Vagus nerve {Ans: wide distribution}spinal nerves {Ans: associated with the spinal cord and are parallel bundles of axons and their associated neuroglial cells wrapped in several layers of connective tissue}Interneurons (association neurons) {Ans: located in CNS between sensory and motor neurons. Integrate incoming sensory information}Trigeminal nerve {Ans: three branches, Ophthalamic nerve, Maxillary nerve, Mandibular nerve}ANS effectors {Ans: smooth muscle, cardiac muscle, glands}functional classification of nerve fibers reason {Ans: neurons are classified according to the direction in which the nerve impulses (action potentials) is conveyed with respect to the CNS}Oligodendrocytes {Ans: myelin sheath}Facial nerve {Ans: face}neuroglia of PNS {Ans: Schwann cells, satellite cells}ANS two divisions {Ans: sympathetic and parasympathetic}Trochlear nerve {Ans: eye mover}Abducens nerves {Ans: eye mover}Vestibulocochlear {Ans: auditory}neuroglia of CNS {Ans: oligodendrocytes, astrocytes, microglia, ependymal}neuroglia {Ans: Half of the volume of the CNS}Not decremental {Ans: keeps its strength as it spreads along the membrane - propagation - depends on positive feedback}sensory function {Ans: detect stimuli}motor function {Ans: elicit an appropriate response by activating effector}neuroglia function {Ans: Actively participate in the activities of nervous tissue}spinal cord end {Ans: near the level
