88 SPECIAL ANATOMY. 



Direction: from above to below, and from without to within, 

 particularly in the female. 



Connection : with the acetabulum of the pelvis and the shin- 

 bone. 



a. Superior extremity taking a course from the shaft or centre piece 

 from without, inwards and upwards. On it, 



1. Caput femoris, head of the thigh bone, almost two-thirds of a sphere with 

 foved, for ligam. teres. 



2. CoUum, neck of the thigh bone ; forms with the central piece an obtuse 

 angle ; fiat. Anterior surface short, posterior longer and rather concave. 

 Behind it 



3. Trochanter Major, above and externally in a plane with the corpus femo- 

 ris, for m. glutceus med. and minimus, pyriformis, quadratus femoris, with : Fossa 

 trochanterica, for m. gemelli et obturatores. 



4. Trochanter Minor, below and internally from the base of the neck, for 

 the tendon of the m. Psoas et iliacus. 



5. Linen intertrochanterica anterior, for m. cruralis, posterior, [part] for m. 

 quadratus femoris. 



b. Centre piece, body. Anterior surface rather convex, inferior broader 

 than above, for m. cruralis. Internal surface, flat, below broader and directed 

 backwards, indicating course of art. femoralis. External surface, narrow, in 

 the longitudinal direction rather concave ; the external and internal borders 

 are roundish. Posterior border, sharp and rough, the Linea aspera; above and 

 below divided. Above, the external angle terminates in the Trochant. major, 

 the internal, the more feeble, in Troch. minor. 



Internal angle, for m. pectineus adductor brevis, vastus intern. 



External angle, for m. Glut&us max., adductor magnus, vastus externus, Caput 

 breve bicipitis. 



Centre, the linea aspera, for m. adductor longus et magnus, with: Foramen 

 nutritium. Below, the Linea aspera terminates in the two condyles, for the 

 in. gastrocnemii, between which is a triangular space, the superior part of the 

 fossa poplitcea, for art. ven., et nerv. poplitceus. 



c. Inferior extremity broad, flat from before to behind j with 



1 . Condylus externus, for m. Poplitceus, plantaris, Cap. extern, m. gastroc. upon 

 a plane with the corp. femoris. 



2. Condylus intern, projects very much inwards from the axis, for Cap. 

 intern, m. gastroc. 



On the articular head : 



1. Inferior articular surface, for the tibia and patella. 



2. Tuberositas interna projects greatly; over it a surface, for m. adduct. mag- 

 nus ; externa, less marked, with a tubercle. Both for ligamenta cruciata. 



Between them : 



3. Posterior Fossa intercondyloidea, forms the fossa of the knee. 



4. Anterior Trochka femoris, corresponds to the Patella. 

 Structure : type of the long bones. 



Development: five osseous centres: one, for the body, one for 

 each extremity, one for each Trochanter. The first appears in 

 the body, between the fortieth and fiftieth days ; the second in the 

 inferior extremity, regularly, in short, before the maturity of the 

 fostus ; the third 'in the middle of the head at the end of the first
