Connective Tissue 2

Question 1

3 types of connective tissue

Answer 1

connective tissue proper (loose and dense
specialized (cartilage and bone)
embryonic (mesenchyme and mucous)

Question 2

2 main types of embryonic connective tissue

Answer 2

1) mesenchyme.

2) mucous CT

Question 3

mesenchyme embryonic CT is derived from ____. Composition?

Answer 3

derived from MESODERM. Mainly cells, no fibers. irregularly shaped cells that may be connected by CYTOPLASMIC PROCESSES

Question 4

mucous embryonic CT is found in the __ ___. composition?

Answer 4

found in the umbilicle cord. Few cells, lots of ground substance and collagen fibers.

Question 5

areolar tissue includes what types of cells? what kind of fibers are present in this tissue? where can you find this CT?

Answer 5

Loose Aereolar CT has many types of cells (mast cells, macrophages etc.) but most prevolent is fibroblasts.

• has both collagen and elastin fibers

found in :upper dermis, mesenteries, around blood vessels and muscles.

Question 6

purpose of reticular connective tissue? where would you find this?

Answer 6

reticular connective tissue is reich in reticular fibers made of reticulin.

forms the framework or many HEMOPOEITC organs (liver, spleen, lymph nodes)

Question 7

Yellow/white adipose CT is __locular, which means:

Answer 7

unilocular: one huge fat droplet that pushes all organelles and nuceli to edge of cell membrane.

Question 8

function of white adipose CT

Answer 8

METABOLISM REGULATION, energy reserve (adipocytes store triglycerides), insulation, and protection

Question 9

location of white adipose CT

Answer 9

subcutaneous layer of skin, may act as visceral fat, around some organs (structural fat).

ALSO IN MEDULLARY CAVITY OF LONG BONES and in MAMMARY GLANDS.

Question 10

how does white adipose CT facilitate metabolism regulation?

Answer 10

it produces LEPTIN that influences aptude. (decreases appetite) therefore, because white adipose CT produces hormones, it is an ENDOCRINE ORGAN.

Question 11

brown adipose CT is ___locular. Why is it called brown adipose? Function?

Answer 11

MULTILOCULAR; multiple fat droplets. Organelles and nuclei may or may not be pushed around the edges or trapped between fat droplets in the middle of the cell.

brown in color because a lot of mitochondria and highly vascular

function: thermoregulation

Question 12

3 types of dense CT

Answer 12

1) dense regular
2) dense irregular
3) dense regular ELASTIC

Question 13

Composition of dense REGULAR CT? What structures does dense regular CT form?

Answer 13

Composed of parallel bundles of collagen 1 fibers. Very strong. Makes tedons and ligaments.

Question 14

Composition of dense IRREGULAR CT? What structure does it form?

Answer 14

randomly oriented bundles of collagen type 1. Forms the deep dermis of skin, organ capsules, fasciae, periosteum and perichondrium.

Question 15

composition of dense regular elastic CT? wwhere is this found?

Answer 15

made of parallel elastic fibers. found in VOCAL CORDS

Question 16

specialized CT function

Answer 16

for SUPPORT. not necessaily binding and connecting organs.

Question 17

2 types of specialized CT

Answer 17

1) cartilage (flexible support)

2) bone

Question 18

T/F cartilage is avascular

Answer 18

true.. it gets its nutrients from perichondrium.

Question 19

main fiber in cartlage

Answer 19

collagen. can’t usually see it. Elastic cartilage also has elastic fibers

Question 20

hyaline cartilage contains ___ ___ which allows it to be highly hydrated

Answer 20

hyaluronic acid, allows for cross linking of type 2 collagen and proteoglycan. highly hydrated = strong

Question 21

3 types of cartilage

Answer 21

1) hyaline
2) elastic
3) fibro

Question 22

what type of fiber is associated with hyaline cartilage? where can you find hyaline cartialge?

Answer 22

collagen 2

found in fetal skeleton, trachea rings, larynx, nasal septum, articular surfaces ofbones but with no perichondrium

Question 23

function of elastic cartilage. Location?

Answer 23

function: provide support but a bit more flexible.
location: epiglottis, eustacian tube, ear.

Question 24

location of fibrocartilage. characterized by alternating layers of ____ ___ and ___ ____ CT.

Answer 24

Pubic symphisys, intervertebral discs, where ligaments insert into bone. characterized by alternating layers of HYALINE CARTILAGE and DENSE REGULAR CT.

Question 25

T/F: Fibrocartilage has a perichondrium

Answer 25

false.
