■ The anatomical simulator of the spinal cord and spinal nerves is magnified by 5 times, consisting of 2 thoracic vertebrae and 4 pairs of spinal nerves. The spinal cord runs through the spinal canal as a cylinder, and on the transverse plane of the spinal cord, the gray matter of the butterfly shaped structure located in the center and the white matter surrounding it can be observed. The upper segment of the simulator's spinal cord is free, showing three layers of different thicknesses of outer membranes, namely the dura mater, arachnoid membrane, and soft spinal membrane, and dissecting the layers of the membranes, Display the anterior and posterior roots of spinal nerves; On both sides of the spinal cord, there are anterior and posterior roots that combine to form spinal nerves that exit the intervertebral foramen. The communicating branches of the spinal nerves connect the sympathetic nerve trunks located on both sides of the vertebral body.
