What's the difference between hellbender and mudpuppy?
Hellbender
Definition:
(n.) A large North American aquatic salamander (Protonopsis horrida or Menopoma Alleghaniensis). It is very voracious and very tenacious of life. Also called alligator, and water dog.
Example Sentences:
(1) But while freshwater species such as the European eel and the hellbender salamander in the US have crashed, recoveries have also been seen.
Mudpuppy
Definition:
Example Sentences:
(1) Inhibitory responses with similar kinetics were produced in heart muscles of the mudpuppy upon application of ACh.
(2) The OFF-ganglion cell population of the mudpuppy appears to be a heterogeneous group of cells.
(3) This technique, as well as a variation which causes mass staining of ganglion cell somas, has been used to analyze the morphology of mudpuppy retinal ganglion cells.
(4) The localization of two cytoskeletal proteins was analysed in the cell bodies and processes of ganglionic neurons and small, intensely fluorescent cells of the parasympathetic cardiac ganglion of Necturus maculosus (mudpuppy).
(6) Whole-cell recordings of amacrine and ganglion cells in the superfused retina-eyecup preparation of the mudpuppy were obtained in order to determine which excitatory amino acid receptor (EAAR) subtype mediates the synaptic responses of these neurons.
(7) The spatial properties of the trans- and intra-retinal oscillatory potentials (OPs), a- and b-waves of the mudpuppy electroretinogram (ERG) were analyzed.
(8) The mudpuppy retina contains both conventional and displaced ganglion cells: the latter constitute about 15% of the total ganglion cell population.
(9) Experiments were done using acutely dissected or organ cultured parasympathetic cardiac ganglion preparations from Necturus maculosus (mudpuppy).
(10) Over 65% of the synapses observed in the mudpuppy taste bud involved the basal cell.
(11) Intracellular recordings were obtained from taste receptor cells and surface epithelial cells of isolated mudpuppy lingual epithelium.
(12) Taste buds in the mudpuppy Necturus maculosus were examined with electron microscopy.
(13) The motoneurons innervating different regions of the myomeres in goldfish and mudpuppies were examined by applying HRP to the musculature or to branches of spinal nerves.
(14) This effect was blocked by dopamine antagonists, indicating that there is tonic GABA-mediated inhibition of dopamine release in mudpuppy retina similar to that previously reported by others in fish and turtle retinas.
(15) Experiments investigating both the binding of radioactively labelled saxitoxin (STX) and the electrophysiological response to drugs that increase the sodium permeability of excitable membranes were conducted in an effort to detect sodium channels in glial cells of the optic nerve of Necturus maculosa, the mudpuppy.
(16) Recordings of light-evoked changes in extracellular K+ concentration (delta[K+]o) were obtained in the retinas of frog and mudpuppy.
(17) In this report we describe the development of an in vitro preparation of the mudpuppy (Necturus maculatus) used to investigate locomotion in walking vertebrates.
(18) Previous studies have shown that mudpuppy taste receptor cells respond to sour taste stimuli (weak acids) with depolarizing receptor potentials or action potentials that are blocked by the K+ channel blocker tetraethylammonium.
(19) The present observations indicate that the mudpuppy cardiac ganglion exhibits a complex organization similar to that of mammalian sympathetic and enteric ganglia.
(20) Extracellular ganglion cell recordings in the perfused mudpuppy eyecup show that a chloride-free (c-f) perfusate abolishes the center and surround excitation of on-center cells, the surround excitation of off-center cells, and the on discharge of on-off cells.
