?
A
- Resistance of movement (friction) between two bones
- Velocity dependent
- Faster the force applied = more friction created
- Bounce-back happens
10
Q
What is viscoelasticity in terms of cartilage?
A
- Talks about the middle layer of cartilage
- Viscosity: measure of fluid’s resistance to move (cartilage has higher viscosity)
- Elastic: deformed but returns to original shape
11
Q
What is the term that describes cartilage’s increased absorption properties with increased speed or force application? What does this mean?
A
- Frictional resistance
- Faster force applied = less deformities
