Cnideria

Question 15

What is the another name of epithelial tissue?Also state the origin of epithelial tissue.

Answer 15

Covering and lining tissue.
Origin: ectodermal, mesodermal, endodermal.

Question 16

What is the another name of connective tissue?Also estate the origin of connective tissue.

Answer 16

The another name of connective tissue is connecting and supporting tissue.
Origin is misodermal.

Question 17

What is the another name of muscular tissue?Also state the origin of muscular tissue.

Answer 17

The another name of muscle tissue is contractial tissue.
Mostly mesodermal EXCEPT, IRIS AND CILLIARY MUSCLE. THEY ARE ECTODERMAL.

Question 18

What is the another name of neural tissue?Also a state it’s origin.

Answer 18

Conducting and responding tissue.
Mostly ectodermal EXCEPT MICROGLIOCYTE. IT IS MESODERMAL.

Question 19

What is epithelial tissue?

Answer 19

Epi- upon
Thelio- to grow.
This tissue appears as body covering in the lining of body cavity and places inside body wear absorption, diffusion, filtration, friction as well as well as secretion occurs.

Question 20

How are cells arranged in epithelial tissue?

Answer 20

Cells remain compactly arranged.

Question 21

Tissue matrix is present in epithelial tissue, true or false?

Answer 21

False matrix is either little or absent in epithelial tissue.

Question 22

Which epithelial tissue does not rest on a basement membrane?

Answer 22

Transitional epithelial.

Question 23

Basement membrane is non cellular, true or false.

Answer 23

True, basement membrane is non cellular or acellular.

Question 24

What is basement membrane formed by?

Answer 24

Basement membrane is formed by same epithelial and underlying tissue.
Same epithelial- Basel lamina (mucopolysacride, glycoprotien)

Underlying tissue- fibrous lamina (protein)

Question 25

What is the function of basement membrane?

Answer 25

It allows the movement of material between epithelium and underlying tissue.

Question 26

What are the different types of junctions through which epithelial cells remain connected?

Answer 26

A. Tight junction- prevents the leaking of material across the cell membrane. B. Gap junction C. Adhering junction- provides Anchorage function.

Question 27

What is gap Junction?

Answer 27

It allows the movement of materials like ions, small molecules and sometimes big molecules between adjacent cell.

Question 28

Which of the following is uncommon to epithelial: A. Cells B. Metabolism C. Capillary D. Growth

Answer 28

C. Capillary because epithelial doesn't contain blood vessels EXCEPT INNER EAR EPITHELIAL.

Question 29

Answer 29

Simple epithelial

Question 30

What is the location of simple epithelial tissue?

Answer 30

In the coelom (body cavity) and places where diffusion, filtration, friction, absorption, etc. occur.
