And for our consciousness of our trunk and our limb we have the spinal cord pass with this. So from the T4 region of our spinal cord we have the ascending pathway sended the information of our trunk on the limb to the spinal cord. And through the spinal cord the information will go up to the cortex, and then the cortex will process the information and will sense the feeling from out trunk, our limb and very fine touch. So the information first get into the spinal ganglion and will get the fasciculus, and then will go into the secondary neuron get a relay in the secondary neuron and through the medial lemniscus. Go to the third neuron and then go to the central thalamic radiation. So the unconsciousness pathway of our body, it gets into the primary neurons from the spinal ganglion, and then the information will go, so posterior spinocerebellar tracts. And from this tract, will go into the superior cerebellar peduncle or inferior cerebellar peduncle. So that's how we sense our unconsciousness of feelings. And therefore our pain, temperature and a simple touch of the trunk and the limb. So the primary sensory neuron is also spinal ganglia and then the secondary is the lamina. And then the information will go through the spinal cord, through the anterior spinothalamic tract or lateral spinothalamic tract, and up to VPL is the third neuron in the relay system and then the information will go to the central thalamic radiation. So for pain temperature simple touch of the head and the face. So information will collect it through high interface by the primary neuron of trigeminal ganglions, and the information will go to the secondary neuron impulse. So the secondary neuron impulse will send to the information up to the third on neurons in VPM. And in the VPM maps send information up to the cortex, the central thalamic radiations. So visual pathway, so this is the basic structure of our visual pathways. So that the original information get into our retina and then the retina will send the information to the optical nerve. The optical nerve goes, will send the information to the lateral geniculate body right here. Sometimes the information will send the same size, and sometimes will cross the optical chasm and into the other side of the cortex. And if the information after the lateral geniculate body, the information will get into the optical rendition and from the optical radiation will project to the optical areas of our brain. The auditory pathway. So the auditory, So the auditory information will get collected by our ear and transfer from our cochlaeus and then the electrosignal will send to from the cochlea, or send to cochlea nerve. Cochlea nerve send information through the lateral lemniscus to medial geniculate body, through medial geniculate body will go to the cortex caustic radiation. The corticospinal tract. The corticospinal tract control our movement and a locomotor activities. So the lower motor neuron will have the information collected and then the lower motor neuron will send the information through lateral corticospinal tract up to corticospinal tract and it's through the corticospinal tract to the upper motor neuron.
