| The histological examination was restricted to the endoneurium and the myelin sheath area. |
| The results show the instantaneous shear modulus of the ultrastructures in decreasing order is perineurium, endoneurium, and epineurium. |
| A hyper-viscoelastic model was employed to describe the elastic and stress relaxation response of each ultrastructure of the nerve, namely the endoneurium, the perineurium and the epineurium. |
| From F20 until the end of the experiment, the endoneurium of the peroneal nerve of experimental animals was more vascularized than that of intact group. |
| The endoneurium is continuous with the more abundant connective tissue perineurium, which envelops bundles of nerve fibers. |
| Individual nerve fibers are supported by a collagen-rich endoneurium and they are grouped in bundles, or fascicles, which are contained within the perineurium. |
