Exam 2 Slide show Skeletal Tissue (pt1) Flashcards
What are the functions of cartilage?
- Comprises parts of the skeleton where flexibility is required
- Articular surfaces
- Template for bone formation
What are the two articular surfaces of cartilage?
Smooth and low friction
The younger a person is, the _____ cartilage they have.
More
What consists of a dense network of collagen fibers and elastic fibers embedded in a jelly-like ground substance of chondroitin sulfate
Cartilage
What gives cartilage its strength?
Collagen fibers
What gives cartilage its resilience?
Chondroitin sulfate
Where do chondrocytes reside?
In lacunae
Cartilage is capable of enduring more stress than either what?
Loose or dense connective tissue
Most cartilage is covered by a dense, irregular connective tissue called
Perichondrium
Does cartilage have blood vessels?
No and it ONLY has nerves in the perichondrium
What are the three types of cartilage?
- Hyaline cartilage
- Fibrocartilage
- Elastic Cartilage
After becoming vasularized, the perichondrium becomes what?
Periosteum
What obtains nutrients and dispose of wastes by diffusion
Chondrocytes
What is the most abundant type of cartilage in the body?
Hyaline cartilage
How does hyalin cartilage appear in the body?
As a bluish-white shiny substance
Name the type of cartilage that has the strongest form of cartilage
fibrocartilage
Name the type of cartilage that is the template for bone formation
hyaline cartilage
Characterize cartilage with regard to: nerve supply, rate of growth, rate of healing, vascular supply
Has no nerves (except in perichondrium), grows slowly, poorly healing if heals at all, non-vascular
How is diffusion in cartilage aided?
the chondrocytes are aided by the pumping action generated by compression of articular cartilage or flexion of elastic cartilage
Name the type of cartilage that is Commonly disk shaped segment between bone
fibrocartilage
Name the type of cartilage that forms articular surfaces
hyaline cartilage
Name the type of cartilage that has the greatest tensile strength of the different forms of cartilage:
fibrocartilage
Name the type of cartilage that lacks a perichondrium wherever it is found
fibrocartilage
State the type of cartilage commonly found in the external ear and auditory canal
elastic cartilage
Compare hyaline cartilage and fibrocartilage with regard to the existence and extent of a perichondrium
Hyaline cartilage has a perichondrium whereas the fibrocartilage does not
