Flashcards in Structural Organisation In Animals( Animal Tissue ) Deck (49):
1

Who introduced the term epithelium

Ruysch

2

What is the basal lamina composed of

Mucopolysaccharides and glycoproteins, but decreased by epithelial tissue.

3

What is the fibrous or reticular lamina composed of

Collagen or recticular fibres of the underlying connective tissue.

4

What is the function of simple epithelium tissue

As lining for body cavities, ducts and tubes

5

Squamous epithelium is also known as

Pavement epithelium

6

Where are the simple squamous tissue located

In the walls of blood vessels
Air sacs or alveoli
Lymph vessels
Wall of bowman's capsule
Loop of Henri of nephron,
Coelomic cavities etc

7

What are the functions done by simple squamous tissue

Filtration in bowman's capsule
Exchange of materials between blood capillaries and tissue fluid

8

What is the use of microvilli as brush in tissues

It increases the surface area to several times

9

Where is cuboidal squamous tissue located

Tubular parts of nephron
Ducts of glands
Thyroid follicles
Ovaries and testes( germinal epithelium)

10

Where is brush bordered cuboidal epithelium present

On the proximal convoluted tubule (PCT)of nephron in kidney.

11

Functions of cuboidal epithelium

Reabsorbtion and secretion

12

Where is the nuclei of columnar epithelium situvated

It is near the base of the cells

13

The cells which produces mucus in columnar tissue

Goblet tissue

14

The epithelium containing mucus secreting cells, along with underlying supporting connective tissue is called

Mucosa ,or Mucous membrane

15

Compound epithelium is also known as

Stratified epithelium

16

Compound epithelium is classified into

Keratinised and non keratinised squamous tissue

17

Speciality of keratin

It is water proof

18

Where is keratinised squamous tissue is located

Dry surfaces

19

Where is non keratinised squamous tissue located

Wet surfaces like mouth , buccal cavity, cheek epithelium etc

20

The transitional epithelium is resting

Fluid matrix

21

Speciality of plastic epithelium

Stretchable

22

Where is the transitional epithelium located

Renal pelvis , ureter , urinary bladder etc..

23

Gap junction is also known as

Communication junction

24

Function of gap junction

Allows transport of materials between cells

25

Function of the interdigitated cell junction

Attach adjacent cells together

26

Function of tight junction

Check the leakage of cytoplasm

27

Function of adhering junction

Adherence of two cells with the help of cementing substances

28

Example of adhering junction

Protein plaque

29

Classification of adhering junction

Zonula adherence
Macula adherence
Hemi desmosome

30

In hemi desmosome the plaque is located

At the base of the cell

31

A cell/tissue / organ with secretary function is known as

A gland

32

Type of cells in glandular epithelium

Cuboidal or columnar cells

33

Example for unicellular gland

Goblet/ chalice/ mucocyte ,secrete mucus

34

A multicellular gland

Salivary gland , sebaceous gland , sweat gland etc.

35

Some heterocrine glands

Pancreas , gonads (ovary/testes)

36

The most abundant connective tissue in our body

Areolar tissue

37

Dense regular connective tissue

Tendons and ligaments

38

Dense irregular connective tissue

Dermal skin

39

Colour of collagen fibres

40

Elastin fibre colour

Yellow fibre

41

Connective tissue whose matrix is solid

Bone and cartilage

42

Fluid connective tissue

13 species

45

Name any common species of earth worm
