insertion of the capsular ligament, and quadratus femoris,
another line on the fore part of the bone, extending between
the two trochant ers, for the insertion of the capsular ligament.
The body of this bone is smooth and convex before, and hol-
low behind, where there is a rough line, called linea aspcra :
it originates near the trochanters, and extends to the lower
extremity, where it divides, and terminates in a protuberance
behind each condyle. On the inferior extremity are the ex*
ternal and the internal condyle, and between them posteriorly
a deep notch, for the passage of the great artery, vein, and
nerve of the leg.
Substance. Compact on the outside, spongy in the extre-
mities, and cancellated internally.
Connexion. The femur is connected to the acetabulum of
the os innominatum by enarthrosis, and to the tibia and patella
by ginglynius.
Joint. The hip joint is formed by the acetabulum, the
deep hollow cavity of the os innominatum, and the head of
the thigh-bone which it receives. The socket is lined by car-
tilage, which rises on its edge, so as to deepen its cavity ; the
notch observed on the dry bone, at the inferior part, has a
ligament stretched across it; the round ligament keeps the
head of the thigh-bone down in its socket, and a very strong
capsular ligament surrounds the whole joint. The varied
motions of the joint are facilitated by the synovia secreted,
particularly by a substance placed within the socket.
Use. To form part of the lower extremity.
The thigh-bone, at birth, is of the same shape as the adult
femur. Its head is cartilage, its inferior extremity an
epiphysis. The ossification of this bone, as well as of
the os brachii, begins a month after conception, and
has the same shape at four months as at nine.
A longitudinal section of the adult femur, beautifully ex-
hibits the three substances of bones, viz. the retku-
insertion of the capsular ligament, and quadratus femoris,
another line on the fore part of the bone, extending between
the two trochant ers, for the insertion of the capsular ligament.
