what is the role of nervous tissue
control and coordinate body activity
what is nervous tissue made of
nerve cells
what is the function of epithelial tissue
protect skin
absorption in digestive tract
secretion of sweat and saliva
what is the structure of epithelial cells
cells packed close together
lines the body and organs
what are the 2 classifications of arrangement of cells
simple
stratified
what are the 3 classifications of shape of cells
squamos
cuboidal
columnar
what is transitional epithelium
multiple layers that can expand and contract
give an example of an organ made of transitional epithelium
bladder
how is glandular tissue formed
epithelial secretions increase causing cells to cluster and sink producing a gland
what are the 2 types of glands
exocrine and endocrine
describe exocrine glands
connect to epithelium surface and pass secretions by a duct
describe endocrine glands
no connection to epithelium surface
hormones secreted in blood
what is the functions of connective tissue
bind tissue
acts as a transport system
store energy reserve
forms sheath separating organs
attaches skin to tissue
what is the structure of connective tissue
viscous solution with cells and fibres in the matrix
what are the 5 categories of connective tissue
loose connective tissue
dense connective tissue
cartilage
bone
blood
where is loose connective tissue found
hypodermis
what is the structure of loose connective tissue
cells is loose network of collagen and elastin fibres
does loose connective tissue have blood and nerve supply  
yes
describe the structure of dense connective tissue
closely packed collagen with little matrix
where is dense connective tissue found
where strength is needed
what are the 2 types of arrangement for dense connective tissue
regular
irregular
what does cartilage consist of
collagen and elastin
does cartilage have blood supply  
no
where does cartilage receive nutrients  
perichondrium
what is the function of bone
protect and support
does bone have blood and nutrient supply  
yes
what tissue is responsible for the formation of blood cells
haemopoietic tissue
