This Issue's Question:

In the last issue of Body Cast, Rounds asked:
What are the

The following answers were received:
From Janet Cannon and Mike Walker:
The three hallucal sesamoids of the great toe provide medial/
lateral stability of the first MTP. Two are almost always present
on the plantar aspect of the MTPl, and one may be present on
the plantar aspect of IPl. The three important functions of the
hallucal sesamoids of the great toe are 1) weight bearing, 2)
reduces friction, and 3) protects tendons.
From Brad DeWagner:
Three important functions of the hallucal sesamoids of the
great toe are: elevation of the metatarsal head, increase the
mechanical advantage of the ft.exor hallucus brevis muscle of
the great toe and assist with weight bearing under first MT.
From Cynthia Brown:
Three functions of the hallucal sesamoids of the great toe: protect
tendons, absorb weight-bearing pressure, and reduce friction.
