This activation of the bile-treated acanthocephalans was also manifested by an eversion of the proboscis.
Backbone compression favors eversion of the now extrahelical nucleotide, which is positioned for recognition by the uracil-binding motif.
There can be associated eversion of the eyelids (ectropion).
This can be caused by excessive external rotation, inversion or eversion of the foot caused by an external force.
During eversion, the yolk of the host oocyte fills the gastral cavities of the parasite, supplying the future free-living stage with nutrients.
Average subtalar motion is 20-30 degrees inversion and 5-10 degrees eversion.
Functional motion during the gait cycle is 10-15 degrees (the heel strikes the ground in slight inversion followed by quick eversion).
Upon approaching an eversion point, the music of the possible destination becomes audible.
