    the skin; (2) secondary neurones whose body Hes in the central nervous organs and whose axon extends thence to some other part of the central nervous organs to terminate about a primary neurone. These neurones may lie in the cortex and brain or in the basal ganglia or medulla. All simple reflex acts involve the transmission of impulses through primary neurones only. All transmission of voluntary motor impulses, or conscious sensory impulses, involves the action of both primary and sec- ondary neurones. The human nervous system has two distinct portions: (i) the cerebro-spinal sy.'^tem, and (2) the sympathetic nervous sys- tem. (i) The cerebro-spinal system includes: (o) a peripheral portion, comprising the nerves, (b) a central system, comprising: (i) the spinal cord and cranial nerve nuceli; (ii) the cerebellum gray masses of the medulla, pons, crura cerebri, corpora quadri- gemina, optic thalami and corpora striata; (iii) the cerebral cortex. (2) The sympathetic nervous system is subdivided into: (a) Two great cords containing ganglia, which lie on the sides of the vertebral column and are joined to the spinal cord on one side and to the plexuses on the other; (b) Three pervertebral plexuses, the cardiac, solar, and hypogastric, which are masses of ganglia connected with the viscera; (c) ]\lany peripheral plexuses connected with various organs; (d) Terminal mono- cellular ganglia scattered through the viscera; (e) Sympathetic nerve-fibres joining the plexuses and ganglia together and con- necting them with the cerebro-spinal system.
