Document Summary
Neuron basic unit of the nervous system a single cell: supported by glia cells. Dendrites-branch off of cell body (root means tree: collects info from impacting neurons. Axon-nerve impulse, long part of neuron: myelin sheath- glia cell that wrapped itself around axon. All-or-nothing principle: stimulated until certain point then released full speed, ex. Chain reaction of electrochemical changes along the axon. Propagation the down axon: ion movements: sodium=na, potassium=k+ Intensity of experience rate of firing place of firing pattern of firing . Neurotransmitter molecules are stored in packets within the cell called: synaptic vesticles. Which of the following is the product of a glia cell: myelin sheath. Which of the following parts of a neuron has terminal buttons: axon. Which of the following is associated with parkinson"s disease: dopamine. Input (receiving: receptor, sensory neurons processing, interneurons output (responding, motor neurons, effector. Which of the following is not true: the brain is bilaterally symmetrical in function.
