Definitions: Journal Post 2

This week was all about epithelial tissues in Histology. There were some concepts where I wanted a little more understanding so I decided to define and explain them in this weeks blog.

Psuedostratified Epithelium- This is when cells do not completely reach the free surface but all are on the basement membrane. The cell do not fully connect to these parts.



Basal Lamina- This component acts as an attachment to the rest of the structure as well and separates the epithelium from the connective tissue. It also aids in filtration.

Zonula Occludens- These structures are also known as tight junctions. They create a barrier which allows for tight seals, causing selective permeability.


The pictures found came from the following website. The descriptions and explanations were very helpful and allowed me to understand each concept a little better.
