Document Summary
Chapter twelve: identify the major structures and functions of the nervous system in the maintenance of homeostasis, nervous system. Ii. organization of the nervous system central nervous system (cns: brain, spinal cord. Xi. peripheral nervous system (pns) nerve cranial nerves spinal nerves ganglion (plural is ganglia) enteric plexuses sensory receptor somatic nervous system (sns) autonomic nervous system (ans: sympathetic, parasympathetic. Xiii. enteric nervous system (ens) functions of the nervous system: sensory function, integrative function, motor function effector, compare the histological characteristics of neuroglia and neurons, histology. Iii. electrical excitability action potentials (or nerve impulses) parts of a neuron: cell body, nissl bodies, dendrite, axon, axon hillock initial segment, trigger zone, axon collateral, axon terminal, synapse, synaptic end bulb, varicosities, synaptic vesicle, neurotransmitter structural classification. Viii. bipolar neuron unipolar neuron functional classification: sensory, motor, interneurons, describe the major functions of neuroglia, neuroglia or glia, astrocytes, oligodendrocytes, myelin sheath.
