The lamellar cells of the sensory corpuscles of the pig dermis must be considered to be epithelial cells as they contain cytokeratins. The cytokeratins detected are similar to those found in simple epithelia. Moreover, lamellar cells are embedded in an extracellular matrix reminiscent of the basement membrane of epithelium since it contains laminin and

Sensory Receptors as a Special Class of Hormonal Cells
Neuroendocrinology, 2008Classically, sensory receptors are specialized cells which detect specific environmental disturbances and send out neural signals for the integration, control and/or regulation of effector organs. Recently, a special class of sensory receptors called sensori-hormonal cells which employ hormones as their means of flux of biological information has been ...

Development of the Sensory Receptor Cells in the Utricular Macula
Otolaryngology–Head and Neck Surgery, 1978Normal CBA mice were timed for the developmental stage by the vaginal plug technique. The day of copulatory plug observance was designated as gestation day one. The developmental characteristics of the utricular macula sensory epithelium is described on an ultrastructural level from the 15th to the 19th day of gestation (approximate day of birth).

Studies on the Sensory Hairs of Receptor Cells in the Inner Ear
Acta Oto-Laryngologica, 1977The crista ampullaris of the semicircular canal in the frog can be isolated and mounted in a chamber so that the sensory hairs can be observed under high magnification in interference-contrast. The cupula is removed and the sensory hairs can be manipulated and their mechanical properties investigated by a microprobe held in a micromanipulator.

Micromechanical properties of sensory hairs on receptor cells of the inner ear
Hearing Research, 1983The aim of the investigation was to obtain quantitative measures of mechanical filter properties of hair cell sensory hairs which were not restricted to move by auxiliary structures. The specimen used was the crista ampullaris of the frog, dissected free and positioned in a fluid-filled chamber where it could be viewed with differential interference ...

Noxious heat receptors present in cold-sensory cells in rats
Neuroscience Letters, 2004Noxious heat above approximately 45 degrees C applied on cold spots evokes a paradoxical cold sensation by activating cold fibers. It remains unresolved whether cold receptors respond to heat as well, or whether noxious-heat receptors and cold receptors coexist in the same fiber.

Nerve Dependency of Developing and Mature Sensory Receptor Cellsa
Annals of the New York Academy of Sciences, 1998ABSTRACT: Old and recent data concerning development of sensory cells and trophic interdependency of sensory neurons and sensory cells is reviewed for the ear, the lateral line system, the electroreceptive system, and the taste system. All sensory neurons originate from placodes. However, only most ear, lateral line and electrosensory cells derive from

The ultrastructure of the sensory hairs of the paratympanic organ receptor cells in chicken
Anatomy and Embryology, 1996The hair bundle of the receptor cells in the paratympanic organ of the chicken was studied by TEM, after fixation in aldehydes/osmium tetroxide or in aldehydes/osmium tetroxide/tannic acid. The bundles are formed by a kinocilium and by 40-70 stereocilia. The stereocilia are linked to each other by an extensive network of filaments. Three types of these

Sensory receptor-like cells in the human foetal vomeronasal organ
NeuroReport, 1993The vomeronasal organ (VNO) was studied in ten human foetuses, 12 to 36 weeks old. At 12 to 23 weeks, it was lined by a smooth pseudostratified epithelium, with neurone-specific enolase (NSE) positive cells looking like olfactory receptors. Clusters of NSE-positive cells were seen in relation with the posterosuperior end of the organ and along nerve ...

Calcium currents and GABAB receptors in the dorsal sensory cells of the lamprey spinal cord
Neuroscience and Behavioral Physiology, 1999Patch-clamp studies were performed on the isolated dorsal sensory cells of the spinal cords of three species of lamprey, Ichthyomyzon unicuspis, Petromyzon marinus, and Lampetra fluviatilis, to measure changes in the amplitudes of calcium current induced by GABA and its specific antagonists and agonists.
