[sect. 18. 



6. Tendons, ligaments, fibrous membranes, fibro-cartilage. 



7. Bones and teeth. 



8. Smooth muscles and muscular membranes. 



9. Transversely striped muscles and muscular membranes. 



10. Nerves and ganglia. 



11. Simple glandular follicles. 



2. Compound Organs. 



12. Vessels. 



13. Vascular membranes (external skin, mucous and se- 



rous membranes, proper vascular coats). 

 14- Special organs of the intestinal canal. 



15. Compound true glands, with their individual sections. 



16. Compound vascular glands (spleen, tonsils, supra-renal 



capsules) . 



17. Central organs of the nervous system. 



18. Higher organs of the senses. 



The organs lastly unite to form special systems, of which the 

 following may be distinguished : — 



1. The System of the External Shin, consisting of the corium, 

 epidermis, the horny structures, and the larger (mammary glands) 

 and smaller glands of the skin. 



2. The Osseous System, comprehending the bones, cartilages 

 ligaments, and articular capsules. 



3. The Muscular System, viz: the muscles of the trunk and 

 extremities, the tendons, fasciae, tendinous ligaments and bursas 

 mucosae. 



4. The Nervous System, consisting of the large and small 

 central organs, the nerves and higher organs of the senses. 



5- The Vascular System, consisting of the heart, the blood and 

 lymph vessels, as well as the lymphatic glands. 



6. The Visceral System, comprising the intestinal canal, the 

 organs of respiration, with the thymus and thyroid, the salivary 

 glands, the liver and spleen. 



7. The Urinary and Sexual Systems. 



Since the individual organs and systems will be spoken of in 

 detail in the special part, we do not require to enter here into a 

 more minute description of them; and it accordingly only remains 

 to characterise the tissues themselves somewhat more minutely 

 while, at the same time, a few general remarks concerning the 

 organs may be most fitly annexed.
