How to identify stratifed cuboidal epithelium in histological slide

 How to identify stratifed cuboidal epithelium in histological slide 

1. only 2-3 cells layers are present

2. name of stratified epithelium are decided according to the shape of the surface cell

Ex: ducts of sweat glands

1. single layer of tall  and short columnar shape ( height  of some cells are more and height of some cells are less but all cells rest on basement membrane )cells rest are on basement membrane

2. cell contain single centrally place oval  nuclei , located near the basal region

3. Level of nuclei are different so it is look like stratified epithelium but all cells are rest on basement membrane . it stratified epithelium only basally place cells layer rest on basement membrane . other cells layer rest on previous cell layer .

Ex: lining epi of trachea, bronchi, epididymis, vas deferens

How to identify simple columnar  epithelium in histological slide 

1. single layer of columnar  shape ( height more and width less)cells are rest on basement membrane

2. cell contain single centrally place oval  nuclei , located near the basal region

ex: lining epi. of stomach, lining epi. of gall bladder  


 


How to identify simple cuboidal epithelium in histological slide

 How to identify simple cuboidal epithelium in histological slide 

1. single layer of cuboidal shape (same height and width) cells are rest on basement membrane

2. cell contain single centrally place round  nuclei

ex: thyroid follicles, kidney tubules

How to identify Simple squamous epithelium in histological slide

1. single layer of flattened cells are rest on basement membrane

2. cell contain single centrally place flattened oval nuclei

ex: endothelium, mesothelium, endocardium
