What are the 4 primary tissues?

Epithelial, connective, muscle and nerve tissue.

1

What type of tissue is used for covering or lining?

Epithelial tissue

2

Define epithelial tissue.

Tissue that is used for covering and line; secreting tissue

3

Define connective tissue.

Tissue that bind things together; fills in space.

4

What type of tissue binds things together, or fills in space.

Connective tissue

5

What tissue shortens to produce movement?

Muscle tissue

6

Define muscle tissue.

Tissue that shortens to product movement.

7

Which tissue conducts impulses?

Nerve tissue

8

Define nerve tissue

Tissue that conducts impulses

9

The lung tissue that gases pass through to enter the blood is composed of what?

Simple squamous epithelial tissue

10

Which of the following is composed of dense regular connective tissue.

The achellis tendon, because we want it to be strong

11

Which of the following is true about the serous membrane

The serous membrane that cover the lung is called pleura.

12

Where does mitosis happen most rapidly?

Epithelial tissue

13

Which tissues do not undergo mitosis typically.

Muscle and nervous

14

In which tissue does the rate of mitosis vary?

Connective tissue

15

What are the functions of epithelial tissue?( not all do all function it varies)

Synthesizes structures, secretes substances, absorbed substances, and --------- underlying structures.

16

List 4 characteristics of epithelial tissue.

Cells are packed tightly, one apical surface and one basal surface attached to the basement membrane, cells reproduce rapidly, and not vascular.

17

How can you classify epithelial tissue.

By number of layers ( simple, stratified, suedostratified)
By shape ( squamous, cuboidal, columnar)
By whether it is ciliated or not

18

Define transitional epithelial.

Apical cells change shape, lines organs thy stretch

19

How would you classify the function of epithelial tissue?

Covering, lining and glandular

20

What is glandular epithelial tissue composed of?

Composes parenchyma of glands (the functional component)
Also secretes compounds

21

Parenchyma

Functional component of glands

22

Stroma

The matrix or supporting tissue of an organ

23

What are the two classifications of glands

Endocrine (entering)
Exocrine (exiting)

24

Endocrine glands

Secrete hormones directly into the body or body fluid
For the most part the are simple cuboidal

25

Exocrine gland

Excrete to an external surface or into a cavity that leads to the outside of the body

26

Examples of exocrine glands

Sweat glands
Lacrimal glands

27

Examples of exocrine glands that secrete onto internal surfaces

Salivary glands
Mucus glands
Pancreas

28

Characteristic of connective tissue

Separated by a matrix (consisting of fibres and ground substance between cells
Structures vary greatly

29

Fibroblasts

Fibres and ground substance; makes up the matrix

30

Macrophages

Engulf substances

31

Plasma cells

Produce antibodies

32

Mast cells

Produce histamine (cause an inflammatory reaction)

33

Adipocytes

Fat cells

34

What is ground substance composed of

Hyaluronic acid (the glue)
Chondroitin sulfate, dermatan sulfate, keratin sulfate
Fibronectin

35

What 5 main cells are found in connective tissue

Fibroblasts
Macrophages
Plasma cells
Mast cells
Adipocytes

36

What is hyaluronic acid?

A viscous substance that facilitates movement of phagocytes and has protective qualities.
Broken down by hyaluronaise

37

Which of the three main substances in ground substance supports cartilage, bone, skin, blood vessels and atrial valves.
1. Hyaluronic acid
2. Fibronectin
3. Chondroitin sulfate, dermatan sulfate, keratan sulfate

3. Dermatan sulfate, Chondroitin sulfate, keratan sulfate

38

Fibronectin (adhesive protein)

Links components of ground substance together

39

What is the general function of connective tissue

Support
Protect
Storage
Repair

40

Name 3 types of fibres

Elastic (made of elastin; stretch)
Collagen (strong, resistant fibres with some flexion)
Reticular(form stroma)

41

Stroma

The matrix supporting tissue of organs

42

Name 5 types of mature connective tissue

Loose connective tissue
Dense connective tissue
Cartilage
Bone tissue
Blood

43

Name three types of loose connective tissue

Areolar
Adipose
Reticular

44

Name three types of dense connective tissue

Regular
Irregular
Elastic

45

Name three types if cartilage

Hyaline cartilage
Fibrocartilage
Elastic cartilage

46

Chondrocytes
