Flashcards in Tissues: Connective Deck (28):
1

Connective Tissues

never exposed to outside environment and don't have an apical surface

2

Functions

(a) enclosing and seperating structures
(b) connecting tissues
(c) support and movement
(d) storage of energy and minerals
(e) cushioning and insulation
(f) transporting (blood)
(g) protection (physical and immunity)

3

ALL connective tissues have

Specialized cells
Extracellular matrix (protein fibers and ground substance)

4

Connective cell matrix

makes up most of the volume of connective tissue (matrix often determines function)

5

Collagen

most abundant fiber in body

6

PREFIX
(a) Blast
(b) Cyte
(c) Break down matrix

(A) make matrix
(B) maintain matrix
(C) break down matrix

7

Connective Tissue Classification

Proper Connective Tissue
Supporting Connective Tissue
Fluid Connective TIssue

8

Proper Connective (divided by ground to fiber substance)

Loose:
(fewer fibers, more ground)
- adipose, areolar, rticular
Dense:
(more fibers, less ground)
- regular irregular

9

Supporting Connective

supports soft tissues and weight of body
Cartilage:
gel type ground substance with various fibers for shock and absorption/ protection
Bone: calcified for weight support

10

Fluid Connective

Blood:
blood cells in a fluid matrix...fibers are dissolved proteins... drop out of solution when blood clots

11

Hyaline Cartiladge (supporting)

Lacuna- contains cells
Chondrocyte- the cell itself
(looks like oysters) Pg. 80 LAB (nose, ribs chk bone white stuff)

12

Fibrocartilage (supporting)

matrix less firm than hyaline (vertebrae, discs of knee joint, pubic symphesis)
-looks like the galaxy

13

Elastic cartiladge (supporting)

-

14

Bone cartiladge (supporting)

Lacuna- black dota

15

Dense Regular Tissue (proper)

dense with fibers (attaches muscles to bones: ligament tendon and shoulder joint)

16

Dense Irregular Tissue (proper)

irregularly arranged (wavy but disorder)
-able to withstand tension exerted in all directions
Ex: fibrous joint capsule

17

Blood TIssue (fluid)

RBS & WBC & Platelets in a fluid matrix (plasma)
-plasma is the Extracellular Matrix
-transport of respiratory gases, nutrients, wastes
-55% plasma
-45% formed elements = specialized cells
(erythrocyte, leukocyte, platelets,

18

Adipose Tissue (loose proper)

closely packed, fat cells, nucleus pushed to side by fat.
-provides reserve fuel, insulates, and protects organs. (under skin, around kidneys, in breasts)

19

Areolar Tissue (loose proper)

wraps and cushions organs (forms mucous membranes)

20

Reticular Tissue (loose proper)

made of reticular fibers
-dark staining network forming internal skeleton of spleen

21

Elastic Cartiladge (supporting)

dense elastic fibers (oysters and pasta)
-allows recoil of stretching (walls of arteries and ear)

22

Fibroblast

CTP; working cells that make and secrete matrix

23

Fibrocytes

mature cells; secrete matrix to maintain tissue

24

Macrophages

large, cells of immune system that eat pathogens and damaged cells

25

Adipocytes

fat cells (store energy in trigylcerides)

26

Mesenchymal cells

stem cells that respond to injury or infection that break into Fibroblast, Macrophages, or others

27

Mealnocytes

sysnthesize and store the pigment melanin (epidermis)

28

Mast cells

release histamine to stimulate inflammation after injury or infection
