NAME THE PHYLA THAT CONTAINS ONLY MARINE MEMBERS?
CTENOPHORA, ECHINODERMATA, HEMICHORDATA.
WHICH OF THE FOLLOWING GIVEN TAXON HAS FRESHWATER AS WELL AS MARINE MEMBERS?
(a) HEMICHORDATA
(b) CTENOPHORA
(c) CNIDERIA
(d) ECHINODERMATA
(c) CNIDERIA
WHAT IS MATRIX IN TISSUE?
INTERCELLULAR CONTENT DISCHARGED BY THE SAME CELL, EXCEPT FLUID CONNECTIVE TISSUE.
Who coined the term tissue?
Bischat
What is a tissue?
The tissue can be defined as a group of cells having similar structure, function as well as origin.
The matrix of a tissue is living in nature. True or false.
False the matrix of a tissue is non living in nature.
What is the function of a matrix in the tissue.
It acts as exchange medium for the Cell of tissue.
All type of tissue have the same chemical composition and amount of matrix. true or false.
False, chemical composition and amount of matrix is variable.
Are all ECF (extra cellular fluid) matrix.
No e c f is not always matrix rather than it may be tissue fluid.
Tissue grade level organisation’s for the first time appeared in which of the following phylum?
A. Porifera
B. Arthropods
C. Cnideria
D. Annelida
C. Cnideria
Division of labour’s started in which phylum?
Cnideria
What is the another name of epithelial tissue?Also state the origin of epithelial tissue.
Covering and lining tissue.
Origin: ectodermal, mesodermal, endodermal.
What is the another name of connective tissue?Also estate the origin of connective tissue.
The another name of connective tissue is connecting and supporting tissue.
Origin is misodermal.
What is the another name of muscular tissue?Also state the origin of muscular tissue.
The another name of muscle tissue is contractial tissue.
Mostly mesodermal EXCEPT, IRIS AND CILLIARY MUSCLE. THEY ARE ECTODERMAL.
What is the another name of neural tissue?Also a state it’s origin.
Conducting and responding tissue.
Mostly ectodermal EXCEPT MICROGLIOCYTE. IT IS MESODERMAL.
What is epithelial tissue?
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.
How are cells arranged in epithelial tissue?
Cells remain compactly arranged.
Tissue matrix is present in epithelial tissue, true or false?
False matrix is either little or absent in epithelial tissue.
Which epithelial tissue does not rest on a basement membrane?
Transitional epithelial.
Basement membrane is non cellular, true or false.
True, basement membrane is non cellular or acellular.
What is basement membrane formed by?
Basement membrane is formed by same epithelial and underlying tissue.
Same epithelial- Basel lamina (mucopolysacride, glycoprotien)
Underlying tissue- fibrous lamina (protein)
What is the function of basement membrane?
It allows the movement of material between epithelium and underlying tissue.
What are the different types of junctions through which epithelial cells remain connected?
A. Tight junction- prevents the leaking of material across the cell membrane.
B. Gap junction
C. Adhering junction- provides Anchorage function.
What is gap Junction?
It allows the movement of materials like ions, small molecules and sometimes big molecules between adjacent cell.
Which of the following is uncommon to epithelial:
A. Cells
B. Metabolism
C. Capillary
D. Growth
C. Capillary because epithelial doesn’t contain blood vessels EXCEPT INNER EAR EPITHELIAL.
In which type of epithelial tissue cells are arranged in one layer?
Simple epithelial
What is the location of simple epithelial tissue?
In the coelom (body cavity) and places where diffusion, filtration, friction, absorption, etc. occur.
