centeral nervous system correct answers part of the nervous system consisting of the brain and spinal cord Peripheral Nervous System (PNS) correct answers the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body. glial cells correct answers cells in the nervous system that support, nourish, and protect neurons Neuron correct answers a nerve cell; the basic building block of the nervous system Soma correct answers neuron cell body Axon correct answers the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands Dendrite correct answers the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body Gray matter correct answers a portion of the CNS consisting of cytons (cell bodies), their dendrites and synaptic connections white matter correct answers Whitish nervous tissue of the CNS consisting of neurons and their myelin sheaths. Myelin correct answers A layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the next. CNS tracts correct answers bundles of neuron processes in CNS sensory function correct answers The ability of the nervous system to sense changes in either the internal or external environment motor function correct answers The neuromuscular response to the sensory information Intergration correct answers interpretation of sensory input somatic nervous system correct answers A subdivision of the peripheral nervous system. Enables voluntary actions to be undertaken due to its control of skeletal muscles autonomic nervous system correct answers A subdivision of the peripheral nervous system. Controls involuntary activity of visceral muscles and internal organs and glands.
