ANATOMY IN A NUTSHELL. 



LESSON I. 



Anatomy is concerned with the form, structure and connections of the parts 

 of the body. It has the following divisions: 



1. Osteology (os-te-ol-o-je) is the anatomy of the bones. 



2. Syndesmology (sin-dez-mol-o-je) is the anatomy of the joints. 



3. Myology (mi-ol-o-je) is the anatomy of the muscles. 



4. Angiology (an-je-ol-o-je) is the anatomy of the vessels. 



5. Neurology (nu-rol-o-je) is the anatomy of the nerves. 



6. Splanchnology (splangk-nol-o-je) is the anatomy of the viscera. 



7. Adenology (ad-en-ol-o-je) is the anatomy of the glands. 



8. Dermatology (der-mat-ol-o-je) is the anatomy of the skin. 



9. Genesiology (jen-e-ze-ol-o-je) is the anatomy of the generative organs. 

 Aponeurosis (ap-on-u-ro-sis) is the end of a muscle where it becomes a 



tendon. 



(a) It is any fascia or fascial structure, especially the tendons of a muscle 

 when broad, thin, flat and of a glistening white color. 



(b) It is the expansion of a tendon covering more or less of a muscle. 



(c) It is a thin, whitish ligament. 



The name was given to these structures when they were supposed to be 

 expansions of nerves — any hard, whitish tissue being then considered nervous. 

 In present tisage aponeurosis is nearly synonymous with fascia, but it is oftener 

 applied to the fascia like tendons of muscles; as the aponeurosis of the external 

 oblique of the abdomen. (Plate XV.) 



Fascia is a sheet or layer of dense connective tissue. The general contour 

 of the body is invested, just beneath the skin, with a thin, light fascia, as dis- 

 tinguished from the thicker, tougher and more densely fibrous deep fascia 

 which invests and forms sheaths for muscles and dips down among the mus- 

 cles and bundles of muscular fibers forming intermuscular septa. 



A tendon is a hand or layer of dense fibrous tissue at the end of a muscle 

 for attachment to a hard part. A very hard flat tendon is called fascia and 

 aponeurosis. Tendons are directly continuous at one end with the periosteum 

 and at the other end with the' fascial tissue which invests the muscle. 



A sinus means a cavity in hone or other tissue. The sinus of the superior 

 maxillary hone is called the antrum of Highmore. The veins of the dura mater 

 are called sinuses.
