166 THE OSSEOUS TISSUE. 



Apophyses named according to the bodies to which they 

 are compared. 



Spines, resembling a thorn, as the spinous processes of 

 the vertebrae. 



Styloid, in the form of a conical point. 



Coracoid, like the beak of a crow. 



Odontoid, or tooth-like. 



Mastoid, like the nipple. 



Apophyses named according to their uses. 



Trochanters, or those subservient to turning, as the tro- 

 chanter major, and minor of the thigh bone. 



Orbitary, belonging to the orbit. 



Apophyses named according to their direction and rela- 

 tive situation. 



Oblique, transverse, anterior, &c. The cavities upon the 

 surface of bones have two divisions. 



1st. Articular cavities. 



2d. Those which do not belong to articulation. 



The first division includes the 



Cotyloid, (xotfrty, cup, c&So?, shape,) a cavity deep and round, 

 as seen at the thigh joint. 



Glenoid, (ya^, shallow,) shallow cavities, like that at 

 the shoulder joint. 



TrocJiliform, when scooped in the form of pulleys, as in 

 the elbow joint. 



Faces, when nearly plane. 



Alveoli, when of a conical form, as the sockets for the 

 teeth. 



The second division includes cavities not entering into 

 articulation. 



1. Cavities intended for the reception of parts. 

 FOSSCB, when the entrance is wider than the bottom. 

 Sinuses, when it is narrower. 



2. Cavities for the insertion of parts. 



Impressions, when they are wide, unequal and shallow 

 Grooves, when extended in length. 



3. Cavities for the passage of tendons. 



4. Cavities formed by the impression of parts.
