Document Summary
Types of neurons: motor neuron from spinal chord, purkinje cell, ganglion cell, mitral cell from olfactory bulb, pyramidal cell from cortex. Techniques for identifying neurons and tracing connections: golgi staining method, hrp (horseradish peroxidase, fluorescent carbocyanine dyes, placed close to neurons and dissolve in cell membranes and diffuse over the. Non-neuronal cells entire surface of the cell: astrocytes and oligodendrocytes (in mammalian cells, schwann cells (in peripheral nerves, do not have axons, dendrites, or specialized anatomical junctions with nerve cells, retinal glial cells known as m ller cells. Grouping of cells according to function: photoreceptors, horizontal, bipolar, amacrine, and ganglion cells have cell bodies and synapses in well-defined layers, photoreceptors, consists of rods and cones, both perform different functions. Initiated when localized gradient graded potentials are sufficiently large to depolarize cell membrane beyond threshold (critical level: propagate (spread) rapidly over long distances, have fixed amplitude and duration (all or none)
