Answer 2

What holds you together…

Question 3

What are the four major classes or connective tissue?

Answer 3

1. Proper
2. Cartilage
3. Bone (!)
4. Blood (!!)

Question 4

What are connective tissue’s 6 main jobs?

Answer 4

1. binding and supporting
2. protecting
3. insulating
4. storing reserve fluid and energy
5. transporting substances
6. movement

Question 5

What three factors set connective tissue apart from other tissue types?

Answer 5

1. They all develop from MESENCHYME.
2. Different degrees of VASCULARITY (blood flow)
3. Mostly made of non-living material (EXTRACELLULAR MATRIX!

Question 6

What is MESENCHYME?

Answer 6

A loose and fluid type of embryonic tissue

Question 7

What are the two parts of the EXTRACELLULAR MATRIX?

Answer 7

1. Ground Substance – a watery, rubbery unstructured material that surrounds and protects the living cells
2. Fibers – provide support and structure to the otherwise shapeless Ground Substance

Question 8

What are some types of Fibers in the Extracellular Matrix?

Answer 8

• Collagen fibers (strongest and most abundant)
• Elastic fibers (flexible and stretchy, branching framework)
• Reticular fibers (short, finer collagen fibers that form nets around your organs)

Question 9

What are the three main categories of connective tissues cells?

Answer 9

• Immature (Blast) cells – they help build the matrix
• Mature (Cyte) cells – they help maintain the matrix’s heath
• Macrophages – eat bacteria, foreign materials, and dead cells

Question 10

Which kind of fiber does Marfan Syndrome target?

Answer 10

Elastic Fibers…including the ones supporting the heart and aorta, which can be dangerous!
