The scheme is important to researchers, since these laminae correspond to the functional differences in organization of the spinal cord. In general sensory systems are organized hierarchically. Sensory systems are organized in parallel pathways. The larger the diameter of the sensory fiber the faster the conduction velocity. II Extreme Joint angle and capsule pressure D. Afferents for different modalities go to different laminae within the dorsal horn.
Hair cells center around lamia III .
B. Interneurons may have excitatory and inhibitory influences. C. Propriospinal neurons connect different segments within the spinal cord. V. Motoneurons A. Motoneurons are very large cells with complex dendritic trees ramifying in the grey matter and the white matter. This latter group of muscles is important for the stretch reflex. There is a somatotopic arrangement of the motor columns within the ventral horn.
