In fact, the ganglionic corpuscles of each eye may be considered as constituting a little brain, connected with the masses behind by the commissure, commonly called the optic nerve. We are prepared, therefore, to find these two little brains in the most intimate relations with each other, as we find the cerebral hemispheres.
The nervous system consists of a large supra-oesophageal ganglion in the first segment; then of a chain of ganglia, one to each segment, on the ventral side of the body. With one ganglion in each segment there is far more controlling, perceptive, ganglionic material than in lower worms.
Importance of some knowledge of the body and its needs Fearful responsibility of entering upon domestic duties in ignorance The fundamental vital principle Cell-life Wonders of the microscope Cell-multiplication Constant interplay of decay and growth necessary to life The red and white cells of the blood Secreting and converting power The nervous system The brain and the nerves Structural arrangement and functions The ganglionic system The nervous fluid Necessity of properly apportioned exercise to nerves of sensation and of motion Evils of excessive or insufficient exercise Equal development of the whole.
The nervous system the more comprehensive term for its organic apparatus is variously developed in different classes and species, and also in different individuals, the volume or mass bearing a general relation to the amount of power. In the mollusca and crustacea we see simply a ganglionic cord pervading the extent of the body, and sending out lateral filaments.
Whatever instincts they possess they brought with them from the wild thousands of years ago. Therefore, all Rollo's actions were ganglionic discharges mechanically determined by the instincts that had been developed and fixed in the species thousands of years ago. Very well.
That in civilized communities dyspepsia is a very common disease. 2d. That dyspeptics require rest of mind and body to facilitate the laborious process of digestion. Cæteris paribus, these same propositions may be held of those suffering from abnormal modes of activity in another part of the ganglionic system that connected with menstruation.
Every portion of the body has nerves of sensation coming from the spine, and also branches of the sympathetic or ganglionic system. The object of this is to form a sympathetic communication between the several parts of the body, and also to enable the mind to receive, through the brain, some general knowledge of the state of the whole system.
How high, for instance, stand the vertebrates above the invertebrates! Yet how could the first deviation from the ganglionic system of the nerves of the invertebrates to the cerebro-spinal system of the vertebrates have occurred? and, especially, how could the first deposit of the vertebral column have procured any benefit to the individual in the struggle for existence?
Ill, believe me, would this work-day world get on if all within it were hard-reading, studious animals, playing the deuce with the ganglionic apparatus. Leonard started as he heard the knock at the door; the parson's well- known voice reassured him. In some surprise he admitted his visitors. "We are come to talk to you, Leonard," said Mr. Dale; "but I fear we shall disturb Mrs. Fairfield."
The influence of Beecher over her would be ganglionic as well as intellectual; that of Tilton purely intellectual: when lo, a gust of ganglionic power would supervene on the latter, and carry all before it. Concluding his analysis of Mr. Beecher thus, Mr. Burns discovered that he had two clerics among his audience, and asked us for I was one of them if we would be examined.
