Detail Introduction:
Function: The model shows that sensory fibers conduct proprioception, tactile sensation Pain sensation, motor fiber conduction, visceral and somatic motor conduction And corresponding effectors. 31 pairs of spinal nerves, each pair of spinal nerves Connected to a spinal cord segment, each pair of spinal nerves is connected through the anterior root In the anterior lateral sulcus of the spinal cord; Connecting the posterior root to the lateral sulcus of the spinal cord. Both the front and back roots are composed of many root filaments, and generally the front root belongs to transport Dynamic, posterior root belongs to sensory, both located at the intervertebral foramen Synthesize a spinal nerve that contains both sensory fibers and synkinesis Fibers are mixed. The posterior root of the spinal nerve is attached to the intervertebral foramen There is a nearly elliptical enlargement called the spinal ganglia, which contains pseudoganglia Unipolar sensory neurons, in which the axon forms the spinal nerve Posterior root. 31 pairs of spinal nerves divided into 5 parts, 8 pairs of cervical nerves, and 12 pairs Thoracic nerves, 5 pairs of lumbar nerves, 5 pairs of sacral nerves, and 1 pair of caudal nerves through
