structural organisation in animals Flashcards
epithelial tissue fn
covering or lining for some part of the body
fn of simple epithelium
lining for body cavities ,ducts,glands
fn of simple epithelium
lining for body cavities ,ducts,and tubes
on the basis of ———–simple epithelium divided into 3 types
structural modification of cells
squamous epitheliumm found in
walls of blood vessels
air sacs of lungs
cuboidal tissues found in
ducts of gland
tubular parts of nephrons in kidneys
brush bordered cubuoidal epiythelium found in
PCT
columnar epitheliaum found in
lining of stomach and intestine
brush bordered cub epithelium
intestinal villi
ciliated epithelium found in
inner surface of hollow organs like bronchioles and fallopian tubes
cub and columnr ep tissue function
secretion and absoprtion
unicellular glandular epithelium eg
mucus gland
goblet cells
multicellular glandular epi eg
salivary gland
sweat gland
compound epithlium function
cover the dry surface of skin
moist surface of buccal cavity,pharynx
inner lining of ducts of salivary glands
and of pancreatic duct (DSPBSP)
code ; DR SPB SPL
in nearly all animal tissues ———-provide both structural and functional links between its individual cells
specialised junctions
—–helps to stop sub leaking across a tissue
tight jns
functions of neuroglial cells
protect and support neurons
smooth muscles are seen in
blood vessels
stomach
intestine
in all connective tissue except bllod the cell secrete fibres of structural proties called
collagen or elastin
the fibres peovide
strength elasticity flexibility to the tissue
the cells also secrete —–which accumulate between cells and fibres and act as matrix
modified polysaccharides
areolar tissue containms
fibroblasts
macrophages
mast cells
dense connective tissue includes
fibres ,fibroblasts
dense irregular includes
fibroblasts and many fibres mainly collagen
tensons connects
muscle to msucle
