Document Summary

Psy 2301 d biological foundations of behavior. A cell body; the core region of the cell containing the nucleus and other organelles for making proteins. The junction between one neuron and another that forms the information transfer site between neurons. The root" or a single iber of a neuron that carries messages to other neurons. The juncture of soma and axon where the action potential begins. Also called the end foot; a knob at the tip of an axon that conveys information to other neurons. Branching extension of a neuron"s cell membrane that greatly increases the surface area of the cell and collects information from other cells. Protrusions from a dendrite that greatly increase the dendrite"s surface area and are the usual point of contact with the axons of other cells. Sensory neuron with one axon and one dendrite. Association neuron interposed between a sensory neuron and a motor neuron; (in mammals) most of the neurons in the brain.
