Document Summary
2 sensory input simple reflex. higher consciousness motor output. The anterior most areas become kind of a brain. They can propagate electrical signals but not action potentials. 7 two neurons connected in a circuit presynaptic cell communicates with the postsynaptic cell through the synapse output in axons. axon hillock: where the axon meets the cell body axon termin. 8 neurons in different shapes and sizes the retina: highly layered structure. the cerebellum: huge dendritic arborization. Spinal cord neuron: axons can often be incredibly long. Many molecules in the bloodstream that can normally get to cells, cannot pass through the bbb because the astrocytes provide a screening process. Protecting the brain form possible toxins designing drugs that can pass through the bbb. Schwann cells in the pns around the axons wrapped lipid bilayer multiple layers around the axons. acts like rubber insulation along wires.
