6 Reasons Your Vagina Hurts - Health 1, cerebral ganglion, 2, posterior do., 3, 4, 5, 6, thoracic ganglia, 7, 8, 9, 10, 11, 12, abdominal ganglia, o, o, o, system of transverse nerves, more distinctly seen in fig. 3, by which 3, 4, 5, signify the three thoracic ganglia, a, a, central nervous filet, b, b, b, b, nerves furnished by this filet, c, c, c, c, nervous threads separating from the preceding nerves, and which, by uniting after they reach the ganglion, represent the central thread. When ganglia don’t exist within the abdomen, the nerves descend in lengthy threads from the thoracic knots. The posterior thoracic ganglia are practically united into one mass; and all the nerves furnished by these ganglia to the locomotive organs, will be seen to have acquired a substantial improvement. At one extremity they are connected to the inside of the exterior crust, and the varied processes related therewith, at the other to the organ on which they are designed to operate, their attachment being both rapid or by way of a tendon. Nervous System.-The important and singular department of the animal economic system now to be briefly considered, is moderately of a simple nature in insects, that’s, in its exterior and material properties, for the manner through which it obeys the commands of the governing principle is simply as refined and mysterious on this as in any other branch of the animal kingdom.

Lac, a substance of properly-recognized utility within the arts, as getting into into the composition of varnish, sealing-wax, &c., is the glutinous and semitransparent transudation of the Coccus lacca, which envelopes its complete physique after it has fixed itself to the branch of a tree, based on the manner of its congeners.

Muscles of the Thorax.-The muscular system of the thorax has for its office to unite the part segments of that portion of the body, and to furnish a motive apparatus for the organs of locomotion, the wings and legs.

Vascular System.-F. E. Beddard, varied papers on vascular system of Ophidia and Lacertilia, P.Z.S. From it the muscles derive the irritability which places them in action; by way of the nerves the intestinal canal is excited to motion, and, by the impulse of the identical organs, the sexual elements exercise the operate appointed to them. These information are chiefly the following:-the sunshine is subject to the need of the animal; it becomes extra sensible when its motions are violent; a certain diploma of heat is important for its display, and its depth increases as much as 40° R. when it becomes extinct, as it likewise does when the cold is at 10° R.; oxygen renders it more brilliant for a short while, but soon extinguishes it; the identical effect is produced extra speedily by irrespirable gases, and by inserting it in a vacuum; the phosphorescence quickly disappears after the demise of the animal, however might be restored by heat water, oil, or alcohol; galvanic electricity excites it; and, lastly, when the insect is kept for a while in the dead of night, the luminosity disappears, however is restored by publicity to the light of the sun.
