7. What are five different types of protein channels in the phospholipid bi-layer of the cell and what function does each play? 8. Name the types of tissue groups.

9. What type of epithelial tissue is considered avascular?

10. Describe the characteristics of simple squamous epithelial cells:

Please, I need this for my anatomy midterm.

7) Ans :-

8) Ans :- These categories are epithelial, connective, muscle, and nervous.

9) Ans :- Epithelial tissues are nearly completely avascular. For instance, no blood vessels cross the basement membrane to enter the tissue, and nutrients must come by diffusion or absorption from underlying tissues or the surface. Many epithelial tissues are capable of rapidly replacing damaged and dead cells.

10) Ans :- A simple squamous epithelium is a single layer of flat cells in contact with the basal lamina (one of the two layers of the basement membrane) of the epithelium. This type of epithelium is often permeable and occurs where small molecules need to pass quickly through membranes via filtration or diffusion.
