Connective Tissue

Question 1

Answer 1

• Variations in blood supply
• Extracellular Matrix

Question 2

What are some functions?

Answer 2

Protecting, supporting, cushioning and insulating other body tissues

Question 3

What are extracellular matrix?

Answer 3

Consists of a structureless ground substance and fibres

Question 4

What is the ground substance of the matrix?

Answer 4

Composed largely of water + cell adhesion proteins + large polysaccharide molecules.

Question 5

What is the purpose of the cell adhesion?

Answer 5

Serves as glue that allows the connective tissue cells to attach themselves to the matrix fibers embedded in the ground substance.

Answer 6

All connective tissues consists of living cells surrounded by extracellular matrix.

Answer 18

Collagen

Question 19

The external ear maintains its shape nicely because it consists of:

Answer 19

Elastic Cartilage

Question 20

What are the cells which secrete and maintain the matrix in your intervertebral discs?

Answer 20

Chondrocytes

Question 21

The bundle of collagen fibres that attaches bone to bone at a joint is called a(n)

Answer 21

Ligament

Question 22

What is a ligament?

Answer 22

Connection between bone and bone

Question 23

What is a tendon?

Answer 23

Connection between bone and muscle

Question 24

The bundle of collagen fibres at the end of a skeletal muscle that attaches the muscle to bone is called a(n)

Answer 24

Tendon

Question 25

Tendons and ligaments are made of tissue that has high tensile strength. What type of tissue makes up tendons and ligaments?

Answer 25

Dense Tissue

Question 26

Which of the following cells consists of molecules of fat?

Answer 26

Adipocytes

Question 27

Osteocytes are stationary cells sitting in small depressions in the bone matrix. These small depressions are called __________.

Answer 27

Lacunae

Question 28

In order to hold tissue together, fibers are involved. Which of the following types of fibers hold tissue together by forming a net‐like arrangement of fibers?

Answer 28

Reticular

Question 29

Which of the following cells are associated with a gel matrix?

Answer 29

Chondrocytes

Question 30

Which of the following connective tissue cells consists of a matrix of gelatinous material?

Answer 30

Cartilage

Question 31

Which of the following connective tissue cells consists of a matrix of fibers?

Answer 31

areolar, adipose, reticular, dense

Question 32

How is blood different from other connective tissues?

Answer 32

1. The blood does not have fibers in its matrix except when it is clotting. 2. It does not act as a cushion between different organs. Blood transports different substances between organs, but it does not have a cushioning effect, unlike some connective tissues like areolar tissue and adipose tissue.

Question 33

Does Blood have an extracellular matrix?

Answer 33

Yes, it has a fluid extracellular matrix - plasma

Question 34

Can you select the differences between ligament and tendon?

Answer 34

- Ligaments are stretchier than tendons -Tendons connect muscles to bones, and ligaments connect bone to bone

Question 35

What do ligaments connect to?

Answer 35

Bone to bone

Question 36

What do tendons connect?

Answer 36

Muscle to Bone

Question 37

What type of tissue are ligaments and tendons?

Answer 37

Dense connective tissue (in which the extracellular matrix is densely packed with collagen fibres)

Question 38

How is cartilage similar to bone?

Answer 38

- Specialised connective tissue -

Question 39

Which of the following is a difference between areolar tissue and adipose tissue?

Answer 39

Adipose tissue is used to store energy, while areolar tissue is not. The innumerable adipocytes in adipose tissue store large quantities of fat as a storehouse of energy.
