The ultrastructure of venom-producing cells in Paranemertes peregrina (Nemertea, Hoplonemertea)
Autor: Stephen A. Stricker, Richard A. Cloney
Publikováno v: Journal of morphology. 177(1)
The nemertean Paranemertes peregrina uses its long, eversible proboscis to capture nereid polychaetes. During prey capture, the glandular epithelium of the everted proboscis secretes a sticky venom that contains a potent neurotoxin. In this study, th

Origin and Differentiation of the Inner Follicular Cells during Oogenesis inMolgula pacifica(Urochordata), an Ascidian without Test Cells
Autor: Richard A. Cloney
Publikováno v: Acta Zoologica. 76:89-104
In Molgula pacifica small previtellogenic oocytes are found between cells of the ovarian epithelium. Each oocyte subsequently grows within a compartment of the epithelium known as a primary follicle. The wall of the primary follicle is composed of ou

Larval Tunic and the Function of the Test Cells in Ascidians
Autor: Richard A. Cloney
Publikováno v: Acta Zoologica. 71:151-159
In normal ascidian development, cuticular fins begin to form at the late tailbud stage and are fully formed at hatching. When one or several neurulae were manually demembranated (follicle cells, vitelline coat and test cells removed) and cultured in

Nervous system of ascidian larvae: Caudal primary sensory neurons
Autor: Steven A. Torrence, Richard A. Cloney
Publikováno v: Zoomorphology. 99:103-115
In larvae of Diplosoma macdonaldi one sensory nerve extends along the dorsal midline of the tail and another extends along the ventral midline. Each nerve is composed of 50–70 naked axons lying in a groove in the base of the epidermis, and each pro

Development of the larval tunic in a compound ascidian: morphogenetic events in the embryos of Distaplia occidentalis
Autor: Richard A. Cloney, Michael J. Cavey
Publikováno v: Canadian Journal of Zoology. 62:2392-2400
The larval tunic of Distaplia occidentalis is a complex investment consisting of extracellular filaments and an amorphous ground substance. The principal elements of the tunic are two thin cuticles and two subcuticular compartments. Compacted filamen

Fine structure and differentiation of ascidian muscle. II. Morphometrics and differentiation of the caudal muscle cells ofDistaplia occidentalis tadpoles
Autor: Richard A. Cloney, Michael J. Cavey
Publikováno v: Journal of Morphology. 144:23-69
The locomotor function of the caudal muscle cells of ascidian larvae is identical with that of lower vertebrate somatic striated (skeletal) muscle fibers, but other features, including the presence of transverse myomuscular junctions, an active Golgi

The stylet apparatus of the nemertean Paranemertes Peregrina: Its ultrastructure and role in prey capture
Autor: Stephen A. Stricker, Richard A. Cloney
Publikováno v: Zoomorphology. 97:205-223
The nemertean Paranemertes peregrina captures prey by using an eversible proboscis that is armed with a stylet apparatus. The apparatus consists of several reserve stylet sacs and a central stylet that is attached to a granular mass, called the basis

Chromatophore Organs, Reflector Cells, Iridocytes and Leucophores in Cephalopods
Autor: Richard A. Cloney, Steven L. Brocco
Publikováno v: American Zoologist. 23:581-592
The chromatophore organs of Lohgo are each composed of five types of cells: a central pigment cell: radially arranged, obliquely striated muscle fibers: neuronal processes; glial cells: and an investment of sheath cells. Sheath cells are absent in Oc

The influence of tunichrome and other reducing compounds on tunic and fin formation in embryonicAscidia callosa Stimpson
Autor: Kenneth Kustin, Richard A. Cloney, William E. Robinson
Publikováno v: Journal of Experimental Zoology. 237:63-72
Tunic in 46-hr-old Ascidia callosa larvae reared from dechorionated neurulae is either markedly reduced in thickness or absent altogether. The epidermis is fragile and cuticular fins fail to develop. Dechorionated neurulae treated with tunichrome and
