Q

difference between the plaque in desmoeses and the plaque ni adhern

A

in desmoses the plaque is attached to intermediate filaments (keratin)

in adherns cell junction the plaque is attached to microfilaments

2) Reticular Lamina (made by connective tissue

17

basement membrane that has proteins as collagen produced by fibroblasts

A

Reticular Lamina

18
Q

epithelial tissues are classified according to layers according to

A

Simple
Pseudostratified
Stratified

19
Q

epithelial tissues are classified according to shape as

A

squamos
cuboidal
coloumnar
transitional

20
Q

Location of Simple Squamous epithelial tissues

A

1) Endothelium that lines the cardiovascular and lymphatic system
2) Mesothelium that forms the epithelial layer of serous membrane
3) In airsacs of lungs, bowman’s capsule of kidneys and inner surface of lympanic membrane ( eardrum )

21
Q

Function of simple squamous tissue

A

Filtration (in kidney)
diffusion (oxygen into blood vessels of lungs)
secretion ( in serous membrane )

22
Q

single layer of flat cells that looks like tiled floor when viewed from apical surface

A

Simple Squamous tissue

23
Q

Single layer of cube shaped cells, with centrally located nucleus

A

Simple cuboidal epithelial tissue

24
Q

Location of Simple cuboidal epithelial tissue

A

Surface of ovary
Surface of capsule of lense of the eye
lines kidney tubules
posterior surface of retina of eye
thryoid gladns and some ducts in the pancreas

25
Q

Function of simple cuboidal tissue

A

secretion and absorbtion

26
Q

single layer of column like cells
the nuclei is oval near the base of the cell containing epithelial cells iwth microvilli at the apical surface and goblet cells

A

simple Non ciliated columnar

27
Q

Location of simple Non ciliated columnar

A

Lines gastrointestinal tract
lines ducts of many glands and gallbladder

28
Q

function of simple Non ciliated columnar

A

Secretion and absorbtion

secretion lubricates linings of digestive, respiratory and reproductive tracts and most of the urinary tract

help in keeping the lining of the stomach safe from the acidic gastric juice

29
Q

single layer of cilated column like cells with oval nuclei near base of cells with goblet cells scattered

A

Simple cilated columnar tissues

30
Q

Location of Simple cilated columnar tissues

A

lines bronchioles of the respiratory tract
fellopin tubes
uterus
paranasal sinuses
central canal of spinal cord
ventricles of brain

31
Q

functions of Simple cilated columnar tissues

A

1) the cilia moves mucus and foriegn particles towards throat where they can be coughed out
2) cilia also helps in moving oocytes from ovaries through fallopian tubes to the uterus
