Perineurium | cellular layer around each fascicle; vasculature, epithelial-like cells, "blood-nerve barrier" |
Endoneurium | sparse reticular and collagen fibers, fibroblasts. |
What layer of PNS nerve cells contains Schwann cells, Myelin sheaths, and axons? | Endoneurium |
Are there any vessels in the endoneurium layer? | essentially there are no vessels. |
Groups of nerve cells in the PNS. | Ganglia (pl) or ganglion (s) |
