Physiological Skeleton Name
English
The Forearm
The connection in the elbow joint makes realistic flexion and extension possible as well as good transfer
of force between the upper and lower arm. The rotating movement of the forearm between the ulna and
radial (pronation and supination) are also possible.
The Hands
Since the assembly of the hand is relatively fixed in order to achieve stability, movement of the carpalia
(wrist bone) is limited. Flexion of the fingers and thumb opposition can be easily simulated.
The Hip Joint
The condyle of the femur and the socket of the hip bone are connected realistically making movement of
the thigh possible in all physiological directions including rotation around the vertical axis. The transfer of
force and movement from the leg to the hip and spinal column is also easily recognizable.
The Knee
The lower leg can be flexed and extended. Outward and inward rotations are easily possible within their
natural limits.
The Foot
Both the tarsal bones and the bones of the individual phalanges are connected to one another elastically
and facilitate good mobility in all of the joints.

Repair kit
In case a screw is lost, a rubber band breaks from excessive pressure or a spring gives way, spare parts are
contained in the enclosed repair kit.
