Bone, Ligaments, and Cartilage Flashcards
1
Q
Skeleton is made of these three connective tissue types
A
Bone, ligaments, cartilage
2
Q
Function and Traits of Ligaments
A
- Attach bone to bone
- Support joints
- Dense and fibrous, little stretch. Due to being mostly collagen with little elastigen
3
Q
Function and Traits of Cartilage
A
- Protects bones by taking impact and springing back up (resilient material)
- Surrounded by the perichondrium
- High water content
- Fibrocartilage, Hyaline, Elastic Cartilage
4
Q
Fibrocartilage
A
- Strongest, densest cartilage
- Found in intervertebral disks and menisci
5
Q
Hyaline
A
- Covers and protects the ends of long bones, as well as forming rings around the respiratory system to prevent the trachea from collapsing
- Found in growth plates growing pre-bone, as well as ribs
6
Q
Elastic Cartilage
A
- Most flexible cartilage type
- Found in places like the tip of the nose and the outer ears
7
Q
Bone is made of these two cell types
A
- Bone matrix
- Bone cells
8
Q
Bone Cell Types
A
- Osteoblasts
- Osteoclasts
- Osteocytes
- Osteogenic cells
9
Q
Osteogenic Cell
A
Stem cells that become osteoblasts.
10
Q
Osteoblast
A
Produce and secrete bone matrix, develop into osteocytes.
11
Q
Osteocyte
A
Keeps bone matrix healthy. This is the final phase of a bone cell’s life.
12
Q
Osteoclast
A
Develops separately from other bone cell types, reabsorbs bone so that its material can be used.
13
Q
Bone Types
A
- Hard/compact
- Spongy
14
Q
Compact Bone
A
- Harder
- Made up of osteons (haversian systems), circumferential lamellae, and interstitial lamellae
- Forms the shaft and ends of bones
- Wraps around and contains the marrow space
15
Q
Osteons
A
Made up of:
- Lamellae
- Lacunae
- Central/haversian canal containing blood vessels, lymph vessels, and a nerve
