CONNECTIVE TISSUE

Question 1

This provides a matrix that supports and physically connects other tissues and cells together to form the organs of the body.

Answer 1

Connective tissue

Question 2

This makes up the extra-cellular matrix.

Answer 2

Protein fibers and ground substance

Question 3

This consists largely of viscous ground substance with few collagen fibers.

Answer 3

Mesenchyme

Question 4

These are undifferentiated and have large nuclei with prominent nucleoli and fine chromatin; often said to be “spindle-shaped” with scant cytoplasm expanded as two thin cytoplasmic process.

Answer 4

Mesenchymal cells

Question 5

These are some of the cells that are potentially useful in regenerative medicine after grafting to replace damaged tissue in certain patients.

Answer 5

Multipotent stem cells

Question 6

These are the key cells in connective tissue proper; they synthesize and secrete collagen and elastin which both forms elastin.

Answer 6

Fibroblasts

Question 7

These are the differentiated cells involve in wound healing.

Answer 7

Myofibroblast

Question 8

These are known as fat cells, found in the connective tissue of many organs.

Answer 8

Adipocytes

Question 9

They have highly developed phagocytotic ability and specialize in turnover of protein fibers and removal of apoptotic cells, tissues, debris, and other particulate materials.

Answer 9

Macrophages

Question 10

These are the oval or irregularly shaped cells of connective tissue, filled with basophilic secretory granules that often obscure the central nucleus.

Answer 10

Mast cells

Question 11

They are also known as white blood cells.

Answer 11

Leukocytes

Question 12

What are the 3 main type of fibers?

Answer 12

Collagen, reticular, and elastic fiber

Question 13

This is a protein molecules made up of amino acids. It provides structural support to the extracellular space of connective tissues. Due to its rigidity and resistance to stretching, it is the perfect matrix for skin, tendons, bones, and ligaments.

Answer 13

Collagen

Question 14

This network acts as a supporting mesh in soft tissues such as liver, bone marrow, and the tissues and organs of the lymphatic system.

Answer 14

Reticular fiber

Question 15

Its function is to provide elasticity and resilience to the tissues.

Answer 15

Elastic fiber

Question 16

These are short lived cells that differentiate from B lymphocytes and are specialized for the abundant secretion of specific antibodies (immunoglobulins)

Answer 16

Plasma cells

Question 17

This is the watery, largely unstained extracellular material that is more abundant than fibers in some types of connective tissue proper.

Answer 17

Ground substance

Question 18

This is usually classified as loose or dense according to the amount of collagen and ground substance present.

Answer 18

Connective tissue proper

Question 19

This has relatively more ground substance than collagen, and it typically surrounds small blood vessels and occupy areas adjacent to other types of epithelia.

Answer 19

Loose connective tissue

Question 20

This is filled primarily with randomly distributed bundles of type I collagen, with some elastic fibers, providing resistance to tearing from all directions as well as some elasticity.

Answer 20

Dense irregular connective tissue

Question 21

This is a gel-like connective tissue with few cells found most abundantly around blood vessels in the umbilical cord.

Answer 21

Mucoid tissue
