MORPHOMETRIC ANALYSIS OF THE NERVE FIBERS OF THE ABDUCENT NERVE IN DOG
Abstract
The intracranial portion of the abducent nerve was studied in dogs. The nerves were dissected from six adult German shepherd dogs. The nerves were analysed by both light and electron microscopy. In all nerves we calculated their area and analysed both myelinated and unmyelinated fibers. In both we determined their number, diameter and area; also the area and diameter of the correspondent axon, and the thickness of the myelin sheath. The mean number of fibers was 2473.00±211.41 for myelinated and 231.25±92.67 for unmyelinated ones. The average fiber diameter was 10.45±1.27 µm for myelinated and 0.47±0.09 µm for unmyelinated. This study on the abducent nerve demonstrated that dogs shows structural and ultrastructural characteristics similar tothose of another nerves and other species.Downloads
