The response of the ampullae
of Lorenzini of elasmobranchs to electrical stimulation.
Zygotes were collected 16 h post-hCG from the oviduct ampullae
of superovulated females that had been mated with the same strain of males.
Some electroreceptive animals sense electric charges with sensors called Ampullae
The contents of the inner ear are removed, including the otolithic organs, especially the utricle with its attached ampullae
beneath the horizontal fallopian canal.
30 Nature, he concluded that a temperature change in seawater of less than a thousandth of a degree Celsius would induce a voltage in the gel filling the ampullae
large enough for the shark to detect.
help the shark find prey at close range by homing in on electrical impulses generated by muscle movement.
In addition to decorations on ampullae
and other pilgrim "souvenirs," its architectural form was replicated both on a small scale - for example, the fragment of a stone model preserved in the Musee lapidaire at Narbonne - and also at something approaching full size.
Ringing the tiny petals are even tinier tentacle-like ampullae
, the sensing organs that evaluate other sea squirts, determining who's related and who isn't.
Spermathecae small, variably shaped, ampullae
elongated, paired or multiple, with pores pretestical, testical, or post-testical; in one to six intersegmental furrows: 9/10-15/16, 16/17.
B) It gives off a high-pitched noise detected by sharks' ampullae
Sharks (but not the large pelagic teleosts targeted by longline fisheries) possess a unique sensory system based on the ampullae
of Lorenzini that can detect electric field gradients as small as 5 nV/cm (Haine et al.
The art of the early Christians shown in the exhibition is one primarily oriented around Rome and Italy: there is little sense of the simultaneous development of Christian art in the eastern Mediterranean, the images connected with the growing cults of ascetic saints in Syria and Egypt in the fourth and fifth centuries; or the various pilgrim tokens and ampullae
that were produced to service pilgrims visiting the loca sancta of the Holy Land.
Pronuclear (one-cell zygote) embryos were teased out of the ampullae
, and cumulus masses were removed by a 3-to 5-rain incubation in 0.
