Connective Tissues

Question 1

Connective Tissue

Answer 1

Most abundant type of tissue in the body, the functions are strength/support, protection, and insulation

Question 2

Extracellular matrix of connective tissue

Answer 2

Has more matrix substance and less cells

Question 3

ECM composition

Answer 3

Collagen, Elastin, Reticular fibers, cells

Question 4

Types of connective tissue

Answer 4

Mesenchyme, Areolar, Adipose, Reticular Tissue, Dense Regular, Dense Irregular, Elastic, Cartilage (multiple types)

Question 5

Mesenchyme

Answer 5

Embryonic tissue, all connective tissues come from this, some remain as stem cells as adults

Question 6

Areolar (structure)

Answer 6

gel-like matrix, scattered fibrous proteins, hyalunic acid

Question 7

Areolar (cells)

Answer 7

Fibroblasts, macrophages/mast cells (immune cells), adipocytes (fat cells)

Question 8

Areolar (functions)

Answer 8

Packing material, space for diffusion, reserve for salts and waters

Question 9

Areolar (locations)

Answer 9

Most widely distributed connective tissue, surround organs and capillaries, attaches epithelium to underlying tissues

Question 10

Adipose (functions)

Answer 10

Energy storage, insulation, supports/protects organs

Question 11

Adipose (Locations)

Answer 11

Subcutaneous (hypodermis), around kindeys, mammary gland

Question 12

Reticular (functions)

Answer 12

support of soft tissue of organ/small blood vessels

Question 13

Reticular (locations)

Answer 13

Lymph nodes, spleen, bone marrow

Question 14

Dense Regular (Structure)

Answer 14

Matrix of parallel fibers, primary fibroblasts

Question 15

Dense Regular (functions)

Answer 15

Tensile strength/stretch resistance in 1 direction

Question 16

Dense regular (Locations)

Answer 16

Ligaments,tendons

Question 17

Dense irregular (structure)

Answer 17

Interwoven fibers, fibroblasts

Question 18

Dense irregular (functions)

Answer 18

Stretch resistance in multiple directions

Question 19

Dense irregular (locations)

Answer 19

Dermis of skin

Question 20

Elastic (functions)

Answer 20

Allows recoil after stretch

Question 21

Elastic (locations)

Answer 21

Walls of large arteries, walls of bronchial tubes

Question 22

Elastic (appearance)

Answer 22

Coiled elastin, elastin fibers parallel

Question 23

Cartilage

Answer 23

Avascular but not completely (used in compresion regions), slow to heal, widely dispersed and each is located in lacuna

Question 24

Hyaline Cartilage (structure)

Answer 24

Matrix is transparent

Question 25

Hyaline Cartilage (function)

Answer 25

Forms embryonic skeleton, allows the growth of long bones

Question 26

Hyaline Cartilage (location)

Answer 26

End of long bones, growth plate, nose, trachea, costal cartilage

Question 27

Elastic Cartilage (structure)

Answer 27

Elastin fibers, lacuna

Question 28

Elastic Cartilage (functions)

Answer 28

Flex, shape retention

Elastic Cartilage (Locations)

Answer 29

External ear, epislotts

Question 30

Fibrocartilage (Functions)

Answer 30

Absorbs compression forces, tensile strength

Question 31

Fibrocartilage (location)

Answer 31

Intervertebral disks, articular disks, pubic symphysis
