1

All connective tissue derives from __

mesenchymal cells

2

Connective Tissue consists of __ and ___

- prominent ECM consisting of ground substance and 3 types of protein fibers

3

Connective tissue has 3 protein fibers which include:

collagen fibers, elastic fibers, reticular fibers

4

4 general types of connective tissue:

1. connective tissue proper
2. cartilage
3. Bone
4. Blood

5

Connective Tissue Proper is made up of

scattered cells called fibroblasts

6

What do Fibroblasts do?

secrete an extensive ECM filled with many types of protein fibers

7

Is connective Tissue Proper vascularized of avascularized

vascularized

8

1. connective tissue proper

1. most widely distributed class of tissue in body. contains fibroblasts]

9

2. Cartilage

-flexible but resist tension, twisting and compression forces

10

(connective tissue Proper) loose (areolar)

2. loose appearance
-has all collagen fiber in ground substances
-fibroblast nuclei

11

(connective tissue Proper) Reticular

3. reticular fibers produced by reticular cells. (spleen and lmyph nodes)

12

(connective tissue Proper) adipose

4. fat tissue made up of adipocytes, very little ECM , (around skin and lining organs

13

(connective tissue Proper) dense regular cartilaginous are ___ and are found __ (2)

5. collagen fibers arranged in one direction, very strong structure (tendons and ligaments)

14

(connective tissue Proper) dense irregular cartilaginous are ___ and are found __ (3)

6. collagen fibers arranged in many directions, also strong, (dermis , joints and skin)

15

(connective tissue Proper) dense elastic

7. elastic fibers (lines large BV's and certain ligaments

16

connective tissue functions

bindings and supporting tissue for all other tissues in body

17

Muscle Tissue Function

Adapted to contract

18

Cartilage cells consist of ___

Chondrocytes

19

Chondrocytes are in cavities called

Lacunae

20

The 3 types of Cartilage

Hyaline, Fibro Cartilage, Elastic

21

Is Cartilage vascular or avascular?

avascular

22

Hyaline Cartilage

-lacks protein fibers so gives a smooth glossy appearance
-provides frictionless surface for bones to articulate

23

Hyaline Cartilage is found ___ (4)

ears, nose, trachea, respiratory tract

24

Fibrocartilage

-a lot of fibers (collagen fibers
-

25

Fibrocartilage functions for

shock absorbance

26

Synovial joints which reduces friction are made up of

Articular Hyaline Cartilage

27

Elastic Cartilage is __ and found in ___

visible fibers that stretch and recoil; ear

28

Bone is ___

tissue containing osteocytes in ECM that consist of calcium and collagen fibers

29

Bones is arranged in layers called

Lamellae

30

Blood

consists of cells called erythrocytes and leukocyctes
and plasma in an ECM
