flrO ANATOMY. 



Describe the Phalanges. The finger-bones are 14 in number (15 accor* 

 ing to Pancoast), 3 to each finger, and 2 to the thumb. They are long bones, 

 and each has a base, a shaft, and a digital extremity. The Bases of the first 

 row articulate with the heads of the metacarpal bones. The Digital Extremities 

 of the first and second rows have each 2 small lateral condyles, while in the 

 terminal row they are rough, for the attachment of the sensitive pulp of the 

 fingers. 



BONES OF THE LOWER EXTREMITY. 



THE THIGH. 



Describe the Femur. The thigh-bone is nearly cylindrical, and is the 

 longest, largest, and strongest bone in the body. In the ver- 

 tical position of the skeleton it forms one side of a triangle, 

 of which the base is the breadth of the pelvis, and the apex 

 at the knee-joints. The base of this triangle is longest in the 

 female, and consequently that sex is usually knock-kneed. 

 Headfi articulates with the acetabulum, forms about two- 

 fifths of a sphere, and has an oval depression^ below its 

 centre for the attachment of the ligamentum teres. 

 Neckf connects the head with the shaft, is pyramidal and 

 flattened ; its obliquity varies with age, being less before 

 puberty, about 120 to 125 degrees in the adult, and nearly 

 horizontal to the shaft in old or debilitated subjects. 

 Great Trochanter^ a broad, rough, quadrilateral process 

 directed outwards and backwards from the summit of 

 the shaft to within three-fourths of an inch of the level 

 of the head. On its outer surface the tendon of the 

 gluteus maximus plays over a bursa. It gives insertion 

 to the obturator internus, two gemelli, pyriformis, and 

 gluteus minimus and medius muscles. 

 Digital Fossa, on the inner surface of the great trochantei, 



gives insertion to the obturator externus muscle. 

 Lesser Trochanter,e at the inferior root of the neck pos- 

 teriorly, is small and conical, and affords insertion to the 

 tendon of the psoas magnus muscle, the tendon of the 

 iliacus being inserted immediately below it. 

 Inter-trochanteric Lines, anterior and posterior, the latter the most prominent ; 



to the anterior is attached the capsular ligament of the hip-joint. 

 Linea Quadrati, extends from the middle of the posterior inter-trochanteric 

 line about 2 inches down the shaft, and gives attachment to the quadratus 

 fcnaaris muscle.
