1
Q
What initially make up the human skeleton, then is replaced by bone?
A
Cartilages and fibrous membranes
2
Q
What is Skeletal cartilage made of?
A
A variety of cartilage tissue sculpted to fit location and function
3
Q
Features of Skeletal cartilage?
A
- Mostly water
- resilient
- No nerves and blood vessels
4
Q
What is the perichondrium?
A
- layer of dense regular regular tissue
5
Q
What does the perichondrium do?
A
- Act as reinforcement to resist expansion, when cartilage is compressed
6
Q
What does the perichondrium surround?
A
- Cartilage
7
Q
What is Skeletal cartilage thickness limited by?
A
- distance nutrients can diffuse through the matrix
8
Q
What are three types of Cartilage tissue?
A
- Hyaline
- Fibrocartilage
- Elastic
9
Q
What do all cartilage tissue have?
A
- chondrocytes in a lacunae with an Extracellular matrix in a jelly like substance and fibers
10
Q
What does hyaline cartilage look like?
A
- Frosted glass
11
Q
Shape of hyaline cartilage chondrocytes?
A
- spherical
12
Q
Features of hyaline cartilage?
A
- Provide support (flexibility and resilience)
- most abundant
- only fiber type is collagen
13
Q
What does Skeletal hyaline cartilage include?
A
- articulate cartilage
- costal cartilage
- respiratory cartilage
- nasal cartilage
14
Q
What does articulate cartilage do?
A
- cover end of most bones at moveable joints
15
Q
What does costal cartilage do?
A
- Connect the ribs to the sternum (breastbone)
16
Q
What does respiratory cartilage do?
A
- form larynx skeleton (voicebox) and strengthen other respiratory passageways
17
Q
What does Nasal cartilages do?
A
- support external nose
