The plantar muscles of the great toe are involved in many foot pathologies,
including hallux valgus. Forces acting along their tendons are important
considerations in analyzing gait patterns and arch stability. Muscle models have
not been constructed at the fiber bundle level, but rather using a series of single
or multiple line segments to represent a muscle. The purpose of this study is to
construct, at fiber bundle level, a volumetric 3D model of the plantar muscle of
the great toe. In situ digitization with a Microscribe TM G2DX digitizer of one
formalin embalmed cadaveric specimen was used to develop a 3D prototype
model of abductor, adductor, and flexor hallucis muscles. Autodesk ® Maya ® , with
additional plugins developed in this laboratory, were used to create a model the
digitized data. Using this technique, a detailed model at the fiber bundle level was
constructed and used to visualize and quantify the musculotendinous architecture
of the plantar great toe muscles. This prototype may be further developed into
a contractile model that enables functional analysis in normal and pathologic
scenarios.

tongue

Objective: We aimed to clarify whether there are the structurally differences of the
filiform and the fungiform papillae of human tongue depending on their position
and function.
Methods: The tissue specimens were separated to the significant parts: the tip, the
body and the root of tongue and processed with the scanning electron microscopy
SEM JCM5700, Jeol, Tokyo, Japan and the light microscopy.
Results and discussions: The tip of tongue is the first sensing place for taste
stimuli and the most active moving side. Consequently, the free longbased
fungiform papillae distributed equable densely and a few filiform papillae
containing the less and strong hairs placed along the margin of the fungiform
papillae. The body of human tongue is the main mastication area. And it contained
the numerous filiform papillae which are composed of a lot of hairs for making
the soft sponge structure and holding the tongue plaque. In the root, the both of
filiform and fungiform papillae were changed responding to the frictional stress as
the swallowing.
Conclusion: The structural variations of filiform and fungiform papillae might be
depended on their positional role.
