Document Summary
Motor or efferent: autonomic nervous system (receives info, sends commands to heart and other organs) Explain how the structural and functional features of neurons allow them to process and transmit information. Dendrites: receive info or converted, the energy of external stimulation into the cell body analyzes it. Info is passed on to the next neuron at the axon terminal until it reaches the spinal cord. Signal is sent to the muscles through spinal reflex, body withdraws from pain. Signal also sent to the brain itself which interprets the sensation as painful. Neuron is sufficiently depolarized it will generate an action potential, if it does not reach the threshold of activation, impulse will decay rapidly and will not reach the end of the axon (cid:0) Describe a synapse and the effects of synaptic transmission. Synapse: conjunction of a terminal button of one neuron and the membrane of another.
