PSYB65H3 Chapter Notes -Sensory Neuron, Motor Neuron, Dendrite
Document Summary
Cell body (soma) core region of the cell containing the nucleus and other organelles for making proteins. Dendrite branching extension of a neuron"s cell membrane that greatly increases the surface area of the cell and collects information from other cells. Axon root" or single fiber, of a neuron that carries messages to other neurons. Dendritic spine prostrusion from a dendrite that greatly increases the dendrite"s surface area and is the usual point of dendritic contact with the axons of other cells. Axon hillock juncture of soma and axon where the action potential beings. Terminal button (end foot) knob at the tip of an axon that conveys information to other neurons. Synapse junction between one neuron and another that forms the information transfer site between neurons. Sensory neuron neuron that carries incoming information from sensory receptors into the spinal cord and brain.
