The connecting branch between the deep branch of the @entity4957 often has an enlarged site. We investigated these enlarged sites of the connecting branches. We observed the 22 @entity1 feet of 20 Japanese cadavers. We investigated the connecting branch macroscopically and histologically. We found the connecting branches between the deep branch of the @entity4957 in 19 feet out of 22 feet. This connecting nerve branch was interposed between the tendon of the @entity1795 longus and the @entity1795 brevis, and there enlarged in the anteroposterior direction. After penetration, numbers of fascicles of this connecting branch were increased at the enlarged site. In this region, the connective tissues surrounding the nerve fascicles and vessels were more developed compared with the adjoining sides of this branch. A few fascicles at this enlarged site innervated the first metatarsophalangeal joint capsule. Other nerve fascicles arose from the connecting branch and branched off muscular branches to the @entity1795 brevis. This branch possibly receives the physical exertion or friction during gait due to its position. Deformity and overload of the foot can cause @entity74 of the foot, but the anatomical basis for the relationship between the deformity/overload and @entity74 of the foot is unclear. We discussed that this connecting branch can be a potential cause of pressure @entity16 in the @entity1 foot.
