Question 1

What are the 4 types of tissues

Answer 1

Epithelial, Connective, Muscle, and Nervous

Question 2

Connective Tissue

Answer 2

the most abundant and widely distributed tissue in the body

Question 3

What are the functions of connective tissue

Answer 3

structure, support, defense, transportation, and binding

Question 4

What are connective tissues scattered within

Answer 4

extracellular matrix

Question 5

What is an extracellular matrix

Answer 5

the material located between cells in the connective tissue, made up of ground substance and protein fibers

Question 6

Ground substance

Answer 6

the component of the extracellular matrix that surrounds the cells and protein fibers in the tissue

Question 7

What are the components of ground substance

Answer 7

Hyaluronic acid and chondroitin sulfate

Question 8

What are the 3 types of protein fibers

Answer 8

collagen, elastic, and reticular

Question 9

Collagen fibers

Answer 9

contain collagen protein, called white fibers, strong, and are often in collagen bundles

Question 10

Elastic fibers

Answer 10

Called yellow fibers, provide stretch, plentiful

Question 11

Reticular fibers

Answer 11

Forms a fine, branching network of collagen fibers, and gives support and strength to soft connective tissues

Question 12

Embryonic connective tissue

Answer 12

Mesenchyme, mucous connective tissue

Question 13

Mature connective tissue

Answer 13

Loose connective tissues, Dense connective tissues, cartilage, bone tissue, and liquid connective tissues

Question 14

Areolar connective tissue

Answer 14

one of the most widely distributed connective tissues in the body, contains several types of cells and all three protein fibers

Question 15

Fibroblasts

Answer 15

the most common cell type in areolar connective tissues

Question 16

Macrophages

Answer 16

Large white blood cells that engulf bacteria and cellular debris by phagocytosis

Question 17

Adipose tissue

Answer 17

contains adipocytes (store triglycerides)

Question 18

What are the 3 types of dense connective tissue

Answer 18

dense regular, dense irregular, and elastic

Question 19

Dense connective tissues

Answer 19

contain more protein fibers, there are fewer cells, fibroblasts are the predominant cell type

Question 20

Dense regular connective tissue

Answer 20

form strong attachment structures: tendons and most ligaments

Question 21

Dense irregular connective tissue

Answer 21

irregularly arranged in many directions, gives strength in tissues where pulling forces are exerted in many directions

Question 22

Elastic connective tissue

Answer 22

contains sheets of elastic fibers, allows stretching of structures

Question 23

Cartilage

Answer 23

a dense network of collagen or elastic fibers firmly embedded in a rubbery ground substance made of chondroitin sulfate (gives its resiliency)

Question 24

Chondrocytes

Answer 24

cartilage cells found in lacunae

Question 25

What are the 3 types of cartilage?

Answer 25

Hyaline, fibro, and elastic

Question 26

Hyaline cartilage

Answer 26

most abundant cartilage in the body, provides flexibility and support to structures, avascular

Question 27

Fibrocartilage

Answer 27

the strongest type of cartilage, found in high compression areas and resists compression

Question 28

Elastic cartilage

Answer 28

located within threadlike networks of elastic fibers,

Question 29

Blood tissue

Answer 29

fluid connective tissue with liquid extracellular matrix called blood plasma

Question 30

White blood cells

Answer 30

fight disease

Question 31

Red blood cells

Answer 31

carry oxygen

Question 32

Platelets

Answer 32

function in blood clotting

Question 33

Membranes

Answer 33

flat sheets of pliable tissues that cover or line a part of the body

Question 34

Epithelial membranes

Answer 34

a combination of an epitherlial layer and an underlying connective tissue layer

Question 35

Synovial membrane

Answer 35

lines joints and contains connective tissue but no epitherlium
