PSY290H5 Lecture Notes - Lecture 3: Myelin, Alessandro Volta, Luigi Galvani
Document Summary
Upcoming test: 30-40 multiple choice questions, 4 short answer questions, there will be diagrams, but only those from lecture, only assigned textbook readings will be assigned, and will be very broad. Note: notice that from each branch" of the dendrites, extends two other branches". One of these is used to receiving information, and another is used to send information. Golgi-stained pyramidal and stellate neurons: cortical pyramidal cells, generally considered to be multipolar, cortical stellate cells, inhibit the activity of some. Three fibre types compose the cytoskeleton of axons: the tubules help transport proteins from the cell body to the extensions of the neuron, the filaments tend to be associated with providing structural support to the neurons, cont. Glial cells support axon function: glial cells assist neuronal activity by providing raw materials, chemical signals, and structure, myelin is produced by glial cells in the neurons, myelination occurs through oligodendrocytes in the cns (brain), but through.
