Document Summary
Cell body, contains the nucleus, sums up the input: axon. Long extended fiber along which the neural impulse travels, sends signal out: terminal buttons. Swollen bulb-like structures that contain neurotransmitters found at the end of the axon. Action potentials: properties of the action potential. The size of the action potential is unaffected by increases in the intensity of stimulation beyond the threshold level. A period during which further stimulation can not cause another action potential. The gap between one neuron and another: synaptic transmission. The relaying of information from one neuron to another across the synaptic gap: neurotransmitters. Brain structures: lower level structures (basic life processes) Cerebellum (coordination, balance: limbic system (emotion, motivation, memory) Hypothalamus (maintenance, reward: the cerebral lobes and cerebral cortex. Motor cortex: controls the action of the body"s voluntary muscles, the right motor cortex controls the left side of your body, the left motor cortex controls the right side of your body!
