Document Summary
Neuron: the basic unit of the nervous system that operates through electrical impulses, which communicate with other neurons through chemical signals. 3 functions: neurons receive (reception), integrate (conduction), and transmit (transmission) information in the nervous system. Dendrites: branchlike extension of the neuron that detect info (chemical signals) from other neurons. Cell body: in the neuron, where info from thousands of other neurons is collected and processed. Axon: a long narrow outgrowth of a neuron by which information is transmitted to other neurons. Nerve refers to a bundle of axons. Terminal buttons: small nodules at the ends of axons that release chemical signals from the neuron to an area called the synapse. Synapse: the site for chemical communication between neurons. Sensory neurons: afferent neurons that detect info from the physical world and pass that info along to the brain. Motor neurons: efferent neurons that direct muscles to contract or relax, thereby producing movement.
