Connective Tissue (Jasmine)

Question 1

What are the main functions of Connective Tissues?

Answer 1

Provide support (bone), Store energy (fat) and transport materials (blood)

Question 2

Where does Connective Tissue derive from?

Answer 2

Mesoderm

Question 3

Differences between Epithelial versus Connective Tissue

Answer 3

Connective tissue is highly vascularized versus Epithelial which is not vascularized. Connective derives from mesoderm and Epithelial derives from ectoderm, endoderm, and mesoderm.

Question 4

Connective Tissue connects the epithelium to the rest of the body. Which is called?

Answer 4

Basal Lamina

Question 5

Classification of Connective Tissue

Answer 5

1. Connective Tissue Proper 2. Fluid Connective Tissue 3. Supportive Connective Tissue

Question 6

Connective Tissue Proper does what?

Answer 6

Connects and protects

Question 7

Fluid Connective Tissues do what?

Answer 7

Transport

Question 8

Supportive Connective Tissues do what?

Answer 8

Provide Structural Support

Question 9

What are the Categories of Connective Tissue Proper?

Answer 9

1. Loose Connective Tissue

• More ground substance, less fibers
• Ex. Adipose Tissue

2. Dense Connective Tissue

• Less ground substance, more fibers
• Ex: Tendons

Question 10

Answer 10

1. Fibroblasts
2. Macrophages
3. Mast Cells
4. Mesenchymal Cells
5. Adipocytes
6. Melanocytes
7. Lymphocytes
8. Microphages

Question 11

What cell is the pointer showing?

Answer 11

FIbroblast

Question 12

What cell is the pointer showing?

Answer 12

Adipocyte

Question 13

Which one is not connective tissue?

Answer 13

A. Simple Cubodial Epithelium

Question 14

What kind of connective tissue is B showing?

Answer 14

Adipose Tissue

Question 15

What kind of connective tissue is found below?

Answer 15

Dense Irregular Connective Tissue

Question 16

What is the structure shown at the pointer?

Answer 16

Nucleus

• Adipose cells push the nucleus to the outside of the ring “signet”

Question 18

What structure is the pointer showing?

Answer 18

Mast Cell

Question 19

Is this Dense Regular Connective Tissue or Dense Irregular Connective Tissue?

Answer 19

Dense Regular Connective Tissue

Question 20

Mast Cells release histamine and other chemical mediators. What are the three functions and purpose of these chemical mediators?

Answer 20

1. Dilate the blood vessels - this allows for blood to go to the injured area ( causes injured area to become red (erythema))

2. Increase permeability of the vessels- allows for proteins and water to enter (causes swelling ((edema))

3. Stimulate Pain- allows one to know that an injury has occcurred

Question 21

1. What kind of cells are shown below? 2. What do they produce?

Answer 21

1. Fibroblast
2. Collagen Fibers

Question 23

What is the function of reticular tissue? Where is reticular tissue found?

Answer 23

Function: Provides Support

Location: Liver, Kidneys, Spleen, Lymph Nodes, Bone Marrow
