Answer 1

connective tissue

Question 2

what are the functions of connective tissue(4)

Answer 2

support and strengthens other tissues
protects and insulates internal organs
separates structures (eg. m. in groups of m.)
main source of immune response

Question 3

what is the area of energy reserve storage for connective tissue

Answer 3

adipose tissue

Question 4

t/f connective tissue is highly vascular without any exceptions

Answer 4

false except for cartilage which is avascular

Question 5

what is blood used for in connective tissues

Answer 5

transport sys

Question 6

is connective tissue similar to epi tissue concerning its organization

Answer 6

no it contains large amounts of extracellular material in which are found single cells or groups of cells

Question 7

what consists extracellular matrix

Answer 7

protein fibers and ground substance

Question 8

what determines a tissue’s quality

Answer 8

the structure of the extracellular matrix

Question 9

amount of ground substance found btw the cells and fibers in connective tissue can be

Answer 9

fluid (loose), semifluid(loose), gelatinous(loose)
and calcified (dense)

Question 10

what is the function of ground substance (4)

Answer 10

support cells, binds them together, stores water, provides a medium of exchange btw blood and cells

Question 11

what are the 2 most common cells associated w connective tissue

Answer 11

fibroblasts and macrophages (phagocytes)

Question 12

what are fibroblasts (look, form what, and found where)

Answer 12

-large, flat cells w branching processes
-form the fiber for strength and structure (mature cells=fibrocytes)
-found in all general connective tissue, most numerous

Question 13

what are macrophages (function)

Answer 13

move thru matrix and engulf waste products or dead cells, can be fixed or wandering

Question 14

what does blast mean

Answer 14

younger, builder and immature cell

Question 15

do the macrophages and fibroblast have to work in sync

Answer 15

yes

Question 16

what are the 3 types of fiber (fibrillar extracellular matrix found in the ground substance btw the cells) in connective tissue

Answer 16

collagenous (white)
elastic (yellow)
reticular (neutral)

Question 17

what is collagenous fiber in connective tissue (whats it made from, form found has, strong?, function)

Answer 17

made from protein collagen
usually found in // bundles
strong like steel cable (resists to tensile forces like stretching or pulling), non-elastic but not stiff
supportive function

Question 18

what is the most abundant protein in the body

Answer 18

collagen

Question 19

what is elastic fiber in connective tissue (form found in, made from what, strong?, can be stretched?)

Answer 19

long cylindrical ribbon structure
made from protein elastin
strong but has an elastic quality (rubberband)
can be stretched 150% but returns to og length

Question 20

what is elastic fiber abundantly found in

Answer 20

skin, arterial walls, lung tissue and also found in bones

Question 21

what is reticular fiber in connective tissue (referred as?, arranged how?, function, what does it bind to)

Answer 21

referred to as immature collagen
arranged in fine bundles (cobweb)
provide support in the walls of blood vessels
help form the basement mem
binds to smooth m. in organs

Question 22

what forms the framework of organs or glands to which epi cells attach and that is non-elastic, like collagen

Answer 22

reticular fiber

Question 23

what are the 3 loose connective tissues

Answer 23

areolar ct
adipose tissue
reticular ct

Question 24

what is areolar ct (where and the function)

Answer 24

ct layer that connects skin to underlying tissues, surrounds blood vessels, n. and organs
provides strength, elasticity and support

Question 25

what is adipose tissue (where, funtion, subtypes)

Answer 25

found where fat is stored
protective and insulation functions (reduces heat loss)
essential and non-essential fats

Question 26

what is reticular ct

Answer 26

supporting framework of liver, spleen, lymph nodes, red bone marrow, blood vessels and m.

Question 27

whats the main difference btw loose ct and dense ct

Answer 27

same elements but dense ct has much more collagen

Question 28

what are the 3 classifications of dense ct

Answer 28

dense regular ct
dense irregular ct
elastic ct

Question 29

what type of dense ct is laid down in a regular fashion,, xtracellular matrix looks shiny and white, is strong tissue and forms tendons, aponeuroses and ligs

Answer 29

dense regular ct

Question 30

why are ligaments and tendons slower to heal ythan m.

Answer 30

because they have fewer blood ve3ssels

Question 31

what type of dense ct provides a strong attachment btw structures

Answer 31

dense regular ct

Question 32

what type of dense ct is collagenous fibers and fibroblasts interwoved and irregularly arranged

Answer 32

dens irregular ct

Question 33

what type of dense ct is often foudn in sheats and forms the m. fascia, found in periosteum and perichondrium

Answer 33

dens irregular ct

Question 34

what type of dense ct in found in joint capsules, in the dermis of skin and is leather like

Answer 34

dense irregular ct

Question 35

what type of dense ct consists of elastic fibers and fibroblasts and appears yellowish in color

Answer 35

dense elastic ct

Question 36

what type of dense ct is found in lung tissue, wall of elastic a. , trachea, vocal cords, some ligamenrts, bronchioles (allows stretching of various o0rgans)
