structural organisation in animals Flashcards
size range of cockroach
1/4 inches to 3 inchs(.6-7.6 cm)
length of periplaneta americana
34-53 mm long
length of oothecae
3/8’’ (8mm)
female cockroach produce —othecae with—— eggs
9-10 oothecae with 14-16 eggs
glandular epithe;liu,m are of 2 types whuch r they
unicellular consisting of isolated glandular cells (goblet cells of alimentary canal)
multicellular consisting of cluster of cells ( salivary glands)
compound epithelium covers
dry surface of skin
moist surface of buccal cavity,pharynx
inner lining of ducts of salivary glands
pancreatic ducts
in all connective tissues except blood the cells secrete
fibres of structural proteins called collagen or elastin😊
fibres provide -to tissue
strength elasticity flexibility
—–serve as a support framework for epithelium
areolar
areolar tissue contains
fibroblasts (cells that prod and secrete fibres)
macrophages
mast cells
dense connective tissue include
fibres and fibroblasts
dense irregular connctive tissue include
fibroblast and many fibres
main tissue that provide structural frame to the body
bones
