Nervous System 4

Nervous System IV: Professor Diamond continues her discussion of the nervous system, finishing her discussion of the derivatives of the neural tube. She begins by discussing the lamina terminalis and the four ventricles, relating each to the source of their derivation and the areas of the brain in which they are found. Next, she continues her discussion of diencephalon from the last lecture and describes the roles of the thalamus and hypothalamus. After describing the hypothalamus’s function as the control center of the automatic nervous system, Professor Diamond discusses the derivatives of the telencephalon – the basal ganglia and the cerebral hemisphere. She draws a diagram of how the basal ganglia is related to the caudate nucleus, the lentiform nucleus, the putemen, the globus pallidus, and the subthalamus. Next, she discusses the reasons for the existence of gyrus and sulcus in the cerebral hemisphere before diagramming the lateral fissure, central sulcus, frontal, parietal, occipital, and temporal lobes, as well as the insula. She concludes with slides showing myelinated fibers, synapses, and other topics discussed throughout this lecture.
