PSY290H5 Chapter Notes - Chapter 2: Axon Terminal, Sensory Neuron, Motor Neuron
Document Summary
Chapter 2: cells and structures the anatomy of the nervous system. Neurons: also called nerve cell, it is the basic unit of the nervous system. Each is composed of receptive extensions called dendrites, and integrating cell body, a conducting axon, and a transmitting axon terminal. Each neuron receives inputs from many other neurons, interprets those inputs, and then distributes the processed information to other neurons. Non-neuronal brain cells that provide structural, nutritional, and other types of support to the brain (also participate in information processing) Although neurons come very close together, they are not quite continuous with one another the neuron doctrine: the neurons and other cells of the brain are structurally, metabolically and functionally independent. Information is transmitted from neuron to neuron across tiny gaps named synapses. Synapse: the cellular location at which information is transferred from a neuron to another cell.
