=Ox.=—The proximal end of the fibula fuses with the external condyle of
the tibia. The distal end remains separate, and forms an arthrosis with
the distal end of the tibia; the movement here is imperceptible, as the
two bones are closely united by strong peripheral fibers.
=Pig.=—The superior joint is provided with a capsule which is reinforced
in front and behind by fibrous tissue.
The interosseous ligament attaches the shaft of the fibula to the outer
border of the tibia.
The inferior joint is included in the capsule of the hock joint, and is
strengthened by oblique anterior and posterior ligaments. There is also
an interosseus ligament.
=Dog.=—The arrangement is essentially the same as in the pig, but there
is no interosseous ligament in the inferior joint.
