ax·on ter·mi·nals

the somewhat enlarged, often club-shaped endings by which axons make synaptic contacts with other nerve cells or with effector cells (muscle or gland cells). Axon terminals contain neurotransmitters of various kinds, sometimes more than one. These can be demonstrated by chemical analysis and immunocytochemical methods.
See also: synapse.

Papillated stylodes occur on the parapodia and there are compound falcigers in the neuropodia. The bidentate neurosetae have 4 rows of small spines on the manubrium.
Neuropodia of first chaetiger as low transverse ridges, from chaetiger 2 to 14 (Fig.
Orbinia hartmanae Day, 1977, from Australia (Day 1977), is the most similar species, with 12-21 thoracic chaetigers, branchiae from chaetiger eight, four rows of thoracic uncini, a similar number of postchaetal processes on thoracic neuropodia and of stomach papillae on first abdominal chaetigers, and flail-tipped chaetae.
Scoloplos (Leodamas) johnstonei Day, 1934 from Southern Africa and Australia (Day 1967, 1977), is a second species that also bears flail-tipped chaetae and a few subpodial and stomach papillae on first abdominal chaetigers, as well as thoracic neuropodia with four rows of uncini and one or two postchaetal processes, but it possesses 18-24 thoracic chaetigers, branchiae from chaetiger six onwards, and furcated notopodial chaetae on abdomen.
Orbinia riseri (Pettibone, 1957), from western Atlantic (Pettibone 1957, 1963, Day 1973, Taylor 1984), is similar to the new species in having branchiae that begin on chaetiger 8-10, thoracic neuropodia with four rows of uncini and 2-3 postchaetal processes, interramal cirri on abdominal neuropodia, and a low number of stomach papillae.
It possesses thoracic neuropodia with four rows of uncini and several postchaetal processes and anterior abdominal neuropodia with interramal cirrus and two or three subpodial papillae; in addition, Day (1977) recorded the occurrence of a few stomach papillae, although they were not mentioned in the original description.
Neuropodia with a papilliform postchaetal process from chaetiger 7 (Fig.
The posterior three segments of this region consist of highly modified neuropodia forming fans termed palettes that pump water through the animal's tube by a metachronal, rhythmic movement (MacGinitie, 1939; Barnes, 1965).
