Answer 5

Mesenchyme
→Hemocytoblasts
→Blood

Question 6

Mast cells produce what components and Neutrophils of Connective Tissue Proper

Answer 6

• Mast cells produce heparin and histamine
• Neutrophils are the most common white blood cell found in connective tissue

Question 7

- Are referred to as “white fibers”
- Coated with glycoprotein for strength
- Found in the lungs are arteries

Answer 7

Collagenous – (b) Are referred to as “white fibers”
Reticular – (a) Coated with glycoprotein for strength
Elastic – (c) Found in the lungs and arteries

Answer 8

Liquid – (d) Blood
Gel-like – (c) Connective tissue proper
Semi-solid – (a) Cartilage
Solid - (b) Bone

Question 9

Identify the FALSE statement regarding loose connective tissue.
- Areolar tissue is avascular
- Reticular tissue forms a structural framework called a stroma around soft organs
- Adipose tissue gives shape to the body
- All of the above are true statements

Answer 9

a. Areolar tissue is avascular

(FALSE- areolar tissue is very vascular)

Question 10

- Dense regular connective tissue contains a small amount of fibroblast
- Dense regular connective tissue provides strength in one direction
- Dense irregular connective tissue provides strength in multiple directions

Answer 10

Dense REGULAR connective tissue provides strength in ONE direction

Dense IRREGULAR connective tissue provides strength in MULTIPLE direction

Question 11

What types of tissues are present in cartilage?

Answer 11

• Collagen
• Elastic

Question 12

Explain why the sensation of pain can be felt in cartilage when there is no direct nerve supply.

Answer 12

The pain is felt due to the inflammation around the injured site.

Question 13

Match the type of cartilage with the correct description: Hyaline cartilage, Elastic cartilage, Fibrocartilage.

Answer 13

Hyaline cartilage - Perichondrium lacking around articular cartilage.

Elastic cartilage - cells always surrounded by perichondrium.

Fibrocartilage - found in the pubic symphysis
