Connective Tissue Lecture

Question 1

Connective Tissue Types

Answer 1

1. Connective Tissue Proper (collagenous CT)
2. Adipose Tissue
3. Cartilage
4. Bone
5. Blood

Question 2

CT Form & Function

Answer 2

• support, protect, and join various organs
• different types of CT perform different functions
• CT= composed of cells and ECM
• ECM = composed of structural fibers and ground substance
• Most CT is of mesodermal origin
• Some of the cells are of hematopoietic origin

Question 3

Mesenchymal tissue

Answer 3

develops from embryonic mesoderm

Question 4

Mesenchyme

Answer 4

• synonymous to primitive mesenchyme
• loosely organized, mainly mesodermal embryonic tissue which develops into connective and skeletal tissues, including blood and lymph

Question 5

Epithelial-Mesenchyme Transition

Answer 5

• refers to the epithelial cells that have lost their characteristics and acquired those associated with cells of mesodermal origin (CT)
• cancer biology focus
