Hello, dear observers. In today's video lesson, we will study the motor nerves of the cranial nerves. So, as we introduced in the last lesson , the motor cranial nerves include the third, fourth, sixth, eleventh, and twelfth cranial nerves, which are considered pure motor nerves. When we went over motor pathways with you , we talked about how they have two

neurons. Okay, and we talked about the pathways that lead from the cranial nerves to the nuclei in the corticonuclear pathways. So, these cranial nerve pathways are also two-neuron, and their first neuron is the neuron that goes from the cortex to the cranial nerve roots , that is, it is the main first neuron. And in

today's lesson, we'll look at peripheral neurons , the neurons located in the periphery. Okay, so I have to mention one more thing , we've looked at the nuclei of all the cranial nerves , except for the first and second cranial nerves, which don't have any nuclei in the brain. We reviewed their conductive paths

with you in the last lesson. So, in today's lesson, we'll start with the third nerve, the oculomotor nerve, which is the nerve that moves the eye. The nucleus of this nerve is located in the midbrain. If you remember, the midbrain contained the nuclei of the third and fourth cranial nerves . So, in the midbrain,

I drew four mounds in the front of the midbrain, which are the brainstem, and four mounds in the back. This is a sagittal section. The pons, medulla oblongata, and cerebellum are better visible. Okay, and the aqueduct of Sylvius ran through the middle of the midbrain, the fourth ventricle. So, the nucleus of the third pair of cranial nerves is located
