Hypothalamic-hypophysial relationships in the South American lungfish Lepidosiren paradoxa

General and Comparative Endocrinology, 1973
Abstract An analysis of the anatomical relations between the hypothalamus and the hypophysis of the South American lungfish Lepidosiren paradoxa , has shown the coexistence of peptidergic fibers which end on the portal vessels of the median eminence and a direct adrenergic innervation of the glandular cells of the adenohypophysis.

Topological analysis of the brain stem of the lungfish Lepidosiren paradoxa

Journal of Comparative Neurology, 1979
AbstractThe ventricular sulcal pattern and the cellular structure of the brain stem of the lungfish Lepidosiren paradoxa have been studied in transversely cut Nissl and Bodian stained sections. Five longitudinal sulci, the sulcus medianus inferior, the sulcus intermedius ventralis, the sulcus limitans, the sulcus intermedius dorsalis and the sulcus ...

Histology and ultrastructure of the neurohypophysis of the south american lungfish, Lepidosiren paradoxa

Zeitschrift f�r Zellforschung und mikroskopische Anatomie, 1972
The neurohypophysis of the South American lungfish Lepidosiren paradoxa has been studied with light and electron microscopy, including the Falck-Hillarp technique for catecholamines. The pars nervosa hypophyseos is a well-marked, dorsally located subdivision of the pituitary gland composed of lobes or follicles, each one constituted of a central core ...

Testosterone-induced development of limb gills of the lungfish, Lepidosiren paradoxa

Comparative Biochemistry and Physiology Part A: Physiology, 1973
Abstract 1. 1. Parenteral administration of testosterone enanthate in the lungfish, Lepidosiren paradoxa , induces growth of pectoral and pelvic hindlimb vascular filaments. 2. 2. The filaments have the microstructure of primitive gills, and are comparable to the nuptial developments of the male in the Paraguayan Chaco described by ...

Respiratory Function in the South American Lungfish, Lepidosiren Paradoxa (Fitz)*

Journal of Experimental Biology, 1967
ABSTRACT Few animal species have aroused as much excitement upon their discovery as the South American lungfish. Its possession of distinct piscine as well as amphibian characters made the animal a link in the transition of vertebrate life from water breathing to air breathing.

Morphology and function of the feeding apparatus of the lungfish, Lepidosiren paradoxa (Dipnoi)

Journal of Morphology, 1986
AbstractThe feeding mechanism of the South American lungfish, Lepidosiren paradoxa retains many primitive teleostome characteristics. In particular, the process of initial prey capture shares four salient functional features with other primitive vertebrates: (1) prey capture by suction feeding, (2) cranial elevation at the cranio‐vertebral joint during
