INTRODUCTORY. 



THE term " anatomy," derived from the Greek am, 

 "through," and re/xi/ew, "to cut," signifies dissection, but has 

 been appropriated to the science which treats of the apparent 

 properties of organized bodies. It is the science of organization. 

 Anatomy is divided into vegetable, which treats of the structures 

 and properties of vegetal bodies; comparative, which treats of 

 the anatomy of animals ; human, which treats of the anatomy of 

 man in a physiological or healthy state; pathological, which 

 treats of the anatomy of the diseased human body, etc. 



Human anatomy is subdivided into general, descriptive, and 

 surgical. 



General anatomy treats of the minute structure or physical 

 elements of the organs of the body. It is also called micro- 

 scopical anatomy, or histology. It comprises seven distinct 

 classes : 



Corpuscular, including the blood, spleen, etc. 



Epithelial, including mucous mejnbranes, epidermis, glands, etc. 



Cartilaginous, including cartilage, fibre-cartilage, etc. 



Osseous, including all bony structures. 



Muscular, including flesh and muscle generally. 



Nervous, including the proper nerve elements. 



Connective, including white fibrous, elastic, adipose, and neuroglia. 



Descriptive or special anatomy treats of the various proper- 

 ties of the organs arranged into systems; hence the name 

 systematic. It includes: 



Osteology, the anatomy of the bones. 

 Syndesmology, the anatomy of the joints. 

 Myology, the anatomy of the muscles. 

 Angiology, the anatomy of the vessels. 

 Neurology, the anatomy of the nerves. 

 Splanchnolog3 r , the anatomy of the viscera. 

 Dermatology, the anatomy of the skin. 

 Genesiology, the anatomy of the generative organs. 

 Adenology* the anatomy of the glands, etc., etc. 



Surgical or topographical anatomy treats of the relative 

 position of organs to one another and to the surrounding parts 

 in special regions of the body, as the axilla, neck, or groin.
