KEYWORDS
| Question | Answer |
|---|---|
| neuron: | a cell in neural tissue that is specialized for intercellular communication through changes in membrane potential and synaptic connections |
| reflex: | automatic reaction to a stimulus |
| nerve impulse: | a self-propagating wave of depolarization; also called an action potential |
| summation: | the accumulation of effects, especially those of muscular, sensory, or mental stimuli |
| plexus: | a network of interlacing nerves, blood vessels, or lymphatics |
| autonomic nervous system: | the division of the nervous system that functions involuntarily; innervates cardiac muscle, smooth muscle, and glands |
| motor nervous system: | carries impulses from the central nervous system to effector organs muscles and glands |
| somatic nervous system: | a division of the peripheral nervous system; also called the voluntary nervous system |
| acetylcholine: | a chemical transmitter substance released by certain nerve endings |
| afferent: | carrying to or toward a center |
| axon: | neuron process that carries impulses away from the nerve cell body; efferent process; the conducting portion of a nerve cell |
| central nervous system: | the brain and the spinal cord |
| conductivity: | ability to transmit an electrical impulse |
| dendrites: | the branching extension of neurons that carry electrical signals to the cell body; the receptive portion of a nerve cell |
| depolarization: | the loss of a state of polarity; the loss of a negative charge inside the plasma membrane |
| intersegmental reflex: | a reflex that involves several segments of the spinal cord |
| limbic system: | the group of nuclei and centers in the cerebrum and diencephalon that are involved with emotional states, memories, and behavioral drives |
| membrane potential: | (transmembrane potential) the potential difference, measured across a cell membrane and expressed in millivolts that results from the uneven distribution of positive and negative ions across the cell membrane |
| peripheral nervous system (PNS): | a system of nerves that connects the outlying parts of the body with the central nervous system |
| synapse: | the region of communication between neurons |
