Question 1

Structure of Loose connective tissue

Answer 1

Relatively fewer cells and fibers than in dense connective tissue; fibers are loosely arranged

Question 2

3 types of loose connective tissue

Answer 2

Areolar, adipose, reticular

Question 3

Structure of areolar connective tissue

Answer 3

Fibroblasts; lesser amount of collagen and elastic fibers; viscous ground substance

Question 4

Structure of adipose connective tissue

Answer 4

Adipocytes

Question 5

Structure of reticular connective tissue

Answer 5

Mesh work of reticular fibers

Question 6

Function of areolar connective tissue

Answer 6

Packs around and binds organs

Question 7

Function of adipose connective tissue

Answer 7

Protects; stores fat; insulates

Question 8

Function of reticular connective tissue

Answer 8

Forms stroma of lymphatic organs

Question 9

Location of areolar connective tissue

Answer 9

Surrounding nerves, vessels; subcutaneous layer

Question 10

Location of adipose connective tissue

Answer 10

Subcutaneous layer; surrounding kidney and selected other organs

Question 11

Location of reticular connective tissue

Answer 11

Stroma of spleen, liver, lymph nodes; bone marrow

Question 12

Structure of dense connective tissue

Answer 12

High proportion of fibers to ground substance; protein densely packed together

Question 13

3 types of dense connective tissue?

Answer 13

Dense regular, dense irregular, elastic connective tissue

Question 14

Structure of dense regular connective tissue

Answer 14

Densely packed collagen fibers are parallel to direction of stress

Question 15

Structure of dense irregular connective tissue

Answer 15

Densely packed collagen fibers are interwoven; fibers are irregularly clumped together and project in all directions

Question 16

Structure of elastic connective tissue

Answer 16

Elastic and collagen fibers are arranged irregularly

Question 17

Function of dense regular connective tissue

Answer 17

Provides great strength and flexibility primarily in a single direction

Question 18

Location of dense regular connective tissue

Answer 18

Tendons and ligaments

Question 19

Function of dense irregular connective tissue

Answer 19

Provide tensile strength in all directions

Question 20

Location of dense irregular connective tissue

Answer 20

Dermis of skin; capsules of organs

Question 21

Function of elastic connective tissue

Answer 21

Provides framework and supports organs

Question 22

Location of elastic connective tissue

Answer 22

Walls of large arteries

Question 23

What are the 2 types of supporting connective tissue

Answer 23

Cartilage and bone

Question 24

3 major types of cartilage?

Answer 24

Hyaline, fibrocartilage, elastic cartilage

Question 25

Structure of hyaline cartilage

Answer 25

Glassy-appearing matrix; lacunae house chondrocytes; usually covered by perichondrium

Question 26

Function of hyaline cartilage

Answer 26

Smooth surfaces for movement at joints; model for bone growth; supports soft tissue

Question 27

Location of hyaline cartilage

Answer 27

Covers articular ends on long bones; most of fetal skeleton; costal cartilage; most of the larynx, trachea, nose

Question 28

Structure of fibrocartilage

Answer 28

Readily visible, parallel collagen fibers in matrix; lacunae house chondrocytes; no perichondrium

Question 29

Function of fibrocartilage

Answer 29

Resists compression; absorbs shock in some joints

Question 30

Location of fibrocartilage

Answer 30

Intervertebral discs; pubic symphysis; menisci of knee joints

Question 31

Structure of elastic cartilage

Answer 31

Contains abundant elastic fibers, elastic fibers for weblike mesh around lacunae; perichondrium present

Question 32

Function of elastic cartilage

Answer 32

Maintains structure and shape while permitting extensive flexibility

Question 33

Location of elastic cartilage

Answer 33

External ear; epiglottis of the larynx
