connective tissue proper

Question 1

connective tissue

Answer 1

-fills internal spaces
- provide structural support
- stores energy

Question 2

connective tissue components

Answer 2

• specialized cells (creating or maintaining material)
• extracellular protein fibers
• fluid called ground substance

Question 3

matrix

Answer 3

extracellular fibers and ground substance
- most volume of connective tissue is matrix, not cells

Question 4

connective tissue proper

Answer 4

has matrix of fibers (loose and dense fibers) in a maple syrup-like ground substance

Question 5

fluid connective tissue

Answer 5

matrix of cells and proteins in a liquid ground substance (blood and lymph)

Question 6

supporting connective tissue

Answer 6

matrix of proteins fibers in a gel or a sold ground substance

cartilage and bone

Question 7

mesenchyme

Answer 7

mesoderm forms the mesenchyme (first connective tissues)
- consists of mesenchymal stem cells and a matrix of viscous fluid with few protein fibers

Question 8

origins

Answer 8

mesenchyme begins to lay down fibers and ground substance, fibers become denser and the MSC’s differentiate into other cell types

Question 9

fibroblasts

Answer 9

create all connective tissue

fibrocytes - maintain tissue

Question 10

fibers of connective tissue

Answer 10

collagen fibers
elastic fibers
reticular fibers

Question 11

collagen fibers

Answer 11

thickest of fibers, somewhat flexible and the strongest
- give ligaments and tendons their resilience and strength

tensile strength

Question 12

elastic fibers

Answer 12

thinner than collagen, stretch easily, branch and rejoin
- allows structures such as blood vessels to stretch and relax

Question 13

reticular fibers

Answer 13

thinner than collagen fibers, forms a branching woven network
- found in organ with abundant space such as liver, lymph nodes, and spleen (stabilize and supports)

tough but flexible, resist forces appled from many directions

Question 14

elastic fibers

Answer 14

thinner than collagen, stretch easily, branch and rejoin, wavy (recoil)

Question 15

loose connective tissue

Answer 15

areolar tissue
adipose tissue
reticular tissue

Question 16

areolar tissue

Answer 16

found surrounding blood vessels, nerve bundles, muscle, and organs

cushions organs, provides support but permits movement, defense against pathogens

Question 17

adipose tissue

Answer 17

found under the skin, around the heart, and padding around the joints

padding and cushions shock, insulates, stores energy

Question 18

reticular tissue

Answer 18

found in the kidney, lymph nodes and spleen

provides supporting framework

Question 19

areolar tissue

Answer 19

cushions organs, provides support but permits movement, all cells of connective tissue proper found here,
in the skin, respiratory, urinary tracts, between muscles, around blood vessels nerves and joints
have macrophages, mast cells, fibrocytes,

Question 20

adipose tissue

Answer 20

deep to skin, sides, buttocks and breast, padding around eyes and kidney, provides padding and cushions shocks, insulates heat and stores energy
- composed of only adipocytes

Question 21

reticular tissue

Answer 21

liver, kidney, spleen, lymph nodes and bone marrow; provides supporting mesh framework

Question 22

dense connective tissue

Answer 22

dense regular
dense irregular
dense elastic

Question 23

dense regular

Answer 23

collagen fibers packed tightly, no stretch, found in ligaments and tendons

provides firm attachment, stabilizes bones

Question 24

dense irregular

Answer 24

throughout entire body, bundles of collagen running in all directions. found covering blood vessels, dermis of skin, sheath around periosteum and periochondria, duct tape of body

provides strength to resist forces in many directions

Question 25

dense elastic

Answer 25

has stretch and recoil properties, found inanely two places, walls of the aorta and the ligaments flavum (spine) (between vertebrae of spine)

springey and resilient, expansion and contraction

Question 26

dense regular

Answer 26

tendons, ligaments, covering skeletal muscles
- densely packed parallel bundles of collagen fibers
- provides attachment and reduces friction between muscles, withstands great tension, stabilizes, a few elastic fibers, fibroblasts

Question 27

dense irregular

Answer 27

irregularly arranged collagen fibers, some elastic fibers, fibroblasts
- able to withstand tension in many directions, helps prevent over expansion of organs, in capsules of visceral organs, in the skin and periosteum of bone

Question 28

dense elastic

Answer 28

walls of the aorta and the ligaments flavum (spine)
- stabilizes position of vertebrae and permits expansion and contraction of organs
-
