Botrylloides leachii WBR has been reported to start with the healing of the injury sites to prevent further hemolymph loss, followed by the compaction of the marginal ampullae
toward the center of the remaining matrix.
The response of the ampullae
of Lorenzini of elasmobranchs to electrical stimulation.
The reproductive cycle was studied by analyzing the monthly variation in the proportion of spermatophore-bearing females and males with terminal ampullae
filled with sperm masses.
BONUS: The shark, ray, and skate have sensors called Ampullae
of Lorenzini that are connected to pores in their skin and transmit electrical signals to their brains.
size (ejaculate volume) may still modulate spermatophylax size through influences of ejaculate protection, while the primary factors influencing spermatophylax size itself are paternal investment.
The contents of the inner ear are removed, including the otolithic organs, especially the utricle with its attached ampullae
beneath the horizontal fallopian canal.
The first two have a complex spermatheca, with digitiform prolongations on the duct, while the second two have similar terminal ampullae
, but the duct is smooth.
Inside the inner ear, the labyrinthine artery divides into the anterior vestibular artery and the common cochlear artery: the former provides blood to the ampullae
of the anterior and horizontal semicircular canals, the utricle and a small part of the saccule; the latter branches into the posterior vestibular artery and the main cochlear artery, the first of which supplies blood to the remainder of the saccule and the posterior semicircular canal ampulla (Baloh, 1996b).
The Shark POD was designed to stimulate gel-filled organs - known as ampullae
of Lorenzini - that detect electrical fields, and other sensors that detect vibration.
Oil from the lamps which burned at this site was highly prized by pilgrims as an eulogia or "blessing," and they carried it away in small metal phials known as ampullae
The little tinlead, purse-shaped ampullae
that were issued at Canterbury in Chaucer's time contained miraculous water that had been, it was claimed, in touch with the blood of the martyr St Thomas.
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.
