2 A MANUAL OF ANATOMY 



Cephalic : towards the head. 



Clinoid : hke the knob of a bedpost. 



Condyle (' knuckle ') : a small round eminence covered by cartilage 

 — in reality a capitellum. 



Cotyloid : cup-like. 



Diaphysis {' grow between ') : this term is applicable to long 

 bones. It is the shaft of the bone, or the part which grows between 

 the epiphyses. 



Dorsal : pertaining to the back aspect. In man ventral and dorsal 

 are synonymous with anterior and posterior in the erect posture. 



Epiphysis (' grow upon ') : this is a process of bone which has 

 a secondary centre of ossification, and which is attached for a 

 time to the principal part of the bone by cartilage, but subse- 

 quently becomes consolidated. 



Facet (Fr. facette, ' a little face ') : a small plane articular surface. 



Fissure : a cleft or slit. 



Foramen : an opening in the sense of a hole. 



Fossa : a shallow depression. 



Glenoid : like a shallow socket. 



Groove : a furrow or gutter. 

 V Head : a rounded eminence, covered by cartilage, at the extremity 

 rl a bone. 



Hiatus : an opening in the sense of a gap. 



Malleolus : a small hammer. 



Meatus (pi. meatus): a passage or canal. 



Medullary : pertaining to the medulla or marrow. 



Neck : a constricted portion supporting a head. 



Neural : pertaining to the nervous system. 



Sinus or antrum : a cavity in the interior of a bone. 



spine : this is a sharp-pointed process, and in certain bones 

 is erroneously applied. 



Styloid : pen-like. 



Trochanter ('running round' or 'rolled'): a prominence which 

 has a rolled or wheel-like arrangement, and which runs round a 

 portion of a bone. 



Trochlea : a pulley. 



Tubercle ('swelling '): a small rounded prominence on a bone. 



Tuberosity : an exaggerated tubercle. 



Ventral : pertaining to the belly aspect of the body. 



Mesial plane : this is the imaginary longitudinal plane which 

 divides the body into two very nearly symmetrical halves, right 

 and left. It extends from the mesial line on the ventral aspect 

 to the mesial line on the dorsal aspect. 



Sagittal : this means pertaining to the antero-posterior mesial 

 plane with which it is parallel, and it practically means dorso- 

 ventral or antero-posterior. 



Coronal : this means intersecting the antero-posterior mesial 

 plane at right angles in a vertical direction, and it is practically 

 synonymous with transverse.
