Document Summary
Chapter 2 cells and structures: the anatomy of the. All organs and muscles communicate with nervous system. Basic unit of nervous system containing dendrites (receptors), integrating cell body, conducting axon, transmitting axon terminal. Non-neuronal brain cells that provide structural, nutritional, and other types of support to the brain. Neurons are much larger and produce readily measured electrical signals. Showed that neurons come very close together but are not continuous. Neurons and other cells structurally, metabolically, and functionally independent. Information is transmitted from neuron to neuron across tiny gaps (synapses) The cellular location at which information is transmitted from a neuron to another cell. Part of a neuron that receives information from other neurons of from specialized sensory structures. Extension of the cell body that receives information from other neurons. May be elaborately branched to accommodate synapses from many other neurons. The part of a neuron that initiates nerve electrical activity.
